* Avoid `'Dimension too large' error` for some (unpredictable)
combinations of font choice and the `Scale` option. Problems are still
known to occur for very large or very small values of `Scale`.
* Documentation is now run through ‘continuous integration’ (viz,
*Travis* for the time being) as well as the test suite.
* Add note to readme that the `lm-math` package is required for minimal
functionality.
* Spacing fixed for maths fonts loaded with the `Scale` fontspec feature
* Commands like `\crampedtextstyle` now longer lead to an infinite loop
under XeTeX.
* Improvements to the functionality of the test suite. (Although more
tests would be nice.)
* Test suite is now (successfully) run with `expl3` debug mode enabled.
If not using builtin curses and the ncurses bl3 is included before
ncursesw, as happens through the lua option, the ncurses bl3 sabotages
-lncursesw so make sure to include ncursesw first thing.

Version 0.43.1
This is a bugfix release that provides minor changes to fix: a bug in branch
pruning, bugs in `np.interp` functionality, and also fully accommodate the
NumPy 1.16 release series.
* NumPy 1.16 support
* Refactor np.interp
* Rewrite pruned conditionals as their evaluated constants.
PLIST was wrong due to build system using python's sys.platorm, which the
package Makefile incorrectly tried to replicate using pkgsrc variables.
Also added LICENSE and fixed one undocumented patch.

Changes from 3.5.0 to 3.5.1
- Maintenance release to fix how PyPi repo is handling wheel versions.
Changes from 3.4.4 to 3.5.0
Improvements
- When copying data from native HDF5 files with padding in compound types,
the padding is not removed now by default. This allows for better
compatibility with existing HDF5 applications that expect the padding
to stay there.
Also, when the description is a NumPy struct array with padding, this
is honored now. The previous behaviour (i.e. getting rid of paddings) can
be replicated by passing the new allow_padding parameter when opening
a file. For some examples, see the new examples/tables-with-padding.py
and examples/attrs-with-padding.py.
- Added a new flag --dont-allow-padding in ptrepack utility so as to
replicate the previous behaviour of removing padding during file copies.
The default is to honor the original padding in copies.
- Improve compatibility with numpy 1.16.
- Improve detection of the LZO2 library at build time.
- Suppress several warnings.
- Add AVX2 support for Windows.
Version 0.43.0
In this release, the major new features are:
* Initial support for statically typed dictionaries
* Improvements to hash() to match Python 3 behavior
* Support for the heapq module
* Ability to pass C structs to Numba
* More NumPy functions: asarray, trapz, roll, ptp, extract

CHANGES IN R 3.5.3:
INSTALLATION on a UNIX-ALIKE:
* Detection of flags for C++98/11/14/17 has been improved: in
particular if CXX??STD is set, it is tried first with no
additional flags.
PACKAGE INSTALLATION:
* New macro F_VISIBILITY as an alternative to F77_VISIBILITY. This
will become the preferred form in R 3.6.0.
BUG FIXES:
* writeLines(readLines(fnam), fnam) now works as expected, thanks
to Peter Meissner's PR#17528.
* setClassUnion() no longer warns, but uses message() for now, when
encountering "non local" subclasses of class members.
* stopifnot(exprs = T) no longer fails.

Changelog:
# General improvements
The Octave plotting system now supports high resolution screens, i.e., those with greater than 96 DPI which are referred to as HiDPI/Retina monitors.
Unicode character support for files and folders in Windows.
A new core function movfun will apply a function to a sliding window of arbitrary size on a dataset and accumulate the results. Many common cases have been implemented using the naming scheme movXXX where XXX is the function that will be applied. For example, the moving average over a dataset is movmean. New moving window functions:
movfun movslice movmad movmax movmean movmedian movmin movprod movstd movsum movvar
The fsolve function has been tweaked to use larger step sizes when calculating the Jacobian of a function with finite differences. This leads to faster convergence.
The ranks function has been recoded for performance and is now 25X faster. In addition, it now supports a third argument that specifies how to resolve the ranking of tie values.
The function randi has been recoded to produce an unbiased (all results are equally likely) sample of integers. This may produce different results in existing code. If it is necessary to reproduce the exact random integer sequence as in previous versions use
ri = imin + floor ((imax - imin + 1) * rand ());
The function isdefinite now returns true or false rather than -1, 0, or 1. To test for a positive semi-definite matrix (old output of 0) check whether the following two conditions hold:
isdefinite (A) => 0 and isdefinite (A + 5*TOL, TOL) => 1
The intmax, intmin, and flintmax functions now accept a variable as input. Existing code to query the range of an existing variable can be simplified by removing the call to class that was previously required. For example defining the variable x = int8 (3) in the workspace, calls like
range = [ intmin(class(x)), intmax(class(x)) ]
can in Octave 5 be simplified to range = [ intmin(x), intmax(x) ].
The path handling functions no longer perform variable or brace expansion on path elements and Octave’s load-path is no longer subject to these expansions.
A new printing device is available, "-ddumb", which produces ASCII art for plots. This device is only available with the gnuplot toolkit.
# Dependencies
The GUI requires Qt libraries. The minimum Qt4 version supported is Qt4.8. Qt5 of any version is preferred.
The OSMesa library is no longer used. To print invisible figures when using OpenGL graphics, the Qt QOFFSCREENSURFACE feature must be available and you must use the qt graphics toolkit.
The FFTW library is now required to perform FFT calculations. The FFTPACK sources have been removed from Octave.
Matlab compatibility
* Many improvements.
1.16.2:
TST: fix vmImage dispatch in Azure

ixion 0.14.1
* addressed a number of coverity issues.
* Fixed build issues on 32-bit platforms.
* fixed warnings on shadowed variables during build with -Wshadow
compiler option.
ixion 0.14.0
* implemented MMULT built-in formula function which makes use of the
grouped formula support.
* added support for grouped formulas.
* added experimental compute engine framework to potentially accelerate
certain computations in the future. It's not used yet.
* refactored formula cell storage to use ref-countered formula cell
objects.
Changes from version 4.0.1 to version 4.0.2:
- Corrected minimal GMP version in the INSTALL file and the MPFR manual.
- Option -pedantic is now always removed from __GMP_CFLAGS (see INSTALL).
- Shared caches: cleanup; really detect lock failures (abort in this case).
- Improved MPFR manual. In particular, corrected/completed the
mpfr_get_str description in order to follow the historical behavior
and GMP's mpf_get_str function.
- Bug fixes (see ChangeLog file).

NEWS for version 1.2 (released on February 11, 2016)
--------------------------------------------------------------------------
New and Changed Features
========================
o Improved the efficiency of the conversion procedure for polyhedra
by adding a quick adjacency check.
o In the Java language interface, throw an exception when trying
to build a disequality Constraint.
Bugfixes
========
o Fixed a bug in the implementation of methods
Pointset_Powerset<PSET>::relation_with(const Constraint&) const;
and
Pointset_Powerset<PSET>::relation_with(const Congruence&) const;
whereby the computed result for relations strictly_intersects()
and saturates() could have been wrong.
o Fixed a bug in the implementation of dense rows.
o Portability improved.

Jan. 14, 2019 Peter Wang documentation
improved documentation based on the original README.txt, with examples to
show the syntax.
Jan. 14, 2019 Enrico Gregorio `fp-exp.sty' and `lfp.sty`
Fixed two unprotected end-of-lines in the above files that can, under
certain circumstances, add spaces in the output, causing unwanted drifting.
* Restore behaviour of legacy syntax `x_\mathrm{x}` (i.e., with no braces).
While strictly ‘incorrect’, this usage is widely used.
N.B. this syntax is not supported for the `\symXX` commands.
* Add `\cuberoot` and `\fourthroot` as proper radicals.
* Some additional input subscripts/superscripts.
* Some documentation additions (thanks for the contributions).
* Deprecation warning: the *internal* `\__um_switchto_XX:` commands
will be dropped in a future release in favour of `\__um_switch_to:n {XX}`
(or similar). These are internal commands and shouldn't be used by
third-parties; please write if you have a use case.
