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.

pkgsrc: since the volk release tarball only provides the required cpu_features
library as a git submodule that has to be manually cloned, we instead depend on
devel/cpu_features from pkgsrc and patch the cmake files to accept the static
library as an external dependency.

Update README to be more verbose and to improve usefulness.
Compilers
AppleClang: Treat AppleClang as Clang.
Paired with the cpu_features introduction, this enables us to use architecture
specific kernels on a broader set of platforms.
CMake
Enable to not install volk_modtool.
Remove "find_package_handle_standard_args" warning.
cpu_features
Use cpu_features v0.6.0 as a private submodule to detect available CPU
features.
Fix incorrect feature detection for newer AVX versions.
Circumvent platform specific feature detection.
Enable more architecture specific kernels on more platforms.
Kernels
Disable slow and broken SSE4.1 kernel in volk_32fc_x2_dot_prod_32fc
Adjust min/max for 32f_s32f_convert_8i kernel

Changelog:
SymPy 1.7 was released on 29th November 2020.
This version of SymPy has been tested on Python 3.6, 3.7, 3.8, 3.9 and PyPy.
See our Python version support policy for more information on when we plan to
drop support for older Python versions.
Note in particular that SymPy 1.5.1 was the last release to support Python 2.7.
SymPy 1.7 will not work on Python 2.7. Python 2.7 users should install SymPy
1.5.1 and will not be able to install any further SymPy updates without
updating to Python 3.
Install SymPy with
pip install -U sympy
or if you use Anaconda
conda install sympy
Highlights
There are many changes in 1.7 (see below).
Backwards compatibility breaks and deprecations
* core
+ Modules and names that were accidentally importable from sympy are no
longer importable. In sympy 1.6 importing and using these names would
give a deprecation warning. In sympy 1.7 these names are removed. As an
example from sympy import add would need to be from sympy.core import
add or import sympy.core.add as add. (#19554 by @oscarbenjamin)
+ DEPRECATION: Using non-Expr args in Add, Mul or Pow is now deprecated (
#19445 by @oscarbenjamin)
* diffgeom
+ Manifold.patches attribute is deprecated. (#19368 by @JSS95 and
@mcpl-sympy)
+ Patch.coord_systems attribute is deprecated. (#19368 by @JSS95 and
@mcpl-sympy)
+ Class signature names of CoordSystem is deprecated. CoordinateSymbol
class and CoordSystem.symbols attribute are introduced instead. (#19368
by @JSS95 and @mcpl-sympy)
+ CoordSystem.transforms, CoordSystem.connect_to, and
CoordSystem.coord_tuple_transform_to are deprecated. Class signature
relations, CoordSystem.transformation and CoordSystem.transform are
introduced instead. (#19368 by @JSS95 and @mcpl-sympy)
* printing
+ sympy.printing.pretty.pretty_symbology.xstr has been deprecated (#20081
by @eric-wieser)
+ The unicode argument to sympy.printing.stringpict.prettyForm has been
deprecated (#20081 by @eric-wieser)
+ The deprecation of calling preview with viewer="StringIO" is now
expired instead of forgotten (a regression in 1.6.0) (#19905 by
@eric-wieser)
+ The modules sympy.printing.ccode, sympy.printing.fcode, and
sympy.printing.cxxcode have been renamed to sympy.printing.c,
sympy.printing.fortran, and sympy.printing.cxx, respectively. This was
done to avoid conflicts that occur when a module name is the same as a
function name. The modules are still importable under their old names
but doing so is deprecated and a warning will be given (#19908 by
@asmeurer)
+ from sympy.printing.codeprinter import Assignment no longer works. You
should use from sympy.codegen import Assignment, which is where
Assignment has lived since SymPy 1.1. (#19908 by @asmeurer)
+ Calling preview with viewer="file" no longer looks for a file
executable (a regression in 1.6.0) (#19905 by @eric-wieser)
* solvers
+ solve_linear_system is now a thin wrapper for linsolve. It is
recommended to use linsolve in new code. solve_linear_system maybe
deprecated or removed in future. (#18814 by @oscarbenjamin)
* utilities
+ find_executable is deprecated in favor of the builtin shutil.which. (#
19634 by @eric-wieser)
Changes
* algebras
+ Added DocString for integrate function of quaternion class. (#19410 by
@mohitshah3111999)
* codegen
+ Added support for generating calls to scipy.special.cosm1. (#20011 by
@bjodah)
+ sympy.codegen and sympy.combinatorics are no longer imported as part of
from sympy import *. The codegen and combinatorics modules do not have
any names that are included in the top-level namespace, so their being
imported with the top-level SymPy was a mistake. This improves the
import time of from sympy import *. (#19908 by @asmeurer)
+ Added support for generating calls to numpy.logaddexp &
numpy.logaddexp2. (#19880 by @bjodah)
+ Fix bugs to the parser of matrix expressions in order to build
CodegenArray objects correctly. (#19197 by @Upabjojr)
* combinatorics
+ Fixed a bug in PermutationGroup.minimal_blocks caused by modifying a
list while iterating over its indices. (#19954 by @ilya-pchelintsev)
* concrete
+ Implemented Raabe's Test (#18656 by @sachin-4099)
* core
+ Fixed a few broken cases of expr.is_integer (#20450 by @coproc and
@tbennun)
+ Modules and names that were accidentally importable from sympy are no
longer importable. In sympy 1.6 importing and using these names would
give a deprecation warning. In sympy 1.7 these names are removed. As an
example from sympy import add would need to be from sympy.core import
add or import sympy.core.add as add. (#19554 by @oscarbenjamin)
+ Zero raised to power Negative Infinity gives ComplexInfinity(zoo)
instead of zero (#20212 by @sidhu1012)
+ Extensible add, mul and power functions are introduced to allow sympy
objects to define what classes should be used for them in place of Add,
Mul and Pow (e.g. matrices use MatAdd). This is an experimental
approach aimed at enabling the behaviour of core routines (expand,
collect, etc) to be customised by user-defined types (e.g. MatAdd
rather than Add). This mechanism is still experimental, is not fully
implemented across the core and might be changed or removed in a future
release of sympy. (#19463 by @JSS95 and @mcpl-sympy)
+ divmod on sympy.Float with 0 numerator now results in (0, 0). (#20109
by @eriknw)
+ Dict operations no longer automatically converts strings into SymPy
types. (#19911 by @asmeurer)
+ Dict operations no longer raise SympifyError. (#19911 by @asmeurer)
+ Fixes _eval_nseries() function of power.py (#19508 by @sachin-4099)
+ Remove optional dependency on fastcache (#19492 by @pbrady)
+ DEPRECATION: Using non-Expr args in Add, Mul or Pow is now deprecated (
#19445 by @oscarbenjamin)
+ When creating an Add or Mul with evaluate=False identities (0 or 1) are
no longer removed. (#19450 by @oscarbenjamin)
+ Fixes _eval_nseries() function of mul.py (#19369 by @sachin-4099)
+ Sum is now included in count_ops results (#19261 by @smichr)
+ match has been optimized to improve term-matching in Add (#19261 by
@smichr)
+ match will automatically ignore bound symbols when matching (#19261 by
@smichr)
+ match results will no longer contain extraneous symbols (only those
requested) (#19261 by @smichr)
+ as_dummy should give a canonical result for expressions having bound
symbols (#19261 by @smichr)
+ Lambdas written in terms of different symbols will no longer compare
equal; this was an abuse of the Python == operator (#19261 by @smichr)
+ expr: A new method is_meromorphic is added. (#19306 by @jksuom)
* diffgeom
+ Manifold.patches attribute is deprecated. (#19368 by @JSS95 and
@mcpl-sympy)
+ Patch.coord_systems attribute is deprecated. (#19368 by @JSS95 and
@mcpl-sympy)
+ Class signature names of CoordSystem is deprecated. CoordinateSymbol
class and CoordSystem.symbols attribute are introduced instead. (#19368
by @JSS95 and @mcpl-sympy)
+ CoordSystem.transforms, CoordSystem.connect_to, and
CoordSystem.coord_tuple_transform_to are deprecated. Class signature
relations, CoordSystem.transformation and CoordSystem.transform are
introduced instead. (#19368 by @JSS95 and @mcpl-sympy)
+ CoordSystem.jacobian_determinant method is introduced. (#19368 by
@JSS95 and @mcpl-sympy)
* functions
+ lambdify added a warning when args is a set. (#19792 by @foice,
@RobertoFranceschini, and @sylee957)
+ Fixes _eval_nseries method of log (#20002 by @sachin-4099)
+ Adds _eval_is_meromorphic method and _eval_aseries to class lowergamma
(#19990 by @sachin-4099)
+ Adds _eval_is_meromorphic method and _eval_rewrite_as_tractable method

@DaveWitteMorris and @gschintgen)
+ Corrects the _eval_as_leading_term() method of tan and sec functions (#
19461 by @sachin-4099)
+ bsplines are more robust in terms of handling symbolic knots (#19272 by
@smichr)
* geometry
+ Ellipses with eccentricity >=1 and for eccentricity < 0 will be handled
as trivial cases (#20045 by @agrawalshubham01)
* integrals
+ upgrades to manualintegrate to support inverse trig functions! (#19993
by @iammosespaulr)
* interactive
+ The _repr_latex_, _repr_svg_, and _repr_png_ methods of subclasses of

#19944 by @eric-wieser)
* logic
+ Binary boolean operators on Boolean objects no longer coerce strings (#
20093 by @eric-wieser)

determining if a matrix is positive semidefinite. (#19556 by @galbwe)
+ Explicit non-matrix are treated as scalar (#19533 by @mloubout)
+ QRdecomposition will return matrices with zero rows and columns for
zero rank matrices. e.g. Matrix([[0, 0, 0], [0, 0, 0], [0, 0, 0]]) will
be decomposed with Matrix(3, 0, []) and Matrix(0, 3, []) (#19319 by
@sylee957)
+ Added Matrix.companion for creating dense companion matrix. (#19339 by
@sylee957)

+ VectorLatexPrinter now know about the same trig functions as the
regular printer (#19684 by @eric-wieser)
+ When printing, Vector and Dyadic now respect keyword-arguments to sstr
and latex. As a result, these no longer use vector printing
customizations unless init_vprinting has been called. (#19640 by

Gaussian domains automatically when I is present in the input. Add
factorisation over the Gaussian integers (ZZ_I). The polys keyword

+ The modules sympy.printing.ccode, sympy.printing.fcode, and
sympy.printing.cxxcode have been renamed to sympy.printing.c,
sympy.printing.fortran, and sympy.printing.cxx, respectively. This was
done to avoid conflicts that occur when a module name is the same as a
function name. The modules are still importable under their old names

by @eric-wieser)
+ preview no longer fails with ValueError if the preamble contains a %
character. (#19858 by @eric-wieser)
+ Types which are not recognized by the LaTeX printer no longer have
their __str__ interpreted as LaTeX, and have their str(...) printed as
pre-formatted text as if they were printed normally. This includes the
builtin str type: latex("hello") now results in the latex \mathtt{\text
{hello}}.
If a custom type intends to be interpreted as latex, it should define
the _latex hook as described in the docs:
def _latex(self, printer):
return str(self) # indicate that the result of __str__ is LaTeX-compatible
To print a string containing LaTeX math using MathJax, use
import IPython
IPython.display.Math(string)

available. As a result, it now works with a MiKTeX installation on
windows. (#19635 by @eric-wieser)
+ LatexPrinter._print is no longer called on strings which have already
been converted to Latex. (#19614 by @eric-wieser)
+ A new sympy.printing.defaults.Printable base class was added, which is
a mixin providing _repr_latex_ in terms of LatexPrinter().doprint().
Any user type which subclasses this will opt into init_printing. (#

given as a ConditionSet but will no longer introduce new symbols (and
will leave the base set a a ConditionSet) when this cannot be done (#

+ Added the new n equations linear first-order non-constant coefficient
non-homogeneous solver where the coefficient matrix of the system of
ODEs is commutative with its antiderivative. (#19594 by @mijo2)
+ solveset will always use a symbol that has only either the real or
complex attribute and no other attribute; when a ConditionSet is
returned, the original symbol for which the solution is being sought
will be used if it does not cause evaluation of the result. (#19512 by

Needs patching and testing on platforms besides Linux
Version 2.41 released on July 29, 2020 (some bug fixes of version 2.40).
Version 2.40 released on July 22, 2020.
A new solver: dual coordinate descent method for linear one-class SVM; see the paper
The Newton solver is updated to have faster training speed; see the release note
A new option -R to allow users not to regularize bias (when -B 1 is used)
Upstream changes:
Formula 1.2-4
model.part() method tries to avoid calling has_dot() by checking the data attributes first. This can greatly improve speed when there are lots of variables in a model part that is actually not of interest.
Upstream changes:
Version 3.0-4
o Added "long"-format version of the O'Brien-Kaiser repeated-measures data set.
o Fix some typos in doc for CES11 data set (fixes courtesy of Andi Fugard).
Version 3.0-3
o Update references in docs and DESCRIPTION.
Convert to use the new mk/blas.buildlink3.mk rather than a specific blas
package
These dependents were overlooked in the initial upgrade and rev bump because
they listed blas in DEPENDS rather than including the bl3.
Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework. This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.
This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.
Details:
Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk

CHANGES IN R 4.0.3:
NEW FEATURES:
* On platforms using configure option --with-internal-tzcode,
additional values "internal" and (on macOS only) "macOS" are
accepted for the environment variable TZDIR. (See ?TZDIR.)
On macOS, "macOS" is used by default if the system timezone
database is a newer version than that in the R installation.
* When install.packages(type = "source") fails to find a package in
a repository it mentions package versions which are excluded by
their R version requirement and links to hints on why a package
might not be found.
* The default value for options("timeout") can be set from
enviromnent variable R_DEFAULT_INTERNET_TIMEOUT, still defaulting
to 60 (seconds) if that is not set or invalid.
This may be needed when child R processes are doing downloads,
for example during the installation of source packages which
download jars or other forms of data.
LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
* There is now support for parallelized Link-Time Optimization
(LTO) with GCC and for 'thin' LTO with clang _via_ setting the
LTO macro.
* There is support for setting a different LTO flag for the Fortran
compiler, including to empty when mixing clang and gfortran (as
on macOS). See file config.site.
* There is a new LTO_LD macro to set linker options for LTO
compilation, for example to select an alternative linker or to
parallelize thin LTO.
DEPRECATED AND DEFUNCT:
* The LINPACK argument to chol.default(), chol2inv(),
solve.default() and svd() has been defunct since R 3.1.0. Using
it now gives a warning which will become an error in R 4.1.0.
BUG FIXES:
* The code mitigating stack overflow with PCRE regexps on very long
strings is enabled for PCRE2 < 10.30 also when JIT is enabled,
since stack overflows have been seen in that case.
* Fix to correctly show the group labels in dotchart() (which where
lost in the ylab improvement for R 4.0.0).
* addmargins(*, ..) now also works when fn() is a local function,
thanks to bug report and patch PR#17124 from Alex Bertram.
* rank(x) and hence sort(x) now work when x is an object (as per
is.object(x)) of type "raw" _and_ provides a valid `[` method,
e.g., for gmp::as.bigz(.) numbers.
* chisq.test(*, simulate.p.value=TRUE) and r2dtable() now work
correctly for large table entries (in the millions). Reported by
Sebastian Meyer and investigated by more helpers in PR#16184.
* Low-level socket read/write operations have been fixed to
correctly signal communication errors. Previously, such errors
could lead to a segfault due to invalid memory access. Reported
and debugged by Dmitriy Selivanov in PR#17850.
* quantile(x, pr) works more consistently for pr values slightly
outside [0,1], thanks to Suharto Anggono's PR#17891.
Further, quantile(x, prN, names=FALSE) now works even when prN
contains NAs, thanks to Anggono's PR#17892. Ditto for ordered
factors or Date objects when type = 1 or 3, thanks to PR#17899.
* Libcurl-based internet access, including curlGetHeaders(), was
not respecting the "timeout" option. If this causes
unanticipated timeouts, consider increasing the default by
setting R_DEFAULT_INTERNET_TIMEOUT.
* as.Date(<char>) now also works with an initial "", thanks to
Michael Chirico's PR#17909.
* isS3stdGeneric(f) now detects an S3 generic also when it it is
trace()d, thanks to Gabe Becker's PR#17917.
* R_allocLD() has been fixed to return memory aligned for long
double type PR#16534.
* fisher.test() no longer segfaults when called again after its
internal stack has been exceeded PR#17904.
* Accessing a long vector represented by a compact integer sequence
no longer segfaults (reported and debugged by Hugh Parsonage).
* duplicated() now works also for strings with multiple encodings
inside a single vector PR#17809.
* phyper(11, 15, 0, 12, log.p=TRUE) no longer gives NaN; reported
as PR#17271 by Alexey Stukalov.
* Fix incorrect calculation in logLik.nls() PR#16100, patch from
Sebastian Meyer.
* A very old bug could cause a segfault in model.matrix() when
terms involved logical variables. Part of PR#17879.
* model.frame.default() allowed data = 1, leading to involuntary
variable capture (rest of PR#17879).
* tar() no longer skips non-directory files, thanks to a patch by
Sebastian Meyer, fixing the remaining part of PR#16716.
# ellipsis 0.3.1
* Fixed an incompatibility with R devel.
* New `?dots_used` topic from which you can inherit documentation for
`...` documentation when the dots are passed to methods.
Upstream changes:
Changes to Version 3.0-10
o Fixed as error when using parameter name "(Intercept)" with deltaMethod().
o Several changes to Boot() to correct bugs, support the plinear algorithm, to correct use of weights for lm, and allow use of weights for nls.
o Fix quantregLine() to work with development version 5.69 of quantreg package (following heads-up from Roger Koenker).
