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.

* 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.

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

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.
- Fix bug when decompressing arrays with numpy 1.20
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.
Packaging changes:
- Some patches got upstreamed
- Upstream now defaults to name=sc-im so it no longer needs to be set
Changes, (reformatted) from the official changelog:
New features:

:cellcolor.
- OpenBSD support (mostly wordexp() workaround)
- Correct lua api function names in doc
- always generate backup file when opening file
- renamed scim to sc-im in Makefile
- Document trigger return value convention
Issues fixed:
- fix bug when deleting an ent that for instance has a @sum()... it
used to remove its vertex and THE ENTS LINKED to THEM!
- fix error messages when using "scim --version" and color definitions
are intented to be applied from .scimrc.
- fix in waiting for valid command to complete after pressing ESC key.
- fix in parse_str so a word with white space can be stored in
dictionary value
- fix when setting default_paste_from_clipboard_cmd

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.

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.
Approved during freeze by wiz.
