This delivers 64 bit index BLAS libraries alongside 32 bit ones. This is often
called ILP64 in the BLAS world, as opposed to LP64 where integers are 32 bit
due to the Fortran default integer type, not to be confused with the basic
system ABI used by C. For really large vectors on modern machines, you want
an 'ILP64' BLAS and layers on top of it.
In preparation of better support for vendor BLAS libraries, I had to realize
that you better use the C interfaces supplied by them, not the netlib one
strapped on. A simple reason of practicability: The vendor blas libraries,
just like openblas, like to ship all symbols in one library, so you get them
whether you want it or not. Also implementations may skip Fortran and implement
the underlying functionality directly in C anyway, so one might skip a
layer of indirection. Future will tell if other layers will follow. We still
have the framework of individual layers from Netlib to combine with certain
implementations that miss them (Accelerate framework comes to mind, which
needs further work).
The framework of netlib reference packages for the separate libraries
is instructive and helps keeping things small when you not need all of them.
The installation location of the headers is now in a subdirectory to be able
to have 32 and 64 bit variants independently. The 32 bit ones are linked to
${PREFIX}/include to keep the old picture. We could be brave and remove
those, but there is some value in a build just trying -lcblas and
inclusion of <cblas.h> to be happy.
There is one blas.buildlink3.mk that is supposed to be used only once and
so avoids a combination of conflicting libraries (as the 64 bit index symbols
have the same names as the 32 bit ones).
Basic usage for getting LAPACK+BLAS is still the same as before. You get
CBLAS and LAPACKE by setting BLAS_C_INTERFACE=yes in the package. The 64 bit
indices are selected via BLAS_INDEX64=yes.
Due to the special nature of the Accelerate framework, a package has to
explicitly indicate support for it and it will also not appear on the
list of implementations by default. The reason is that it does provide
mainly CBLAS and CLAPACK (another version of C interface to LAPACK, f2c-based)
and BLAS/LAPACK with f2c/g77 calling conventions. A default build with
gfortran would not like that
This commit also fixes up math/py-numpy and math/py-numpy16 to follow the
new scheme, as that are the only packages directly affected by the change
in CBLAS providership.
Change the way iconv_t void* conflict is handled
using a patch from upstream to fix PR pkg/56240 .
Due to the above remove
patch-libinterp_corefcn_input.cc and
patch-liboctave_wrappers_iconv-wrappers.h .
Execute autoconf in the configuration step so that
patch-configure.ac and patch-m4_acinclude.m4 is
actually used.
Change the PLIST so that -gnu is not used
references in patch-m4_acinclude.m4 mentions this.
Explicitly don't generate any docs since

CHANGES IN R 4.1.0:
FUTURE DIRECTIONS:
* It is planned that the 4.1.x series will be the last to support
32-bit Windows, with production of binary packages for that
series continuing until early 2023.
SIGNIFICANT USER-VISIBLE CHANGES:
* Data set esoph in package datasets now provides the correct
numbers of controls; previously it had the numbers of cases added
to these. (Reported by Alexander Fowler in PR#17964.)
NEW FEATURES:
* www.omegahat.net is no longer one of the repositories known by
default to setRepositories(). (Nowadays it only provides source
packages and is often unavailable.)
* Function package_dependencies() (in package tools) can now use
different dependency types for direct and recursive dependencies.
* The checking of the size of tarball in R CMD check --as-cran
<pkg> may be tweaked via the new environment variable
_R_CHECK_CRAN_INCOMING_TARBALL_THRESHOLD_, as suggested in
PR#17777 by Jan Gorecki.
* Using c() to combine a factor with other factors now gives a
factor, an ordered factor when combining ordered factors with
identical levels.
* apply() gains a simplify argument to allow disabling of
simplification of results.
* The format() method for class "ftable" gets a new option justify.
(Suggested by Thomas Soeiro.)
* New ...names() utility. (Proposed by Neal Fultz in PR#17705.)
* type.convert() now warns when its as.is argument is not
specified, as the help file always said it _should_. In that
case, the default is changed to TRUE in line with its change in
read.table() (related to stringsAsFactor) in R 4.0.0.
* When printing list arrays, classed objects are now shown _via_
their format() value if this is a short enough character string,
or by giving the first elements of their class vector and their
length.
* capabilities() gets new entry "Rprof" which is TRUE when R has
been configured with the equivalent of --enable-R-profiling (as
it is by default). (Related to Michael Orlitzky's report
PR#17836.)
* str(xS4) now also shows extraneous attributes of an S4 object
xS4.
* Rudimentary support for vi-style tags in rtags() and R CMD rtags
has been added. (Based on a patch from Neal Fultz in PR#17214.)
* checkRdContents() is now exported from tools; it and also
checkDocFiles() have a new option chkInternal allowing to check
Rd files marked with keyword "internal" as well. The latter can
be activated for R CMD check via environment variable
_R_CHECK_RD_INTERNAL_TOO_.
* New functions numToBits() and numToInts() extend the raw
conversion utilities to (double precision) numeric.
* Functions URLencode() and URLdecode() in package utils now work
on vectors of URIs. (Based on patch from Bob Rudis submitted
with PR#17873.)
* path.expand() can expand ~user on most Unix-alikes even when
readline is not in use. It tries harder to expand ~, for example
should environment variable HOME be unset.
* For HTML help (both dynamic and static), Rd file links to help
pages in external packages are now treated as references to
topics rather than file names, and fall back to a file link only
if the topic is not found in the target package. The earlier rule
which prioritized file names over topics can be restored by
setting the environment variable _R_HELP_LINKS_TO_TOPICS_ to a
false value.
* c() now removes NULL arguments before dispatching to methods,
thus simplifying the implementation of c() methods, _but_ for
back compatibility keeps NULL when it is the first argument.
(From a report and patch proposal by Lionel Henry in PR#17900.)
* Vectorize()'s result function's environment no longer keeps
unneeded objects.
* Function ...elt() now propagates visibility consistently with
..n. (Thanks to Lionel Henry's PR#17905.)
* capture.output() no longer uses non-standard evaluation to
evaluate its arguments. This makes evaluation of functions like
parent.frame() more consistent. (Thanks to Lionel Henry's
PR#17907.)
* packBits(bits, type="double") now works as inverse of
numToBits(). (Thanks to Bill Dunlap's proposal in PR#17914.)
* curlGetHeaders() has two new arguments, timeout to specify the
timeout for that call (overriding getOption("timeout")) and TLS
to specify the minimum TLS protocol version to be used for
https:// URIs (_inter alia_ providing a means to check for sites
using deprecated TLS versions 1.0 and 1.1).
* For nls(), an optional constant scaleOffset may be added to the
denominator of the relative offset convergence test for cases
where the fit of a model is expected to be exact, thanks to a
proposal by John Nash. nls(*, trace=TRUE) now also shows the
convergence criterion.
* Numeric differentiation _via_ numericDeriv() gets new optional
arguments eps and central, the latter for taking central divided
differences. The latter can be activated for nls() via
nls.control(nDcentral = TRUE).
* nls() now passes the trace and control arguments to getInitial(),
notably for all self-starting models, so these can also be fit in
zero-noise situations via a scaleOffset. For this reason, the
initial function of a selfStart model must now have ... in its
argument list.
* bquote(splice = TRUE) can now splice expression vectors with
attributes: this makes it possible to splice the result of
parse(keep.source = TRUE). (Report and patch provided by Lionel
Henry in PR#17869.)
* textConnection() gets an optional name argument.
* get(), exists(), and get0() now signal an error if the first
argument has length greater than 1. Previously additional
elements were silently ignored. (Suggested by Antoine Fabri on
R-devel.)
* R now provides a shorthand notation for creating functions, e.g.
\(x) x + 1 is parsed as function(x) x + 1.
* R now provides a simple native forward pipe syntax |>. The
simple form of the forward pipe inserts the left-hand side as the
first argument in the right-hand side call. The pipe
implementation as a syntax transformation was motivated by
suggestions from Jim Hester and Lionel Henry.
* all.equal(f, g) for functions now by default also compares their
environment(.)s, notably via new all.equal method for class
function. Comparison of nls() fits, e.g., may now need
all.equal(m1, m2, check.environment = FALSE).
* .libPaths() gets a new option include.site, allowing to _not_
include the site library. (Thanks to Dario Strbenac's suggestion
and Gabe Becker's PR#18016.)
* Lithuanian translations are now available. (Thanks to Rimantas
Zakauskas.)
* names() now works for DOTSXP objects. On the other hand, in
R-lang, the R language manual, we now warn against relying on the
structure or even existence of such dot-dot-dot objects.
* all.equal() no longer gives an error on DOTSXP objects.
* capabilities("cairo") now applies only to the file-based devices
as it is now possible (if very unusual) to build R with Cairo
support for those but not for X11().
* There is optional support for tracing the progress of
loadNamespace() - see its help.
* (Not Windows.) l10n_info() reports an additional element, the
name of the encoding as reported by the OS (which may differ from
the encoding part (if any) of the result from
Sys.getlocale("LC_CTYPE").
* New function gregexec() which generalizes regexec() to find _all_
disjoint matches and well as all substrings corresponding to
parenthesized subexpressions of the given regular expression.
(Contributed by Brodie Gaslam.)
* New function charClass() in package utils to query the
wide-character classification functions in use (such as
iswprint).
* The names of quantile()'s result no longer depend on the global
getOption("digits"), but quantile() gets a new optional argument
digits = 7 instead.
* grep(), sub(), regexp and variants work considerably faster for
long factors with few levels. (Thanks to Michael Chirico's
PR#18063.)
* Provide grouping of x11() graphics windows within a window
manager such as Gnome or Unity; thanks to a patch by Ivan Krylov
posted to R-devel.
* The split() method for class data.frame now allows the f argument
to be specified as a formula.
* sprintf now warns on arguments unused by the format string.
* New palettes "Rocket" and "Mako" for hcl.colors() (approximating
palettes of the same name from the 'viridisLite' package).
Contributed by Achim Zeileis.
* The base environment and its namespace are now locked (so one can
no longer add bindings to these or remove from these).
* Rterm handling of multi-byte characters has been improved,
allowing use of such characters when supported by the current
locale.
* Rterm now accepts ALT+ +xxxxxxxx sequences to enter Unicode
characters as hex digits.
* Environment variable LC_ALL on Windows now takes precedence over
LC_CTYPE and variables for other supported categories, matching
the POSIX behaviour.
* duplicated() and anyDuplicated() are now optimized for integer
and real vectors that are known to be sorted via the ALTREP
framework. Contributed by Gabriel Becker via PR#17993.
GRAPHICS:
* The graphics engine version, R_GE_version, has been bumped to 14
and so packages that provide graphics devices should be
reinstalled.
* Graphics devices should now specify deviceVersion to indicate
what version of the graphics engine they support.
* Graphics devices can now specify deviceClip. If TRUE, the
graphics engine will never perform any clipping of output itself.
The clipping that the graphics engine does perform (for both
canClip = TRUE and canClip = FALSE) has been improved to avoid
producing unnecessary artifacts in clipped output.
* The grid package now allows gpar(fill) to be a linearGradient(),
a radialGradient(), or a pattern(). The viewport(clip) can now
also be a grob, which defines a clipping path, and there is a new
viewport(mask) that can also be a grob, which defines a mask.
These new features are only supported so far on the Cairo-based
graphics devices and on the pdf() device.
* (Not Windows.) A warning is given when a Cairo-based type is
specified for a png(), jpeg(), tiff() or bmp() device but Cairo
is unsupported (so type = "Xlib" is tried instead).
* grSoftVersion() now reports the versions of FreeType and
FontConfig if they are used directly (not _via_ Pango), as is
most commonly done on macOS.
C-LEVEL FACILITIES:
* The _standalone_ libRmath math library and R's C API now provide
log1pexp() again as documented, and gain log1mexp().
INSTALLATION on a UNIX-ALIKE:
* configure checks for a program pkgconf if program pkg-config is
not found. These are now only looked for on the path (like
almost all other programs) so if needed specify a full path to
the command in PKG_CONFIG, for example in file config.site.
* C99 function iswblank is required - it was last seen missing ca
2003 so the workaround has been removed.
* There are new configure options --with-internal-iswxxxxx,
--with-internal-towlower and --with-internal-wcwidth which allows
the system functions for wide-character classification,
case-switching and width (wcwidth and wcswidth) to be replaced by
internal ones. The first has long been used on macOS, AIX (and
Windows) but this enables it to be unselected there and selected
for other platforms (it is the new default on Solaris). The
second is new in this version of R and is selected by default on
macOS and Solaris. The third has long been the default and
remains so as it contains customizations for East Asian
languages.
System versions of these functions are often minimally
implemented (sometimes only for ASCII characters) and may not
cover the full range of Unicode points: for example Solaris (and
Windows) only cover the Basic Multilingual Plane.
* Cairo installations without X11 are more likely to be detected by
configure, when the file-based Cairo graphics devices will be
available but not X11(type = "cairo").
* There is a new configure option --with-static-cairo which is the
default on macOS. This should be used when only static cairo
(and where relevant, Pango) libraries are available.
* Cairo-based graphics devices on platforms without Pango but with
FreeType/FontConfig will make use of the latter for font
selection.
LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
* Configuring with flag --enable-lto=R now also uses LTO when
installing the recommended packages.
* R CMD INSTALL and R CMD SHLIB have a new flag --use-LTO to use
LTO when compiling code, for use with R configured with
--enable-lto=R. For R configured with --enable-lto, they have
the new flag --no-use-LTO.
Packages can opt in or out of LTO compilation _via_ a UseLTO
field in the DESCRIPTION file. (As usual this can be overridden
by the command-line flags.)
BUILDING R on Windows:
* for GCC >= 8, FC_LEN_T is defined in config.h and hence character
lengths are passed from C to Fortran in _inter alia_ BLAS and
LAPACK calls.
* There is a new text file src/gnuwin32/README.compilation, which
outlines how C/Fortran code compilation is organized and
documents new features:
* R can be built with Link-Time Optimization with a suitable
compiler - doing so with GCC 9.2 showed several
inconsistencies which have been corrected.
* There is support for cross-compiling the C and Fortran code
in R and standard packages on suitable (Linux) platforms.
This is mainly intended to allow developers to test later
versions of compilers - for example using GCC 9.2 or 10.x has
detected issues that GCC 8.3 in Rtools40 does not.
* There is experimental support for cross-building R packages
with C, C++ and/or Fortran code.
* The R installer can now be optionally built to support a single
architecture (only 64-bit or only 32-bit).
PACKAGE INSTALLATION:
* The default C++ standard has been changed to C++14 where
available (which it is on all currently checked platforms): if
not (as before) C++11 is used if available otherwise C++ is not
supported.
Packages which specify C++11 will still be installed using C++11.
C++14 compilers may give deprecation warnings, most often for
std::random_shuffle (deprecated in C++14 and removed in C++17).
Either specify C++11 (see 'Writing R Extensions') or modernize
the code and if needed specify C++14. The latter has been
supported since R 3.4.0 so the package's DESCRIPTION would need
to include something like
Depends: R (>= 3.4)
PACKAGE INSTALLATION on Windows:
* R CMD INSTALL and R CMD SHLIB make use of their flag --use-LTO
when the LTO_OPT make macro is set in file etc/${R_ARCH}/Makeconf
or in a personal/site Makevars file. (For details see 'Writing R
Extensions' SS4.5.)
This provides a valuable check on code consistency. It does work
with GCC 8.3 as in Rtools40, but that does not detect everything
the CRAN checks with current GCC do.
PACKAGE INSTALLATION on macOS:
* The default personal library directory on builds with
--enable-aqua (including CRAN builds) now differs by CPU type,
one of
~/Library/R/x86_64/x.y/library
~/Library/R/arm64/x.y/library
This uses the CPU type R (and hence the packages) were built for,
so when a x86_64 build of R is run under Rosetta emulation on an
arm64 Mac, the first is used.
UTILITIES:
* R CMD check can now scan package functions for bogus return
statements, which were possibly intended as return() calls (wish
of PR#17180, patch by Sebastian Meyer). This check can be
activated via the new environment variable
_R_CHECK_BOGUS_RETURN_, true for --as-cran.
* R CMD build omits tarballs and binaries of previous builds from
the top-level package directory. (PR#17828, patch by Sebastian
Meyer.)
* R CMD check now runs sanity checks on the use of LazyData, for
example that a data directory is present and that
LazyDataCompression is not specified without LazyData and has a
documented value. For packages with large LazyData databases
without specifying LazyDataCompression, there is a reference to
the code given in 'Writing R Extensions' SS1.1.6 to test the
choice of compression (as in all the CRAN packages tested a
non-default method was preferred).
* R CMD build removes LazyData and LazyDataCompression fields from
the DESCRIPTION file of packages without a data directory.
ENCODING-RELATED CHANGES:
* The parser now treats \Unnnnnnnn escapes larger than the upper
limit for Unicode points (\U10FFFF) as an error as they cannot be
represented by valid UTF-8.
Where such escapes are used for outputting non-printable
(including unassigned) characters, 6 hex digits are used (rather
than 8 with leading zeros). For clarity, braces are used, for
example \U{0effff}.
* The parser now looks for non-ASCII spaces on Solaris (as
previously on most other OSes).
* There are warnings (including from the parser) on the use of
unpaired surrogate Unicode points such as \uD834. (These cannot
be converted to valid UTF-8.)
* Functions nchar(), tolower(), toupper() and chartr() and those
using regular expressions have more support for inputs with a
marked Latin-1 encoding.
* The character-classification functions used (by default) to
replace the system iswxxxxx functions on Windows, macOS and AIX
have been updated to Unicode 13.0.0.
The character-width tables have been updated to include new
assignments in Unicode 13.0.0.
* The code for evaluating default (extended) regular expressions
now uses the same character-classification functions as the rest
of R (previously they differed on Windows, macOS and AIX).
* There is a build-time option to replace the system's
wide-character wctrans C function by tables shipped with R: use
configure option --with-internal-towlower or (on Windows)
-DUSE_RI18N_CASE in CFLAGS when building R. This may be needed
to allow tolower() and toupper() to work with Unicode characters
beyond the Basic Multilingual Plane where not supported by system
functions (e.g. on Solaris where it is the new default).
* R is more careful when truncating UTF-8 and other multi-byte
strings that are too long to be printed, passed to the system or
libraries or placed into an internal buffer. Truncation will no
longer produce incomplete multibyte characters.
DEPRECATED AND DEFUNCT:
* Function plclust() from the package stats and
package.dependencies(), pkgDepends(), getDepList(),
installFoundDepends(), and vignetteDepends() from package tools
are defunct.
* Defunct functions checkNEWS() and readNEWS() from package tools
and CRAN.packages() from utils have been removed.
* R CMD config CXXCPP is defunct (it was deprecated in R 3.6.2).
* parallel::detectCores() drops support for Irix (retired in 2013).
* The LINPACK argument to chol.default(), chol2inv(),
solve.default() and svd() has been defunct since R 3.1.0. It was
silently ignored up to R 4.0.3 but now gives an error.
* Subsetting/indexing, such as ddd[*] or ddd$x on a DOTSXP
(dot-dot-dot) object ddd has been disabled; it worked by accident
only and was undocumented.
BUG FIXES:
* Many more C-level allocations (mainly by malloc and strdup) are
checked for success with suitable alternative actions.
* Bug fix for replayPlot(); this was turning off graphics engine
display list recording if a recorded plot was replayed in the
same session. The impact of the bug became visible if resize the
device after replay OR if attempted another savePlot() after
replay (empty display list means empty screen on resize or empty
saved plot).
* R CMD check etc now warn when a package exports non-existing S4
classes or methods, also in case of no "methods" presence.
(Reported by Alex Bertram; reproducible example and patch by
Sebastian Meyer in PR#16662.)
* boxplot() now also accepts calls for labels such as ylab, the
same as plot(). (Reported by Marius Hofert.)
* The help page for xtabs() now correctly states that addNA is
setting na.action = na.pass among others. (Reported as PR#17770
by Thomas Soeiro.)
* The R CMD check <pkg> gives a longer and more comprehensible
message when DESCRIPTION misses dependencies, e.g., in Imports:.
(Thanks to the contributors of PR#17179.)
* update.default() now calls the generic update() on the formula to
work correctly for models with extended formulas. (As reported
and suggested by Neal Fultz in PR#17865.)
* The horizontal position of leaves in a dendrogram is now correct
also with center = FALSE. (PR#14938, patch from Sebastian
Meyer.)
* all.equal.POSIXt() no longer warns about and subsequently ignores
inconsistent "tzone" attributes, but describes the difference in
its return value (PR#17277). This check can be disabled _via_
the new argument check.tzone = FALSE as suggested by Sebastian
Meyer.
* as.POSIXct() now populates the "tzone" attribute from its tz
argument when x is a logical vector consisting entirely of NA
values.
* x[[2^31]] <- v now works. (Thanks to the report and patch by
Suharto Anggono in PR#17330.)
* In log-scale graphics, axis() ticks and label positions are now
computed more carefully and symmetrically in their range,
typically providing _more_ ticks, fulfilling wishes in PR#17936.
The change really corresponds to an improved axisTicks() (package
grDevices), potentially influencing grid and lattice, for
example.
* qnorm(<very large negative>, log.p=TRUE) is now correct to at
least five digits where it was catastrophically wrong,
previously.
* sum(df) and similar "Summary"- and "Math"-group member functions
now work for data frames df with logical columns, notably also of
zero rows. (Reported to R-devel by Martin "b706".)
* unsplit() had trouble with tibbles due to unsound use of rep(NA,
len)-indexing, which should use NA_integer_ (Reported to R-devel
by Mario Annau.)
* pnorm(x, log.p = TRUE) underflows to -Inf slightly later.
* show(<hidden S4 generic>) prints better and without quotes for
non-hidden S4 generics.
* read.table() and relatives treated an "NA" column name as missing
when check.names = FALSE PR#18007.
* Parsing strings containing UTF-16 surrogate pairs such as
"\uD834\uDD1E" works better on some (uncommon) platforms.
sprintf("%X", utf8ToInt("\uD834\uDD1E")) should now give "1D11E"
on all platforms.
* identical(x,y) is no longer true for differing DOTSXP objects,
fixing PR#18032.
* str() now works correctly for DOTSXP and related exotics, even
when these are doomed.
Additionally, it no longer fails for lists with a class and
"irregular" method definitions such that e.g. lapply(*) will
necessarily fail, as currently for different igraph objects.
* Too long lines in environment files (e.g. Renviron) no longer
crash R. This limit has been increased to 100,000 bytes.
(PR#18001.)
* There is a further workaround for FreeType giving incorrect
italic font faces with cairo-based graphics devices on macOS.
* add_datalist(*, force = TRUE) (from package tools) now actually
updates an existing data/datalist file for new content. (Thanks
to a report and patch by Sebastian Meyer in PR#18048.)
* cut.Date() and cut.POSIXt() could produce an empty last interval
for breaks = "months" or breaks = "years". (Reported as PR#18053
by Christopher Carbone.)
* Detection of the encoding of 'regular' macOS locales such as
en_US (which is UTF-8) had been broken by a macOS change:
fortunately these are now rarely used with en_US.UTF-8 being
preferred.
* sub() and gsub(pattern, repl, x, *) now keep attributes of x such
as names() also when pattern is NA (PR#18079).
* Time differences ("difftime" objects) get a replacement and a
rep() method to keep "units" consistent. (Thanks to a report and
patch by Nicolas Bennett in PR#18066.)
* The \RdOpts macro, setting defaults for \Sexpr options in an Rd
file, had been ineffective since R 2.12.0: it now works again.
(Thanks to a report and patch by Sebastian Meyer in PR#18073.)
* mclapply and pvec no longer accidentally terminate parallel
processes started before by mcparallel or related calls in
package parallel (PR#18078).
* grep and other functions for evaluating (extended) regular
expressions handle in Unicode also strings not explicitly flagged
UTF-8, but flagged native when running in UTF-8 locale.
* Fixed a crash in fifo implementation on Windows (PR#18031).
* Binary mode in fifo on Windows is now properly detected from
argument open (PR#15600, PR#18031).
# dplyr 1.0.6
* `add_count()` is now generic (#5837).
* `if_any()` and `if_all()` abort when a predicate is mistakingly used
as `.cols=` (#5732).
* Multiple calls to `if_any()` and/or `if_all()` in the same
expression are now properly disambiguated (#5782).
* `filter()` now inlines `if_any()` and `if_all()` expressions. This
greatly improves performance with grouped data frames.
* Fixed behaviour of `...` in top-level `across()` calls (#5813, #5832).
* `across()` now inlines lambda-formulas. This is slightly more performant and
will allow more optimisations in the future.
* Fixed issue in `bind_rows()` causing lists to be incorrectly transformed as
data frames (#5417, #5749).
* `select()` no longer creates duplicate variables when renaming a variable
to the same name as a grouping variable (#5841).
* `dplyr_col_select()` keeps attributes for bare data frames (#5294, #5831).
* Fixed quosure handling in `dplyr::group_by()` that caused issues with extra
arguments (tidyverse/lubridate#959).
* Removed the `name` argument from the `compute()` generic (@ianmcook, #5783).
* row-wise data frames of 0 rows and list columns are supported again (#5804).
# dplyr 1.0.5
* Fixed edge case of `slice_sample()` when `weight_by=` is used and there
0 rows (#5729).
* `across()` can again use columns in functions defined inline (#5734).
* Using testthat 3rd edition.
* Fixed bugs introduced in `across()` in previous version (#5765).
* `group_by()` keeps attributes unrelated to the grouping (#5760).
* The `.cols=` argument of `if_any()` and `if_all()` defaults to `everything()`.
# dplyr 1.0.4
* Improved performance for `across()`. This makes `summarise(across())` and
`mutate(across())` perform as well as the superseded colwise equivalents (#5697).
* New functions `if_any()` and `if_all()` (#4770, #5713).
* `summarise()` silently ignores NULL results (#5708).
* Fixed a performance regression in `mutate()` when warnings occur once per
group (#5675). We no longer instrument warnings with debugging information
when `mutate()` is called within `suppressWarnings()`.
# dplyr 1.0.3
* `summarise()` no longer informs when the result is ungrouped (#5633).
* `group_by(.drop = FALSE)` preserves ordered factors (@brianrice2, #5545).
* `count()` and `tally()` are now generic.
* Removed default fallbacks to lazyeval methods; this will yield
better error messages when you call a dplyr function with the wrong
input, and is part of our long term plan to remove the deprecated
lazyeval interface.
* `inner_join()` gains a `keep` parameter for consistency with the other
mutating joins (@patrickbarks, #5581).
* Improved performance with many columns, with a dynamic data mask using active
bindings and lazy chops (#5017).
* `mutate()` and friends preserves row names in data frames once more (#5418).
* `group_by()` uses the ungrouped data for the implicit mutate step (#5598).
You might have to define an `ungroup()` method for custom classes.
For example, see https://github.com/hadley/cubelyr/pull/3.
* `relocate()` can rename columns it relocates (#5569).
* `distinct()` and `group_by()` have better error messages when the
mutate step fails (#5060).
* Clarify that `between()` is not vectorised (#5493).
* Fixed `across()` issue where data frame columns would could not be referred to
with `all_of()` in the nested case (`mutate()` within `mutate()`) (#5498).
* `across()` handles data frames with 0 columns (#5523).
* `mutate()` always keeps grouping variables, unconditional to `.keep=` (#5582).
* dplyr now depends on R 3.3.0
# dplyr 1.0.2
* Fixed `across()` issue where data frame columns would mask objects referred to
from `all_of()` (#5460).
* `bind_cols()` gains a `.name_repair` argument, passed to
`vctrs::vec_cbind()` (#5451)
* `summarise(.groups = "rowwise")` makes a rowwise data frame even if
the input data is not grouped (#5422).
# dplyr 1.0.1
* New function `cur_data_all()` similar to `cur_data()` but includes
the grouping variables (#5342).
* `count()` and `tally()` no longer automatically weights by column `n` if
present (#5298). dplyr 1.0.0 introduced this behaviour because of Hadley's
faulty memory. Historically `tally()` automatically weighted and `count()`
did not, but this behaviour was accidentally changed in 0.8.2 (#4408) so that
neither automatically weighted by `n`. Since 0.8.2 is almost a year old,
and the automatically weighting behaviour was a little confusing anyway,
we've removed it from both `count()` and `tally()`.
Use of `wt = n()` is now deprecated; now just omit the `wt` argument.
* `coalesce()` now supports data frames correctly (#5326).
* `cummean()` no longer has off-by-one indexing problem (@cropgen, #5287).
* The call stack is preserved on error. This makes it possible to `recover()`
into problematic code called from dplyr verbs (#5308).
These produce poor code and it's always better to use the CPU-specific
intrinsics instead, which we already do on platforms where the test
suite doesn't fail.
Those cmake config files are not useful for us and they are incorrect
for the upcoming 64-bit-index variants. Also, we could switch back
to the Makefile build from cmake in future. Let's treat the question of
CMake as implementation detail of the packages.
The actual use is via mk/blas.bl3 in pkgsrc and pkg-config. There isn't
even added value in these files, were they to be correct. CMake builds
can use pkg-config just fine.
Changed in xts 0.12.1:
o Various function could change the tclass of xts objects. This would happen
in calls to reclass(), period.apply(), and for logical operations on
POSIXct indexes. Thanks to Tom Andrews for the report and testing, and to
Panagiotis Cheilaris for contributing test cases (#322, #323).
o plot.xts() now supports y-axis labels via 'ylab'. Thanks to Jasen Mackie
for the suggestion and PR (#333, #334).
o The API header has been updated to fix the signatures of do_merge_xts() and
is_xts, which did not return a SEXP as required of functions callable by
.Call(). Thanks to Tomas Kalibera for the report (#317), and Dirk
Eddelbuettel for the PR (#337). This is a breaking change, but is required
to avoid the potential for a segfault.
o Michael Chirico added an internal isUTC() function to recognize many UTC-
equivalent time zones (#319).
o first() now operates correctly on non-xts objects when 'n = -1'. Previously
it would always return the last two values. Thanks to GitHub user vxg20
for the report (#325).
o The .xts() constructor would create an xts object with row names if 'x' had
row names. This shouldn't happen, because xts objects do not have or
support row names (#298).
o Claymore Marshall added many examples of time-of-day subsetting to
?subset.xts. He also fixed a bug in time-of-day subsetting where subsetting
by hour only returned wrong results (#304, #326, #328).
Changed in xts 0.12-0:
o All the index-attributes have been removed from the xts object and are now
only attached to the index itself (#245). We took great care to maintain
backward compatibility, and throw warnings when deprecated functions are
called and when index-attributes are found on the xts object. But there
still may be some breaking changes lurking in edge cases.
o @SamoPP found one edge case (#297) where an error was thrown when index()
was called on an xts object with an index that had no tclass attribute.
o ...which led Joshua to find that the index setting functions did not
always copy index attributes (#305).
o Several binary operations (e.g. +, -, !=, <, etc.) on variations of
uncommon xts objects with other xts, matrix, or vector objects, could
result in malformed xts objects (#295). Some examples of the types of
uncommon xts objects: no dim attribute, zero-width, zero-length.
o Calling as.matrix() on an xts object without a dim attribute no longer
throws an error (#294).
o merge.xts() now honors check.names = FALSE (#293).
o The possible values for major.ticks, minor.ticks, and grid.ticks.on in the
Details section of ?plot.xts have been corrected. Thanks to Harvey Smith
(@harvey131) for the report and patch (#291).
o as.zoo.xts() is now only registered for zoo versions prior to 1.8-5. Methods
to convert an object to another class should reside in the package that
implements the target class. Thanks to Kurt Hornik for the report (#287).
o .parseISO8601() no longer has a potential length-1 logical error. Thanks to
Kurt Hornik for the report (#280).
o endpoints() now honors k > 0 when on = "quarters". Thanks to @alkment for
the report (#279).
o Performance for the period.XYZ() functions (sum, prod, min, max) is much
faster (#278). Thanks to Harvey Smith (@harvey131) for the report and
examples.
o merge.xts() now creates shorter column names when passed unnamed objects.
This is now consistent with zoo (#248).
o Time-of-day performance is ~200x faster, thanks to StackOverflow
user3226167 (#193).
Changes in Version 1.8-9
o Added a basic boxplot(x, ...) method for zoo objects that simply calls
boxplot(coredata(x), ...).
o Bug fix in [.zoo and [<-.zoo where indexing with matrices did not
work correctly anymore in R 4.x.y because "matrix" objects now additionally
inherit from "array" objects. (Reported by Bill Cunliffe.)
o Improved internal functionality in na.spline.default() in the same way
na.approx.default() was enhanced in zoo 1.7-14 and 1.7-13. One difference
is that while na.approx() requires at least two non-NA observations,
na.spline() just needs one non-NA observation (using a constant to
interpolate in that case).
o If the FUN in rollapply() returns a matrix or data.frame with more than
one row per element/time point, then this is flattened now so that the
result is again a matrix with one row per element/time point.
o merge.zoo() now handles the case of all indexes being integer or numeric
by coercing the integer indexes to numeric (reported by Simone Giannerini).
o zooreg(x) now allows to create an integer index if start (and end, if any)
are integer and the implied deltat is not numerically different from an
integer value.
Changes in Version 1.8-8
o diff.zoo(x, arithmetic = FALSE) now also works if x contains negative
data.
o merge.zoo() now handles the combination of Date and numeric indexes
explicitly to work around the new behavior of c.Date() in R >= 4.1.0.
Changes in Version 1.8-7
o Added scale_type() methods for yearmon/yearqtr to facilitate ggplot2
visualizations of zoo series with yearmon/yearqtr time index (suggested
by Brian Diggs). This requires at least ggplot2 3.0.0.
o In merge.zoo() "character" columns are now processed in the same way
as "logical" columns.
o Replaced the "fruitohms" example in the "zoo" vignette because the
corresponding "DAAG" package is not actively maintained on CRAN anymore.
Instead the "Journals" data from the "AER" package is used.
# forcats 0.5.1
* Re-license as MIT (#277).
* `fct_lump_n()` no longer uses a partial argument name (@malcolmbarrett, #276).

All `fct_lump_()` functions check their inputs more carefully
(@robinson_es, #169)
* `fct_reorder2()` gains a helper function `first2()`, that sorts `.y` by the
first value of `.x` (@jtr13).

- `tbl[FALSE, "column"] <- x` adds new column again (#846).
## Features
- Importing pillar 1.5.0, cli and crayon are now suggested packages (#475).
- `size_sum()` is now reexported from pillar (#850, @topepo).
- `as_tibble()` hints more often to use the `.name_repair` argument if column names are invalid (#855).
- `as_tibble.table()` mentions `.name_repair` argument in the error message (#839).
## Internal
- Remove compatibility code for pillar < 1.5.0 (#861).
- Moved most functions to the "stable" lifecycle (#860).
# tibble 3.0.6
- `vec_ptype_abbr.tbl_df()` and `type_sum.tbl_df()` now uses the name of the topmost class for subclasses of `"tbl_df"` (#843).
- Ignore errors in `formats.Rmd` vignette.
- Avoid tidy evaluation in pillar compatibility code.
# tibble 3.0.5
- Use testthat edition 3, compatible with testthat 3.0.1 (#827, #832).
# tibble 3.0.4
## Compatibility
- Establish compatibility with upcoming pillar 1.5.0 (#818).
- `tbl_sum()` shows "data frame" instead of "tibble" for objects inheriting from `"tbl"` but not `"tbl_df"` (#818).
- Register `format.tbl()` and `print.tbl()` methods only if pillar doesn't (#816).

- `add_row(df)` adds an empty row again (#809, @DavisVaughan).
# tibble 3.0.3
- Fix test compatibility with rlang 0.4.7.

# tibble 3.0.2
## Bug fixes
- `[[` works with classed indexes again, e.g. created with `glue::glue()` (#778).
- `add_column()` works without warning for 0-column data frames (#786).
- `tribble()` now better handles named inputs (#775) and objects of non-vtrs classes like `lubridate::Period` (#784) and `formattable::formattable` (#785).
## Performance
- Subsetting and subassignment are faster (#780, #790, #794).
- `is.null()` is preferred over `is_null()` for speed.
- Implement continuous benchmarking (#793).
## Compatibility
- `is_vector_s3()` is no longer reexported from pillar (#789).
# tibble 3.0.1

## Bug fixes
- More soft-deprecation warnings are actually visible.
- If `.name_repair` is a function, no repair messages are shown (#763).
- Remove superseded signal for `as_tibble.list()`, because `as_tibble_row()` only works for size 1.
## Enhancements
- `as_tibble(validate = )` now always triggers a deprecation warning.
- Subsetting and subassignment of rows with one-column matrices work again, with a deprecation warning (#760).
- Attempts to update a tibble row with an atomic vector give a clearer error message. Recycling message for subassignment appears only if target size is != 1.
- Tweak title of "Invariants" vignette.
# tibble 3.0.0
## Major breaking changes
- Subset assignment ("subassignment") and also subsetting has become stricter. Symptoms:
- Error: No common type for ...
- Error: Assigned data `...` must be compatible with ...
- `i` must have one dimension, not 2
- Error: Lossy cast from ... to ...
The "invariants" article at https://tibble.tidyverse.org/dev/articles/invariants.html describes the invariants that the operations follow in tibble, and the most important differences to data frames. We tried to make subsetting and subassignment as safe as possible, so that errors are caught early on, while introducing as little friction as possible.
- List classes are no longer automatically treated as vectors. Symptoms:
- Error: All columns in a tibble must be vectors
- Error: Expected a vector, not a `...` object
If you implement a class that wraps a list as S3 vector, you need to include `"list"` in the class:
```r
structure(x, class = c("your_s3_class", "list"))
```
Alternatively, implement a `vec_proxy()` method as described in https://vctrs.r-lib.org/reference/vec_data.html, or construct your class with `list_of()`.
- Added experimental support for inner names for all columns, of the form `tibble(a = c(b = 1))`. Inner names are no longer stripped when creating a tibble. They are maintained for slicing operations but not yet updated when assigning with a row subscript. This is a change that may break existing comparison tests that don't expect names in columns (#630). Symptoms:
- "names for target but not for current" when comparing
## Breaking changes
- `tibble()` now splices anonymous data frames, `tibble(tibble(a = 1), b = a)` is equivalent to `tibble(a = 1, b = a)`. This means that `tibble(iris)` now has five columns, use `tibble(iris = iris)` if the intention is to create a packed data frame (#581).
- The `name-repair` help topic is gone, refer to `?vctrs::vec_as_names` instead.
- `expression()` columns are converted to lists as a workaround for lacking support in vctrs (#657).
- `tribble()` is now stricter when combining values. All values in a column must be compatible, otherwise an error occurs (#204). The criteria for wrapping in a list column are now based on vctrs principles: non-vectors or vectors with `vctrs::vec_size()` unequal 1 are wrapped in lists.
- `$` warns unconditionally if column not found, `[[` doesn't warn.
- `add_row()` now uses `vctrs::vec_rbind()` under the hood, this means that all columns are combined with `vctrs::vec_c()`. In particular, factor columns will be converted to character if one of the columns is a character column.
## Soft deprecations
- Soft-deprecate `subclass` argument to `new_tibble()`.
- Soft-deprecate `as_tibble()` without arguments (#683).
- Preparing to move `glimpse()` and `tbl_sum()` to the pillar package. If your package implements these methods, please import the generics from pillar as soon as they become available there.
## Features
- Internals now make heavy use of the vctrs package, following most of the invariants defined there. Name repair is the responsibility of vctrs now (#464).
- All errors emitted directly by the package inherit from the `"tibble_error"` and `"rlang_error"` classes. In some cases, `"vctrs_error"` errors may be passed through. The exact subclass is subject to change.
Example: `tibble(a = quote(b))` raises an error that inherits from `"tibble_error_column_must_be_vector"`, `"tibble_error"` and `"rlang_error"`, and from `"error"` and `"condition"` like all errors. Do not rely on the wording of `"tibble_error_column_must_be_vector"`, this is likely to change.
Use the following pattern to catch errors emitted by tibble:
```r
tryCatch(
your_code(),
tibble_error = function(cnd) {
}
)
```
- New `tibble_row()` constructs tibbles that have exactly one row, or fails. Non-vector objects are automatically wrapped in a list, vectors (including lists) must have length one (#205).
- New `as_tibble_row()` and `as_tibble_col()` convert a bare vector to a one-row or one-column tibble, respectively. `as_tibble_col()` also works for non-bare vectors. Using `as_tibble()` for bare vectors is superseded (#447).
- `as_tibble.data.frame()` uses implicit row names if asked to create a column from row names. This allows lossless direct conversion of matrices with row names to tibbles (#567, @stufield).
- Implement `str.tbl_df()` (#480).
- `tribble()` now returns columns with `"unspecified"` type for 0-row tibbles.
- `add_row()` and `add_column()` now restore attributes to avoid errors when appending to sf objects or other tibble subclasses (#662).
- `add_column()` gains `.name_repair` argument. If not given, `.data` must have unique columns, with a deprecation message.
- Allow `POSIXlt` columns, they are now better supported by dplyr and other tools thanks to vctrs (#626).
- `tibble()` ignores NULL arguments, named or unnamed (#580).
- `view()` works for remote data sources by applying the same strategy as `print()` and `glimpse()`. The maximum number of rows in this case can be specified using the new `n` argument, by default it is taken from the new `"tibble.view_max"` option (#695).
## Output
- Formatting dimensions never uses scientific notation.
- `glimpse()` uses "Rows" and "Columns" instead of "Variables" and "Observations", because we're not sure if the data is tidy here (#614).
- `view()` now uses the created (or passed) title argument (#610, @xvrdm).
## Performance
- Construction and subsetting of large data frames is faster now (#717, @romainfrancois).
## Internal
- Import lifecycle package (#669).
- `new_tibble()` removes redundant subclasses from the `"class"` attribute.
- Using classed conditions. All classes start with `"tibble_error_"` and also contain `"tibble_error"` (#659).
- The magrittr pipe `%>%` is reexported.
# 1.1.1
* Fix spurious zero fractions in `pretty_bytes()` when formatting
vectors of sizes (#23).
# 1.1.0
* `pretty_dt()`, `pretty_ms()` and `pretty_sec()` now handle `NA` values
properly, and return `NA_character_` for them (#10, @petermeissner).
* `pretty_bytes()` now formats quantities just below the units better.
E.g. 1MB - 1B is formatted as `"1 MB"` instead of `""1000 kB"` (#18).
* `pretty_bytes()` now has multiple styles. In particular, a fixed width
style is useful for progress bars. Another style avoids the left-padding
with spaces.
* The new low level `compute_bytes()` function can be used to create
custom formatters for bytes.
This also affects py-{ailment,archinfo,cle,pyvex,claripy}, which get updated to
the same version at the same time.
I could not find any specific release notes or changelog.
The whole list of changes can be found at:
https://github.com/angr/angr/compare/v9.0.4378...v9.0.7833.
The upcoming lapack64 needs the library name liblapack64, the
variable for that was missing in the patch. This does not change
the build of math/lapack itself.
* What is new in gsl-2.6:
** add BLAS calls for the following functions:
- gsl_vector_memcpy
- gsl_vector_scale
- gsl_matrix_memcpy
- gsl_matrix_transpose_memcpy
- gsl_matrix_tricpy
- gsl_matrix_transpose_tricpy
** deprecated functions gsl_linalg_complex_householder_hm and
gsl_linalg_complex_householder_mh
** add unit tests for gsl_linalg_symmtd and gsl_linalg_hermtd
** multilarge TSQR algorithm has been converted to use the new Level 3 QR decomposition
** nonlinear least squares Cholesky solver now uses the new Level 3 BLAS
method; the old modified Cholesky solver is still available under
gsl_multifit_nlinear_solver_mcholesky and gsl_multilarge_nlinear_solver_mcholesky
** implemented Level 3 BLAS versions of several linear algebra routines:
- Triangular matrix inversion
- Cholesky decomposition and inversion (real and complex)
- LU decomposition and inversion (real and complex)
- QR decomposition (courtesy of Julien Langou)
- Generalized symmetric/hermitian eigensystem reduction to standard form
** removed deprecated function gsl_linalg_hessenberg()
** renamed gsl_interp2d_eval_e_extrap() to gsl_interp2d_eval_extrap_e()
to match documentation (reported by D. Lebrun-Grandie)
** renamed some of the gsl_sf_hermite functions to be more consistent
with rest of the library, and deprecated old function names
** updated gsl_sf_hermite_func() to use a newer algorithm
due to B. Bunck which is more stable for large x; also added
gsl_sf_hermite_func_fast() which uses the faster Cauchy integral
algorithm in the same paper by Bunck
** add gsl_vector_axpby()
** add un-pivoted LDLT decomposition and its banded
variant (gsl_linalg_ldlt_* and gsl_linalg_ldlt_band_*)
** add binary search tree module (gsl_bst); based on GNU libavl
** remove -u flag to gsl-histogram
** updated spmatrix module
- added routines and data structures for all types (float,uint,char,...)
- added gsl_spmatrix_scale_columns() and gsl_spmatrix_scale_rows()
- added gsl_spmatrix_add_to_dense()
- more efficient reallocation of COO/triplet matrices (no longer rebuilds binary tree)
- enhanced test suite
- added gsl_spmatrix_min_index()
** add routines for banded Cholesky decomposition (gsl_linalg_cholesky_band_*)
** documented gsl_linalg_LQ routines and added gsl_linalg_LQ_lssolve()
This updates octave and also gets some more recommened dependencies in,
namely qrupdate and Mesalib (for osmesa) and gl2ps as well as the
qscintilla editor. The glpk option is on by default again.
This version of octave comes rather close to a standard build, with
optimzied BLAS and GUI fluff. We are still missing SuiteSparse and
SUNDIALS solvers, see
https://octave.org/doc/v6.2.0/External-Packages.html
PortAudio should also be considered, and LLVM be watched if that
experimental JIT settles in.
Upstream changes since 5.x:
Summary of important user-visible changes for version 6.1.0 (2020-11-26):
------------------------------------------------------------------------
### General improvements
- The `intersect`, `setdiff`, `setxor`, `union`, and `unique` functions
accept a new sorting option `"stable"` which will return output values
in the same order as the input, rather than in ascending order.
- Complex RESTful web services can now be accessed by the `webread` and
`webwrite` functions alongside with the `weboptions` structure. One
major feature is the support for cookies to enable RESTful
communication with the web service.
Additionally, the system web browser can be opened by the `web`
function.
- The `linspace` function now produces symmetrical sequences when the
endpoints are symmetric. This is more intuitive and also compatible
with recent changes made in Matlab R2019b.
- The underlying algorithm of the `rand` function has been changed.
For single precision outputs, the algorithm has been fixed so that it
produces values strictly in the range (0, 1). Previously, it could
occasionally generate the right endpoint value of 1 (See bug #41742).
In addition, the new implementation uses a uniform interval between
floating point values in the range (0, 1) rather than targeting a
uniform density (# of random integers / length along real number
line).
- Numerical integration has been improved. The `quadv` function has
been re-written so that it can compute integrands of periodic
functions. At the same time, performance is better with ~3.5X fewer
function evaluations required. A bug in `quadgk` that caused complex
path integrals specified with `"Waypoints"` to occasionally be
calculated in the opposite direction was fixed.
- The `edit` function option `"editinplace"` now defaults to `true` and
the option `"home"` now defaults to the empty matrix `[]`. Files will
no longer be copied to the user's HOME directory for editing. The old
behavior can be restored by setting `"editinplace"` to `false` and
`"home"` to `"~/octave"`.
- The `format` command supports two new options: `uppercase` and
`lowercase` (default). With the default, print a lowercase 'e' for
the exponent character in scientific notation and lowercase 'a-f' for
the hex digits representing 10-15. With `uppercase`, print 'E' and
'A-F' instead. The previous uppercase formats, `E` and `G`, no longer
control the case of the output.
Additionally, the `format` command can be called with multiple options
for controlling the format, spacing, and case in arbitrary order.
For example:
format long e uppercase loose
Note, in the case of multiple competing format options the rightmost
one is used, and, in case of an error, the previous format remains
unchanged.
- L-value references (e.g., increment (++), decrement (--), and all
in-place assignment operators (+=, -=, *=, /=, etc.)) are no longer
allowed in anonymous functions.
- New warnings have been added about questionable uses of the colon ':'
range operator. Each has a new warning ID so that it can be disabled
if desired.
> `Octave:colon-complex-argument` : when any arg is complex
> `Octave:colon-nonscalar-argument` : when any arg is non-scalar
- The `regexp` and related functions now correctly handle and *require*
strings in UTF-8 encoding. As with any other function that requires
strings to be encoded in Octave's native encoding, you can use
`native2unicode` to convert from your preferred locale. For example,
the copyright symbol in UTF-8 is `native2unicode (169, "latin1")`.
- The startup file `octaverc` can now be located in the platform
dependent location for user local configuration files (e.g.,
${XDG_CONFIG_HOME}/octave/octaverc on Unix-like operating systems or
%APPDATA%\octave\octaverc on Windows).
- `pkg describe` now lists dependencies and inverse dependencies
(i.e., other installed packages that depend on the package in
question).
- `pkg test` now tests all functions in a package.
- When unloading a package, `pkg` now checks if any remaining loaded
packages depend on the one to be removed. If this is the case `pkg`
aborts with an explanatory error message. This behavior can be
overridden with the `-nodeps` option.
- The command
dbstop in CLASS at METHOD
now works to set breakpoints in classdef constructors and methods.
#### Graphics backend
- The use of Qt4 for graphics and the GUI is deprecated in Octave
version 6 and no further bug fixes will be made. Qt4 support will be
removed completely in Octave version 7.
- The `legend` function has been entirely rewritten. This fixes a
number of historical bugs, and also implements new properties such as
`"AutoUpdate"` and `"NumColumns"`. The gnuplot toolkit---which is no
longer actively maintained---still uses the old legend function.
- The `axis` function was updated which resolved 10 bugs affecting
axes to which `"equal"` had been applied.
- Graphic primitives now accept a color property value of `"none"`
which is useful when a particular primitive needs to be hidden
(for example, the Y-axis of an axes object with `"ycolor" = "none"`)
without hiding the entire primitive `"visibility" = "off"`.
- A new property `"FontSmoothing"` has been added to text and axes
objects that controls whether anti-aliasing is used during the
rendering of characters. The default is `"on"` which produces smooth,
more visually appealing text.
- The figure property `"windowscrollwheelfcn"`is now implemented.
This makes it possible to provide a callback function to be executed
when users manipulate the mouse wheel on a given figure.
- The figure properties `"pointer"`, `"pointershapecdata"`, and
`"pointershapehotspot"` are now implemented. This makes it possible
to change the shape of the cursor (pointer in Matlab-speak) displayed
in a plot window.
- The figure property `"paperpositionmode"` now has the default `"auto"`
rather than `"manual"`. This change is more intuitive and is
Matlab compatible.
- The appearance of patterned lines `"LineStyle" = ":"|"--"|"-."` has
been improved for small widths (`"LineWidth"` less than 1.5 pixels)
which is a common scenario.
- Printing to EPS files now uses a tight bounding box (`"-tight"`
argument to print) by default. This makes more sense for EPS
files which are normally embedded within other documents, and is
Matlab compatible. If necessary use the `"-loose"` option to
reproduce figures as they appeared in previous versions of Octave.
- The following print devices are no longer officially supported: cdr,
corel, aifm, ill, cgm, hpgl, mf and dxf. A warning will be thrown
when using those devices, and the code for supporting those formats
will eventually be removed from a future version of Octave.
- The placement of text subscripts and superscripts has been
re-engineered and now produces visually attractive results similar to
Latex.
### Matlab compatibility
- The function `unique` now returns column index vectors for the second
and third outputs. When duplicate values are present, the default
index to return is now the `"first"` occurrence. The previous Octave
behavior, or Matlab behavior from releases prior to R2012b, can be
obtained by using the `"legacy"` flag.
- The function `setdiff` with the `"rows"` argument now returns Matlab
compatible results. The previous Octave behavior, or Matlab behavior
from releases prior to R2012b, can be obtained by using the `"legacy"`
flag.
- The functions `intersect`, `setxor`, and `union` now accept a
`"legacy"` flag which changes the index values (second and third
outputs) as well as the orientation of all outputs to match Matlab
releases prior to R2012b.
- The function `streamtube` is Matlab compatible and plots tubes along
streamlines which are scaled by the vector field divergence. The
Octave-only extension `ostreamtube` can be used to visualize the flow
expansion and contraction of the vector field due to the local
crossflow divergence.
- The interpreter now supports handles to nested functions.
- The graphics properties `"LineWidth"` and `"MarkerSize"` are now
measured in points, *not* pixels. Compared to previous versions
of Octave, some lines and markers will appear 4/3 larger.
- The meta.class property "SuperClassList" has been renamed
"Superclasslist" for Matlab compatibility. The original name will
exist as an alias until Octave version 8.1.
- Inline functions created by the function `inline` are now of type
"inline" when interrogated with the `class` function. In previous
versions of Octave, the class returned was "function_handle". This
change is Matlab compatible. Inline functions are deprecated in
both Matlab and Octave and support may eventually be removed.
Anonymous functions can be used to replace all instances of inline
functions.
- The function `javaaddpath` now prepends new directories to the
existing dynamic classpath by default. To append them instead, use
the new `"-end"` argument. Multiple directories may now be specified
in a cell array of strings.
- An undocumented function `gui_mainfcn` has been added, for compatibility
with figures created with Matlab's GUIDE.
- Several validator functions of type `mustBe*` have been added. See
the list of new functions below.

It is wrong to disable OpenMP and this setting does nothing anyway.
Maybe it did in the past. Now, the build tries to use OpenMP if
possible and this is the right thing to do.
Repeat: This change doesn't affect the build at all since that variable
is not checked (since some time?).
(pkgsrc changes)
- Add TEST_DEPENDS+, but still one missing is there
(upstream changes)
# vctrs 0.3.8
* Compatibility with next version of rlang.
# vctrs 0.3.7
* `vec_ptype_abbr()` gains arguments to control whether to indicate
named vectors with a prefix (`prefix_named`) and indicate shaped
vectors with a suffix (`suffix_shape`) (#781, @krlmlr).
* `vec_ptype()` is now an optional _performance_ generic. It is not necessary
to implement, but if your class has a static prototype, you might consider
implementing a custom `vec_ptype()` method that returns a constant to
improve performance in some cases (such as common type imputation).
* New `vec_detect_complete()`, inspired by `stats::complete.cases()`. For most
vectors, this is identical to `!vec_equal_na()`. For data frames and
matrices, this detects rows that only contain non-missing values.
* `vec_order()` can now order complex vectors (#1330).
* Removed dependency on digest in favor of `rlang::hash()`.
* Fixed an issue where `vctrs_rcrd` objects were not being proxied correctly
when used as a data frame column (#1318).
* `register_s3()` is now licensed with the "unlicense" which makes it very
clear that it's fine to copy and paste into your own package
(@maxheld83, #1254).
# vctrs 0.3.6
* Fixed an issue with tibble 3.0.0 where removing column names with
`names(x) <- NULL` is now deprecated (#1298).
* Fixed a GCC 11 issue revealed by CRAN checks.
# vctrs 0.3.5
* New experimental `vec_fill_missing()` for filling in missing values with
the previous or following value. It is similar to `tidyr::fill()`, but
also works with data frames and has an additional `max_fill` argument to
limit the number of sequential missing values to fill.
* New `vec_unrep()` to compress a vector with repeated values. It is very
similar to run length encoding, and works nicely alongside `vec_rep_each()`
as a way to invert the compression.
* `vec_cbind()` with only empty data frames now preserves the common size of
the inputs in the result (#1281).
* `vec_c()` now correctly returns a named result with named empty inputs
(#1263).
* vctrs has been relicensed as MIT (#1259).
* Functions that make comparisons within a single vector, such as
`vec_unique()`, or between two vectors, such as `vec_match()`, now
convert all character input to UTF-8 before making comparisons (#1246).
* New `vec_identify_runs()` which returns a vector of identifiers for the
elements of `x` that indicate which run of repeated values they fall in
(#1081).
* Fixed an encoding translation bug with lists containing data frames which
have columns where `vec_size()` is different from the low level
`Rf_length()` (#1233).
# vctrs 0.3.4
* Fixed a GCC sanitiser error revealed by CRAN checks.
# vctrs 0.3.3
* The `table` class is now implemented as a wrapper type that
delegates its coercion methods. It used to be restricted to integer
tables (#1190).
* Named one-dimensional arrays now behave consistently with simple
vectors in `vec_names()` and `vec_rbind()`.
* `new_rcrd()` now uses `df_list()` to validate the fields. This makes
it more flexible as the fields can now be of any type supported by
vctrs, including data frames.
* Thanks to the previous change the `[[` method of records now
preserves list fields (#1205).
* `vec_data()` now preserves data frames. This is consistent with the
notion that data frames are a primitive vector type in vctrs. This
shouldn't affect code that uses `[[` and `length()` to manipulate
the data. On the other hand, the vctrs primitives like `vec_slice()`
will now operate rowwise when `vec_data()` returns a data frame.
* `outer` is now passed unrecycled to name specifications. Instead,
the return value is recycled (#1099).
* Name specifications can now return `NULL`. The names vector will
only be allocated if the spec function returns non-`NULL` during the
concatenation. This makes it possible to ignore outer names without
having to create an empty names vector when there are no inner
names:
```
zap_outer_spec <- function(outer, inner) if (is_character(inner)) inner
# `NULL` names rather than a vector of ""
names(vec_c(a = 1:2, .name_spec = zap_outer_spec))
#> NULL
# Names are allocated when inner names exist
names(vec_c(a = 1:2, c(b = 3L), .name_spec = zap_outer_spec))
#> [1] "" "" "b"
```
* Fixed several performance issues in `vec_c()` and `vec_unchop()`
with named vectors.
* The restriction that S3 lists must have a list-based proxy to be considered
lists by `vec_is_list()` has been removed (#1208).
* New performant `data_frame()` constructor for creating data frames in a way
that follows tidyverse semantics. Among other things, inputs are recycled
using tidyverse recycling rules, strings are never converted to factors,
list-columns are easier to create, and unnamed data frame input is
automatically spliced.
* New `df_list()` for safely and consistently constructing the data structure
underlying a data frame, a named list of equal-length vectors. It is useful
in combination with `new_data_frame()` for creating user-friendly
constructors for data frame subclasses that use the tidyverse rules for
recycling and determining types.
* Fixed performance issue with `vec_order()` on classed vectors which
affected `dplyr::group_by()` (tidyverse/dplyr#5423).
* `vec_set_names()` no longer alters the input in-place (#1194).
* New `vec_proxy_order()` that provides an ordering proxy for use in
`vec_order()` and `vec_sort()`. The default method falls through to
`vec_proxy_compare()`. Lists are special cased, and return an integer
vector proxy that orders by first appearance.
* List columns in data frames are no longer comparable through `vec_compare()`.
* The experimental `relax` argument has been removed from
`vec_proxy_compare()`.
Ellipsis 0.3.2
* Compatibility with next version of rlang.
* Changed license to MIT (#39).

v0.18.2 (19 May 2021)
---------------------
This release reverts a regression in xarray's unstacking of dask-backed arrays.
v0.18.1 (18 May 2021)
---------------------
This release is intended as a small patch release to be compatible with the new
2021.5.0 ``dask.distributed`` release. It also includes a new
``drop_duplicates`` method, some documentation improvements, the beginnings of
our internal Index refactoring, and some bug fixes.
New Features
- Implement :py:meth:`DataArray.drop_duplicates`
to remove duplicate dimension values (:pull:`5239`).
- Allow passing ``combine_attrs`` strategy names to the ``keep_attrs`` parameter of
:py:func:`apply_ufunc` (:pull:`5041`)
- :py:meth:`Dataset.interp` now allows interpolation with non-numerical datatypes,
such as booleans, instead of dropping them. (:issue:`4761` :pull:`5008`).
- Raise more informative error when decoding time variables with invalid reference dates.
(:issue:`5199`, :pull:`5288`).
Bug fixes
- Opening netCDF files from a path that doesn't end in ``.nc`` without supplying
an explicit ``engine`` works again (:issue:`5295`), fixing a bug introduced in
0.18.0.
Documentation
- Clean up and enhance docstrings for the :py:class:`DataArray.plot` and ``Dataset.plot.*``
families of methods (:pull:`5285`).
- Explanation of deprecation cycles and how to implement them added to contributors
guide. (:pull:`5289`)

-Estimation/rounding for final results
-Lex special symbols as one token
-Basic rounding for calculus functions
-Higher order derivatation
-Improved accuracy for derivation
-Basics of derivation
-Created 'Identifier' struct that contains prime count and name

-kalk: Fixed type error in kalk_num/regular.rs
-Trimming trailing zeroes for non-rug numbers
-Fixed xy^z precedence, from (xy)^2 to x(y^2)
the package previously used PKG_OPTIONS for this, but PKG_OPTIONS
are harmful in the case that they effect the resulting ABI of
library packages. this way, things that actually need fftwl and fftwq
can depend on these sub-packages.
this also fixes fftwq on NetBSD by making it pull in libquadmath.
another thing about PKG_OPTIONS for library components is that
they mean certain components don't get tested...
This was lost on the recent rework of the patches:
On NetBSD.
In PKGSRC_FORTRAM=gfortran case, libcblas has no RPATH=/usr/pkg/gccXX/lib
and libgfortran and libquadmath are not found.
In PKGSRC_FORTRAN=g95 case, libcblas has no
RPATH=/usr/pkg/lib/gcc-lib/x86_64--netbsd/4.1.2 and libf95 is not found.
Use Fortran compiler as linker instread of C compiler to fix link.

- Performance improvement in :meth:`pd.isin` for inputs with more than 1e6 elements (:issue:`36611`)
- Performance improvement for :meth:`DataFrame.__setitem__` with list-like indexers (:issue:`37954`)

Changes from 2.7.2 to 2.7.3
---------------------------
- Pinned Numpy versions to minimum supported version in an effort to alleviate
issues seen in Windows machines not having the same MSVC runtime installed as
was used to build the wheels.
- ARMv8 wheels are now available, thanks to `odidev` for the pull request.
Changes from 2.7.1 to 2.7.2
---------------------------
- Support for Python 2.7 and 3.5 is deprecated and will be discontinued when
`cibuildwheels` and/or GitHub Actions no longer support these versions.
- Wheels are now provided for Python 3.7, 3.5, 3.6, 3.7, 3.8, and 3.9 via
GitHub Actions.
- The block size is now exported into the namespace as `numexpr.__BLOCK_SIZE1__`
as a read-only value.
- If using MKL, the number of threads for VML is no longer forced to 1 on loading
the module. Testing has shown that VML never runs in multi-threaded mode for
the default BLOCKSIZE1 of 1024 elements, and forcing to 1 can have deleterious
effects on NumPy functions when built with MKL.
- Use of `ndarray.tostring()` in tests has been switch to `ndarray.tobytes()`
for future-proofing deprecation of `.tostring()`, if the version of NumPy is
greater than 1.9.
- Added a utility method `get_num_threads` that returns the (maximum) number of
threads currently in use by the virtual machine. The functionality of
`set_num_threads` whereby it returns the previous value has been deprecated
and will be removed in 2.8.X.
Wrappers 1.3.1 | Solver 1.3.1 | 11/01/2020
allow to avoid linking against VC2014_1 on windows
do not mark move constructor / assignment operator of expression as noexcept. This is to circumvent a suspected bug in the GCC compiler in the manylinux1 image.
Wrappers 1.3.0 | Solver 1.3.0 | 10/21/2020
add c++ benchmarks and run them on CIs
modernize the c++ code by using more c++11 features
introduce move semantic in some c++ constructors to improve performances
add support for Python 3.9
Wrappers 1.2.0 | Solver 1.2.0 | 03/26/2020
make the the c++ part of the code c++11 compliant
use cppy for Python/C bindings
Better have this listed as breakage for py36-numpy than not having the
bulk builds start up because the packages using this still want to
build it for python 3.6

Now it should be more obvious when a package needs it as a dependency,
as it will fail loudly if it isn't declared as a tool.
While here, some duplicate dependencies on itstool were removed from the
MATE packages
This also requires gcc 4.8 at minimum, 4.9 for the full set of SIMD.
The configure script is patched to avoid the build adding -march=core-avx2,
which could conflict with user's CFLAGS.
This yields one common package to provide libfftw3 (double) and libfftw3f
(single) by default and optionally the Fortran bindings as well as
OpenMP and MPI variants, and those with long double or quad precision.
This changes all packages depending on fftwf in the same commit to minimize
the time of inconsistency. Soon, math/fftwf will disappear.
Upstream changes:
DBI 1.1.1 (2021-01-04)
Documentation
Expand "Get started" vignette to two tutorials, basic and advanced (#332, @jawond).
Bug fixes
dbAppendTable() now allows columns named sep (#336).
dbAppendTable() shows a better error message if the input has zero columns (#313).
sqlInterpolate() now correctly interprets consecutive comments (#329, @rnorberg).
dbQuoteLiteral() works for difftime objects (#325).
dbQuoteLiteral() quotes dates as YYYY-MM-DD without time zone (#331).
Internal
Switch to GitHub Actions (#326).
Update URL in DESCRIPTION.
to be built with c++11, though the library itself is c++03 clean.
necessary for GCC 10 hosts. also tested on GCC 7 / netbsd 9.x.
from Chavdar Ivanov on current-users.
most of these simply extend matching from "aarch64" to "aarch64eb"
in various forms of code. most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.
no pkg-bump because this shouldn't change packages on systems that
could already build all of these.
Changes in 0.15.0.1
* Bug in generation of Int/Word in both uniform and uniformR is
fixed. (#75)
Changes in 0.15.0.0
* withSystemRandomST and createSystemSeed are added.
* withSystemRandom is deprecated.
* random>=1.2 is dependency of mwc-random.
* Instances for type classes StatefulGen & FrozenGen defined in
random-1.2 are added for Gen.
* Functions in System.Random.MWC.Distributions and
System.Random.MWC.CondensedTable now work with arbitrary StatefulGen
* System.Random.MWC.uniformVector now works with arbitrary StatefulGen
as well and uses in-place initialization instead of generateM. It
should be faster for anything but IO and ST (those shoud remain
same).
Changes in 0.3.4.2
* Fixed crash in invIncompleteBeta (#68) for some inputs initial
approximation was computed incorrectly.
Changes in 0.3.4.1
* Precision of incompleteGamma improved.
Changes in 0.3.4.0
* Dependency on vector-th-unbox is dropped. All instances are written
by hand now.

this, the doctests test suite has been removed in favor of using
cabal-docspec to run the doctests.
* Explicitly mark modules as Safe.
5.5.10 [2021.01.21]

needlessly reject data types whose two last type parameters appear
as oversaturated arguments to a type family.
5.5.7 [2020.01.29]
* Add Data.Bifunctor.Biap.
5.0.8 [2020.12.30]
* Explicitly mark modules as Safe or Trustworthy.
* The build-type has been changed from Custom to Simple. To achieve
this, the doctests test suite has been removed in favor of using
cabal-docspec to run the doctests.
5.0.7 [2020.12.15]
* Move FunctorWithIndex (TracedT m w) instance from lens. This
instance depends on the indexed-traversable package. This can be
disabled using the flag of the same name.
0.6.2.1 [2020.12.30]
* The build-type has been changed from Custom to Simple. To achieve
this, the doctests test suite has been removed in favor of using
cabal-docspec to run the doctests.

In PKGSRC_FORTRAM=gfortran case, libcblas has no RPATH=/usr/pkg/gccXX/lib
and libgfortran and libquadmath are not found.
In PKGSRC_FORTRAN=g95 case, libcblas has no
RPATH=/usr/pkg/lib/gcc-lib/x86_64--netbsd/4.1.2 and libf95 is not found.
Use Fortran compiler as linker instread of C compiler to fix link.
The patch to system_info.py got upstreamed in a modified form which is
now backported here. On updating to 1.21, it shall be dropped.
In the process of upstreaming the patch, I learned that numpy really
needs to use cblas for proper acceleration, so it does that now and
gets a PKGREVISION bump because of that.
Version 2.43
Installing the Python interface through PyPI is supported.
Version 2.42
For dual CD solvers (logistic/l2 losses but not l1 loss), if a maximal number of iterations is reached, LIBLINEAR directly switches to run a primal Newton solver.
KISS FFT - A mixed-radix Fast Fourier Transform
There are many great fft libraries already around. Kiss FFT is not trying
to be better than any of them. It only attempts to be a reasonably efficient,
moderately useful FFT that can use fixed or floating data types and can be
incorporated into someone's C program in a few minutes with trivial licensing.
This introduces a 'generic' variant for blas_opt_info() and
lapack_opt_info() that looks into BLAS_LIBS and LAPACK_LIBS. The
others stay alive, and you can choose via NPY_BLAS_ORDER and
NPY_LAPACK_ORDER.
Will post this upstream … hoping for the best.
Other projects seem just to abuse the [openblas] entry in
site.cfg, or whatever hacks to trick this into building with
a generic BLAS. One hurdle is that using openblas seems to
assume that CBLAS is present in there, which it is not in pkgsrc.
We could think about introducing some alternatives stuff that uses
stubs for all the related libs anyway, but that is not my application,
which builds things from source. For binary packages, it would be
interesting, though. See Debian and Genoot for prior art on that.
Many many changes including
Oneway ANOVA-type analysis
~~~~~~~~~~~~~~~~~~~~~~~~~~
Several statistical methods for ANOVA-type analysis of k independent samples
have been added in module :mod:`~statsmodels.stats.oneway`. This includes
standard Anova, Anova for unequal variances (Welch, Brown-Forsythe for mean),
Anova based on trimmed samples (Yuen anova) and equivalence testing using
the method of Wellek.
Anova for equality of variances or dispersion are available for several
transformations. This includes Levene test and Browne-Forsythe test for equal
variances as special cases. It uses the `anova_oneway` function, so unequal
variance and trimming options are also available for tests on variances.
Several functions for effect size measures have been added, that can be used
for reporting or for power and sample size computation.
Multivariate statistics
~~~~~~~~~~~~~~~~~~~~~~~
The new module :mod:`~statsmodels.stats.multivariate` includes one and
two sample tests for multivariate means, Hotelling's t-tests',
:func:`~statsmodels.stats.multivariate.test_mvmean`,
:func:`~statsmodels.stats.multivariate.test_mvmean_2indep` and confidence
intervals for one-sample multivariate mean
:func:`~statsmodels.stats.multivariate.confint_mvmean`
Additionally, hypothesis tests for covariance patterns, and for oneway equality
of covariances are now available in several ``test_cov`` functions.
New exponential smoothing model: ETS (Error, Trend, Seasonal)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Class implementing ETS models :class:`~statsmodels.tsa.exponential_smoothing.ets.ETSModel`.
- Includes linear and non-linear exponential smoothing models
- Supports parameter fitting, in-sample prediction and out-of-sample
forecasting, prediction intervals, simulation, and more.
- Based on the innovations state space approach.
Forecasting Methods
~~~~~~~~~~~~~~~~~~~
Two popular methods for forecasting time series, forecasting after
STL decomposition (:class:`~statsmodels.tsa.forecasting.stl.STLForecast`)
and the Theta model
(:class:`~statsmodels.tsa.forecasting.theta.ThetaModel`) have been added.
See 0.12.0-0.12.2 at https://www.statsmodels.org/stable/release/
for the full story, including deprecations.
2.7.3 (2021-02-25)
------------------
- Add pytest plugin options to skip and xfail individual tests
and xfail the unsupported ndarray-1.0.0 example.
- Fix bug resulting in invalid strides values for views over
FITS arrays.
2.7.2 (2021-01-15)
------------------
- Fix bug causing test collection failures in some environments.

Highlights of this release
scipy.ndimage improvements: Fixes and ehancements to boundary extension
modes for interpolation functions. Support for complex-valued inputs in many
filtering and interpolation functions. New grid_mode option for
scipy.ndimage.zoom to enable results consistent with scikit-image's
rescale.
scipy.optimize.linprog has fast, new methods for large, sparse problems
from the HiGHS library.
scipy.stats improvements including new distributions, a new test, and
enhancements to existing distributions and tests
Deprecated features
scipy.spatial changes
Calling KDTree.query with k=None to find all neighbours is deprecated.
Use KDTree.query_ball_point instead.
distance.wminkowski was deprecated; use distance.minkowski and supply
weights with the w keyword instead.
Backwards incompatible changes
Using scipy.fft as a function aliasing numpy.fft.fft was removed after
being deprecated in SciPy 1.4.0. As a result, the scipy.fft submodule
must be explicitly imported now, in line with other SciPy subpackages.
scipy.signal changes
The output of decimate, lfilter_zi, lfiltic, sos2tf, and
sosfilt_zi have been changed to match numpy.result_type of their inputs.
The window function slepian was removed.
The frechet_l and frechet_r distributions were removed.

- fixed cell_negative color #271
- fixed locked cells when saving #261
- fixed DEL key in insert mode #272
- fix when resizing column #266
- "Autobackup - case insensitive QER options when backup exists"
- fixed segfault when fcopy'ing with no selection while on first column
- Call write triggers on value clear
- Use sc_info to report trigger exit code
- fixed#277
- Grow table up to MAXROWS exactly
- Remove redundant if clause (God only knows where that was).
- fix in getVertex that prevented rebuild_graph to work properly.
- fix annoying bug because of not resetting inputline_pos to 0 when
confirming a command in COMMAND_MODE
- fix in let and slet. existing vertexs should not be removed.
- added "eval_visited" in vertex struct for not to collide with
current "visited", since:
EvalAll uses EvalBottomUp
EvalBottomUp uses EvalJustOneVertex
EvalJustOneVertex uses eval
eval uses GraphAddEdge
GraphAddEdge uses GraphIsReachable
GraphIsReachable uses visited
and EvalBottomUp also uses uses visited!
- Also changed markAllVerticesNotVisited and
All_vertexs_of_edges_visited functions.
- Some other issues fixed: #228, #234, #239, #240, #244, #246, #260,
#295, #308
- .. and many other fixes and improvements!
Pending:
The most significative issue is regarding circular references.
This have to be deeply analyzed and with the collaboration of the
community
it would be hopefully fixed by v0.9.
The downstream configure code freaked out when info['define_macros'] was not set.
It is now defined and empty.
I hope it's fine to just push this without further notice.
Build was confirmed by oster on NetBSD-9.1/amd64 and tested by me
on Linux/amd64.
Fix openblas build issues, mainly by updating to 0.3.10.

openblas: flags from environment again to un-break PICy build
The bug that prompted us to force the compiler flags in the
make arguments is fixed. Now we got a different one: The logic
that decides to add -fPIC where needed is overridden when doing
this, resulting in relocation errors (strangely, not with every
toolchain).
So let's remove that again and take FFLAGS and friends from the
environment again.

openblas: version 0.3.10
This updated fixes the build with gcc 10 (segfault in cblat1 test).
I did not go all the way to the current 0.3.12, as that would
need some hacking of chosen compiler flags. 0.3.13 should be
the next one.
This commit also fixes the ARCH → ARCH_ sed to change all
occurences on a line.
This fulfills pkg/55999 and was approved by wiz during freeze.
The previous state included our BLAS choice but the build
did not honour the selected libs. This patches the config
script to not search for LAPACK and BLAS, using our settings
instead. Hopefull we can get that option upstreamed.

Benchmarking:
- Speed tests now call cpucycles() before setting resource limits. This
is important on platforms where cpucycles() needs to read files.
Verification:
- Support for SignExt and several more peephole optimizations, working
towards support for simpler symbolic-execution backend. Various
updates to work with angr8 and python3.
## 3.3.0
This is a production release that changes one behavior and fixes documentation
bugs.
The changed behavior is the treatment of `-e` and `-f` when given through
`BC_ENV_ARGS` or `DC_ENV_ARGS`. Now `bc` and `dc` do not exit when those options
(or their equivalents) are given through those environment variables. However,
`bc` and `dc` still exit when they or their equivalents are given on the
command-line.
Note that "DC_ENV_ARGS" will lead to dc exiting; this was new in 3.1.4
and I have reported that upstream.
Upstream changes, less bugfixes (and hence first/second do not make
sense; see the full NEWS.md in the sources if that upsets you):
## 3.2.5
This is a production release that fixes several bugs and adds a couple small
things.
The two most important bugs were bugs that causes `dc` to access memory
out-of-bounds (crash in debug builds). This was found by upgrading to `afl++`
from `afl`. Both were caused by a failure to distinguish between the same two
cases.
Fourth, the pseudo-random number now attempts to seed itself with `/dev/random`
if `/dev/urandom` fails.
## 3.2.0
This is a production release that has one bug fix and a major addition.
The major addition is a way to build a version of `bc`'s math code as a library.
This is done with the `-a` option to `configure.sh`. The API for the library can
be read in `./manuals/bcl.3.md` or `man bcl` once the library is installed with
`make install`.
This library was requested by developers before I even finished version 1.0, but
I could not figure out how to do it until now.
If the library has API breaking changes, the major version of `bc` will be
incremented.
## 3.1.4
This is a production release that fixes one bug, changes two behaviors, and
removes one environment variable.
The behavior that was changed is that `bc` now exits when given `-e`, `-f`,
`--expression` or `--file`. However, if the last one of those is `-f-` (using
`stdin` as the file), `bc` does not exit. If `-f-` exists and is not the last of
the `-e` and `-f` options (and equivalents), `bc` gives a fatal error and exits.
Next, I removed the `BC_EXPR_EXIT` and `DC_EXPR_EXIT` environment variables
since their use is not needed with the behavior change.
Finally, I made it so `bc` does not print the header, though the `-q` and
`--quiet` options were kept for compatibility with GNU `bc`.

The package patches a few commands of the LaTeX2e kernel and
the amsmath and mathtools packages to be more compatible with
the LuaTeX engine. It is only meaningful for LuaLaTeX documents
containing mathematical formulas, and does not exhibit any new
functionality. The fixes are mostly moved from the unicode-math
package to this package since they are not directly related to
Unicode mathematics typesetting.

Changelog:
0.16.1
fixed a build issue on 32-bit linux platforms, caused by slicing
of integer string ID values.
worked around floating point rounding errors which prevented
two theoretically-equal numeric values from being evaluated as
equal in test code.
0.16.0
documentation
added quickstart sections for using model_context and
document classes.
added code example for cell_access class.
C++ API
added new function to allow printing of single formula
tokens.
added method for setting cached results on formula cells
in model_context.
changed the model_context design to ensure that all sheets
are of the same size.
added an accessor method to formula_model_access interface
(and implicitly in model_context) that directly returns a
string value from cell.
added cell_access class for querying of cell states without
knowing its type ahead of time.
added document class which provides a layer on top of
model_context, to abstract away the handling of formula
calculations.
deprecated model_context::erase_cell() in favor of
empty_cell().
formula parser / interpreter
added support for 3D references - references that contain
multiple sheets.
added support for the exponent (^) and concatenation (&)
operators.
fixed incorrect handling of range references containing
whole columns such as A:A.
added support for unordered range references - range
references whose start row or column is greater than their
end position counterparts, such as A3:A1.
fixed a bug that prevented nested formula functions from
working properly.
implemented Calc A1 style reference resolver.
misc
formula results now directly store the string values when
the results are of string type. They previously stored
string ID values after interning the original strings.
removed build-time dependency on spdlog.
pkgsrc changes: Remove non-installed examples with non-POSIX sh
constructs.
What would be in upstream NEWS:
Qhull 2020.2 enhances the C++ interface with QhullUser and support for Voronoi diagrams.
Qhull 2020.1 makes minor API changes
1.19.5:
BUG: Fix segfault due to out of bound pointer in floatstatus...
BUG: fix np.timedelta64('nat').__format__ throwing an exception
BUG: Fixed file handle leak in array_tofile.
BUG: Raise recursion error during dimension discovery
BUG: Fix subarray dtype used with too large count in fromfile
BUG: 'bool' object has no attribute 'ndim'
BUG: ensure _UFuncNoLoopError can be pickled
BLD: use BUFFERSIZE=20 in OpenBLAS
BLD: update to OpenBLAS 0.3.13
BUG: make a variable volatile to work around clang compiler bug
REL: Prepare for the NumPy 1.19.5 release.
FFTW 3.3.9:
* New API fftw_planner_nthreads() returns the number of threads
currently being used by the planner.
* Fix incorrect math in 128-bit generic SIMD
* Fix wisdom for avx512.
The avx512 alignment requirement was set to 64 bytes, but this is
wrong. Alignment requirements are a property of the platform (e.g.,
x86) and not of the instruction set (e.g., AVX). Among other
things, this broke wisdom with avx512.
Note that avx512 support is still experimental because the FFTW
authors have no avx512 hardware available for testing.
* fftw_threads_set_callback function to change the threading backend at runtime.
