The tensor product of two arrays is notionally an outer product of the
arrays collapsed in specific extents by summing along the appropriate
diagonals.
This is a lua port of the cassowary constraint solving toolkit. It allows
you to use lua to solve algebraic equations and inequalities and find the
values of unknown variables which satisfy those inequalities.

Done to fix build w/ gfortran 10. "make test" was mostly OK except for
three tests that returned nan where inf was expected ...
Highlights of this release:
wrappers for more than a dozen new LAPACK routines are now available
in scipy.linalg.lapack
Improved support for leveraging 64-bit integer size from linear algebra
backends
addition of the probability distribution for two-sided one-sample
Kolmogorov-Smirnov tests
New features:
Too many; see release notes at github.
Backwards incompatible changes:
The output signatures of ?syevr, ?heevr have been changed from
w, v, info to w, v, m, isuppz, info
The order of output arguments w, v of <sy/he>{gv, gvd, gvx} is
swapped.
The output length of scipy.signal.upfirdn has been corrected, resulting
outputs may now be shorter for some combinations of up/down ratios and
input signal and filter lengths.
scipy.signal.resample now supports a domain keyword argument for
specification of time or frequency domain input.
The Vector-Optimized Library of Kernel is a library that contains kernels of
hand-written SIMD code for different mathematical operations. Since each SIMD
architecture can be very different and no compiler has yet come along to
handle vectorization properly or highly efficiently, VOLK approaches the
problem differently.
VOLK is a sub-project of GNU Radio.
Many changes are identified for the update to 1.0.0; see News.md for
details.
Apparently, these include some breaking changes. See
`vignette("in-packages")` for a detailed transition guide.
Tested with lang/clisp and lang/ecl.

Version 18.10.2
CHANGES IN R 4.0.0:
SIGNIFICANT USER-VISIBLE CHANGES:
* Packages need to be (re-)installed under this version (4.0.0) of
R.
* matrix objects now also inherit from class "array", so e.g.,
class(diag(1)) is c("matrix", "array"). This invalidates code
incorrectly assuming that class(matrix_obj)) has length one.
S3 methods for class "array" are now dispatched for matrix
objects.
* There is a new syntax for specifying _raw_ character constants
similar to the one used in C++: r"(...)" with ... any character
sequence not containing the sequence )". This makes it easier to
write strings that contain backslashes or both single and double
quotes. For more details see ?Quotes.
* R now uses a stringsAsFactors = FALSE default, and hence by
default no longer converts strings to factors in calls to
data.frame() and read.table().
A large number of packages relied on the previous behaviour and
so have needed/will need updating.
* The plot() S3 generic function is now in package base rather than
package graphics, as it is reasonable to have methods that do not
use the graphics package. The generic is currently re-exported
from the graphics namespace to allow packages importing it from
there to continue working, but this may change in future.
Packages which define S4 generics for plot() should be
re-installed and package code using such generics from other
packages needs to ensure that they are imported rather than rely
on their being looked for on the search path (as in a namespace,
the base namespace has precedence over the search path).
See ${PREFIX}/lib/R/doc/NEWS for full changes.
At my request, upstream added a flag to install all locales, rather
than the locales that are installed on the current system. This leads
to a consistent PLIST (and more locales).
## 3.1.2
This is a production release that adds a way to install *all* locales. Users do
***NOT*** need to upgrade.
For package maintainers wishing to make use of the change, just pass `-l` to
`configure.sh`.
This package only exists to accomodate programs (e.g. gnuradio) which
have not yet updated to python3. Therefore, only allow numpy16 for
python2.7. (I believe there are zero py37-numpy16 users, and if so, that
should be discussed to understand why.)
Notable upstream changes:
## 3.1.0
The behavior that was adjusted was how code from the `-e` and `-f` arguments
(and equivalents) were executed. They used to be executed as one big chunk, but
in this release, they are now executed line-by-line.
The first bug fix in how output to `stdout` was handled in `SIGINT`. If a
`SIGINT` came in, the `stdout` buffer was not correctly flushed. In fact, a
clean-up function was not getting called. This release fixes that bug.
The second bug is in how `dc` handled input from `stdin`. This affected `bc` as
well since it was a mishandling of the `stdin` buffer.
The third fixed bug was that `bc` and `dc` could `abort()` (in debug mode) when
receiving a `SIGTERM`. This one was a race condition with pushing and popping
items onto and out of vectors.
The fourth bug fixed was that `bc` could leave extra items on the stack and
thus, not properly clean up some memory. (The memory would still get
`free()`'ed, but it would not be `free()`'ed when it could have been.)
The next two bugs were bugs in `bc`'s parser that caused crashes when executing
the resulting code.
The last two bugs were crashes in `dc` that resulted from mishandling of
strings.
## 3.0.2
This is a production release that adds `utf8` locale symlinks and removes an
unused `auto` variable from the `ceil()` function in the [extended math
library][16].
## 3.0.1
The second change is to make the new implementation of `ceil()` in `lib2.bc`
much more efficient.
Version 0.50.1:
This is a bugfix release for 0.50.0, it fixes a critical bug in error reporting
and a number of other smaller issues:
* Added except for possible Windows get_terminal_size exception
* Improve undefined variable error message
* Update the deprecation notices for 0.50.1
* Fixes literally not forcing re-dispatch for inline='always'
* Fix bad attr access on certain typing templates breaking exceptions.
* Fix cuda test
v0.9.0:
Highlights
loo-pit KDE and HDI were improved
html_repr of InferenceData objects for jupyter notebooks
Support for PyJAGS
from_pymc3 automatically retrieves coords and dims from model context
plot_trace now supports multiple aesthetics to identify chain and variable shape and supports matplotlib aliases
plot_hdi can now take already computed HDI values
Deprecations
from_pymc3 without a model context available raises aFutureWarning and will be deprecated in a future version
In plot_trace, chain_prop and compact_prop as tuples will now raise a FutureWarning
hdi with 2d data raises a FutureWarning
Instead:
1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed
Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.
Approved during the freeze by wiz@.
The package textproc/hs-cgrep does not install a Haskell library. This
was unexpected to mk/haskell.mk, which generated an obviously wrong PLIST
file for that package, and for 3 other packages.
Noticed by wiz.
Upstream changes:
multiple bug fixes and minor improvements
redesign of signal handling (not intended to be user visible)
Besides the following, see NEWS in the sources for details.
*First, the `2.7.0` release series saw a change in the option parsing. This made
me change one error message and add a few others. The error message that was
changed removed one format specifier. This means that `printf()` will seqfault
on old locale files. Unfortunately, `bc` cannot use any locale files except the
global ones that are already installed, so it will use the previous ones while
running tests during install. **If `bc` segfaults while running arg tests when
updating, it is because the global locale files have not been replaced. Make
sure to either prevent the test suite from running on update or remove the old
locale files before updating.** Once this is done, `bc` should install without
problems.*
*Second, **the option to build without signal support has been removed**. See
below for the reasons why.*
This is a production release with some small bug fixes, a few improvements,
three major bug fixes, and a complete redesign of `bc`'s error and signal
handling. **Users and package maintainers should update to this version as soon
as possible.**
Version 0.50.0:
This is a more usual release in comparison to the others that have been made in the last six months. It comprises the result of a number of maintenance tasks along with some new features and a lot of bug fixes.
Highlights of core feature changes include:
The compilation chain is now based on LLVM 9.
The error handling and reporting system has been improved to reduce the size of error messages, and also improve quality and specificity.
The CUDA target has more stream constructors available and a new function for compiling to PTX without linking and loading the code to a device. Further, the macro-based system for describing CUDA threads and blocks has been replaced with standard typing and lowering implementations, for improved debugging and extensibility.
3.1.4:
There is now a single code base for Python 2 and Python 3.
Python 2.7 is now the minimal Python version.
The installation can also now be done through a universal wheel, which helps with some external projects.
This Git version should have the same uncertainties code as PyPI version 3.1.4, but some accompanying files have been updated. This should have no impact on users. Developers are better off using this Git 3.1.4 version.
7 years of changes. For details see
https://www.shoup.net/ntl/doc/tour-changes.html
Remove libtool patch. This is too big to be maintained in
pkgsrc and should be upstreamed if deemed interesting enough.
Bump API requirements in bl3.mk because of this change, and
also because HElib (the only consumer of this library in pkgsrc)
needs the new version anyway and will be updated next.
Two of the files now use autoconf to insert the correct Perl interpreter.
The dependency "pre-install: replace-interpreter" was useless since then
replace-interpreter would be run once in a direct "bmake update" or
"bmake install", and twice in bulk builds since they first run "bmake
build" and then "bmake install". And even in the latter case, replacing
the interpreter twice had no effect since it was already replaced in the
configure phase.
The package provides basic arithmetic operations to 8 decimal
places for plain TeX or LaTeX. Results are exact when they fit
within the digit limits. Along with the basic package is an
optional extension that adds computation of sin, cos, log,
sqrt, exp, powers and angles. These are also exact when
theoretically possible and are otherwise accurate to at least 7
decimal places. In addition, the package provides a stack-based
programing environment.
It uses python 2.x and gnumeric upstream has turned off the plugin by
default as well.
Add a "python" option for those who really need it.
Update some outdated comments.
Bump PKGREVISION.
Gappa is a tool intended to help verifying and formally proving
properties on numerical programs dealing with floating-point or
fixed-point arithmetic.
Sollya is a tool environment and a library for safe floating-point
code development, particularly targeted at automated implementation
of math libraries like libm.
Derived from wip/sollya.

(translations and bugfixes omitted)
## 2.7.2
This is a production release with one major bug fix.
The `length()` built-in function can take either a number or an array. If it
takes an array, it returns the length of the array. Arrays can be passed by
reference. The bug is that the `length()` function would not properly
dereference arrays that were references. This is a bug that affects all users.
**ALL USERS SHOULD UPDATE `bc`**.
## 2.7.0
There is only one new feature: **`bc` now has a built-in pseudo-random number
generator** (PRNG).
The PRNG is seeded, making it useful for applications where
`/dev/urandom` does not work because output needs to be reproducible. However,
it also uses `/dev/urandom` to seed itself by default, so it will start with a
good seed by default.
On top of that, four functions were added to `bc`'s [extended math library][16]
to make using the PRNG easier:
* `frand(p)`: Generates a number between `[0,1)` to `p` decimal places.
* `ifrand(i, p)`: Generates an integer with bound `i` and adds it to `frand(p)`.
* `srand(x)`: Randomizes the sign of `x`. In other words, it flips the sign of
`x` with probability `0.5`.
* `brand()`: Returns a random boolean value (either `0` or `1`).
## 2.4.0
* The `bc` `&&` and `||` operators were made available to `dc` through the `M`
and `m` commands, respectively.
* `dc` macros were changed to be tail call-optimized.
The last item, tail call optimization, means that if the last thing in a macro
is a call to another macro, then the old macro is popped before executing the
new macro. This change was made to stop `dc` from consuming more and more memory
as macros are executed in a loop.
The `q` and `Q` commands still respect the "hidden" macros by way of recording
how many macros were removed by tail call optimization.

Version 1.0.1 Release Notes
============================
**Version 1.0.1 is the last release that supports Python 3.5**. All newer version will
require 3.6+ so that we can use formatting-strings and rely on dictionaries being ordered.
New features:
- added thermal distribution model and lineshape
- introduced a new argument ``max_nfev`` to uniformly specify the maximum number of function evalutions
**Please note: all other arguments (e.g., ``maxfev``, ``maxiter``, ...) will no longer be passed to the underlying
solver. A warning will be emitted stating that one should use ``max_nfev``.**
- the attribute ``call_kws`` was added to the ``MinimizerResult`` class and contains the keyword arguments that are
supplied to the solver in SciPy.
Bug fixes:
- fixes to the ``load`` and ``__setstate__`` methods of the Parameter class
- fixed failure of ModelResult.dump() due to missing attributes
- ``guess_from_peak`` function now also works correctly with decreasing x-values or when using
pandas
- the ``Parameter.set()`` method now correctly first updates the boundaries and then the value
Various:
- fixed typo for the use of expressions in the documentation
- removal of PY2-compatibility and unused code and improved test coverage
- removed deprecated ``isParameter`` function and automatic conversion of an ``uncertainties`` object
- inaccurate FWHM calculations were removed from built-in models, others labeled as estimates
- corrected spelling mistake for the Doniach lineshape and model
- removed unsupported/untested code for IPython notebooks in lmfit/ui/*
Version 0.49.1:
This is a bugfix release for 0.49.0, it fixes some residual issues with SSA form, a critical bug in the branch pruning logic and a number of other smaller issues:
* Fixed Threading Implementation Typos
* Fixes Remove references to cffi_support from docs and examples
* Fix invalid type in resolve for comparison expr in parfors.
* Fix erroneous rewrite of predicate to bit const on prune.
* Fixes SSA local def scan based on invalid equality assumption.
* Fixes naming error in array_exprs
* Fix. Incorrect race variable detection due to SSA naming.
* Make literal_unroll function work as a freevar.
* Unset the memory manager after EMM Plugin tests
* Fix some SSA issues
* Pin to sphinx=2.4.4 to avoid problem with C declaration
* Fix unifying undefined first class function types issue
* Update example in 5m guide WRT SSA type stability.
* Restore numba.types as public API
These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build. They will help to track changes
to the packages. The Haskell packages didn't have PLIST files because
their paths contained package hashes. These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.

Version 1.0.0 Release Notes
New features:
- no new features are introduced in 1.0.0.
Improvements:
- support for Python 2 and use of the ``six`` package are removed.
Various:
- documentation updates to clarify the use of ``emcee``.
Changes from 2.7.0 to 2.7.1
- Python 3.8 support has been added.
- Python 3.4 support is discontinued.
- The tests are now compatible with NumPy 1.18.
- `site.cfg.example` was updated to use the `libraries` tag instead of `mkl_libs`,
which is recommended for newer version of NumPy.
SciPy 1.4.1 is a bug-fix release with no new features
compared to 1.4.0. Importantly, it aims to fix a problem
where an older version of pybind11 may cause a segmentation
fault when imported alongside incompatible libraries.
SciPy 1.4.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with ``python -Wd`` and check for ``DeprecationWarning`` s).
Our development attention will now shift to bug-fix releases on the
1.4.x branch, and on adding new features on the master branch.

Bottleneck 1.3.2
Bug Fixes
- Explicitly declare numpy version dependency in ``pyproject.toml`` for Python 3.8, fixing
certain cases where ``pip install`` would fail.
and ``@0xb0b`` for reporting.
Bottleneck 1.3.1
Bug Fixes
- Fix memory leak in :func:`bottleneck.nanmedian` with the default argument of ``axis=None``.
- Add regression test for memory leak case
Bottleneck 1.3.0
Project Updates
- Bottleneck has a new maintainer, Christopher Whelan (``@qwhelan`` on GitHub).
- Documentation now hosted at https://bottleneck.readthedocs.io
- 1.3.x will be the last release to support Python 2.7
- Bottleneck now supports and is tested against Python 3.7 and 3.8.
- The ``LICENSE`` file has been restructured to only include the license for the Bottleneck project to aid license audit tools. There has been no change to the licensing of Bottleneck.
- Licenses for other projects incorporated by Bottleneck are now reproduced in full in separate files in the ``LICENSES/`` directory (eg, ``LICENSES/NUMPY_LICENSE``)
- All licenses have been updated. Notably, setuptools is now MIT licensed and no longer under the ambiguous dual PSF/Zope license.
- Bottleneck now uses :pep:`518` for specifying build dependencies, with per Python version specifications
Enhancements
- Remove ``numpydoc`` package from Bottleneck source distribution
- :func:`bottleneck.slow.reduce.nansum` and :func:`bottleneck.slow.reduce.ss` now longer coerce output to have the same dtype as input
- Test (tox, travis, appveyor) against latest ``numpy`` (in conda)
- Performance benchmarking also available via ``asv``
- ``versioneer`` now used for versioning
- Test suite now uses ``pytest`` as ``nose`` is deprecated
- ``python setup.py build_ext --inplace`` is now incremental
- ``python setup.py clean`` now cleans all artifacts
- Compiler feature support now identified by testing rather than hardcoding
- The ``BN_OPT_3`` macro allows selective use of ``-O3`` at the function level
- Contributors are now automatically cited in the release notes
Performance
- Speed up :func:`bottleneck.reduce.anynan` and :func:`bottleneck.reduce.allnan` by 2x via ``BN_OPT_3``
- All functions covered by ``asv`` benchmarks
- :func:`bottleneck.nonreduce.replace` speedup of 4x via more explicit typing
- :func:`bottleneck.reduce.median` up to 2x faster for Fortran-ordered arrays
Bug Fixes
- Documentation fails to build on Python 3
- :func:`bottleneck.benchmark.bench` crashes on python 3.6.3, numpy 1.13.3
- :func:`bottleneck.nonreduce_axis.push` raises when :code:`n=None` is explicitly passed
- :func:`bottleneck.reduce.nansum` wrong output when :code:`a = np.ones((2, 2))[..., np.newaxis]`
same issue of other reduce functions
- Silenced FutureWarning from NumPy in the slow version of move functions
- Installing bottleneck onto a system that does not already have Numpy
- Memory leaked when input was not a NumPy array
- Tautological comparison in :func:`bottleneck.move.move_rank` removed
Cleanup
- The ``ez_setup.py`` module is no longer packaged
- Building documentation is now self-contained in ``make doc``
- Codebase now ``flake8`` compliant and run on every commit
- Codebase now uses ``black`` for autoformatting
0.9.18:
clarify that 0.9.17 was the final version to support Py2.7
0.9.17:
add 3.8 to travis config
0.9.16:
auto-run codecov only if numpy is installed
Version 0.49.0:
This release is very large in terms of code changes. Large scale removal of unsupported Python and NumPy versions has taken place along with a significant amount of refactoring to simplify the Numba code base to make it easier for contributors. Numba’s intermediate representation has also undergone some important changes to solve a number of long standing issues. In addition some new features have been added and a large number of bugs have been fixed!
IMPORTANT: In this release Numba’s internals have moved about a lot. A backwards compatibility “shim” is provided for this release so as to not immediately break projects using Numba’s internals. If a module is imported from a moved location the shim will issue a deprecation warning and suggest how to update the import statement for the new location. The shim will be removed in 0.50.0!
Highlights of core feature changes include:
Removal of all Python 2 related code and also updating the minimum supported Python version to 3.6, the minimum supported NumPy version to 1.15 and the minimum supported SciPy version to 1.0.
Refactoring of the Numba code base. The code is now organised into submodules by functionality. This cleans up Numba’s top level namespace.
Introduction of an ir.Del free static single assignment form for Numba’s intermediate representation
An OpenMP-like thread masking API has been added for use with code using the parallel CPU backends
For the CUDA target, all kernel launches now require a configuration, this preventing accidental launches of kernels with the old default of a single thread in a single block. The hard-coded autotuner is also now removed, such tuning is deferred to CUDA API calls that provide the same functionality
The CUDA target also gained an External Memory Management plugin interface to allow Numba to use another CUDA-aware library for all memory allocations and deallocations
The Numba Typed List container gained support for construction from iterables
Experimental support was added for first-class function types

v0.15.1:
This release brings many new features such as :py:meth:`Dataset.weighted` methods for weighted array
reductions, a new jupyter repr by default, and the start of units integration with pint. There's also
the usual batch of usability improvements, documentation additions, and bug fixes.
Breaking changes
- Raise an error when assigning to the ``.values`` or ``.data`` attribute of
dimension coordinates i.e. ``IndexVariable`` objects. This has been broken since
v0.12.0. Please use :py:meth:`DataArray.assign_coords` or :py:meth:`Dataset.assign_coords`
instead.
New Features
- Weighted array reductions are now supported via the new :py:meth:`DataArray.weighted`
and :py:meth:`Dataset.weighted` methods. See :ref:`comput.weighted`.
- The new jupyter notebook repr (``Dataset._repr_html_`` and
``DataArray._repr_html_``) (introduced in 0.14.1) is now on by default. To
disable, use ``xarray.set_options(display_style="text")``.
- Added support for :py:class:`pandas.DatetimeIndex`-style rounding of
``cftime.datetime`` objects directly via a :py:class:`CFTimeIndex` or via the
:py:class:`~core.accessor_dt.DatetimeAccessor`.
- Support new h5netcdf backend keyword `phony_dims` (available from h5netcdf
v0.8.0 for :py:class:`~xarray.backends.H5NetCDFStore`.
- Add partial support for unit aware arrays with pint.
- :py:meth:`Dataset.groupby` and :py:meth:`DataArray.groupby` now raise a
`TypeError` on multiple string arguments. Receiving multiple string arguments
often means a user is attempting to pass multiple dimensions as separate
arguments and should instead pass a single list of dimensions.
- :py:func:`map_blocks` can now apply functions that add new unindexed dimensions.
- An ellipsis (``...``) is now supported in the ``dims`` argument of
:py:meth:`Dataset.stack` and :py:meth:`DataArray.stack`, meaning all
unlisted dimensions, similar to its meaning in :py:meth:`DataArray.transpose`.
- :py:meth:`Dataset.where` and :py:meth:`DataArray.where` accept a lambda as a
first argument, which is then called on the input; replicating pandas' behavior.
- ``skipna`` is available in :py:meth:`Dataset.quantile`, :py:meth:`DataArray.quantile`,
:py:meth:`core.groupby.DatasetGroupBy.quantile`, :py:meth:`core.groupby.DataArrayGroupBy.quantile`
Bug fixes
- Fix :py:meth:`Dataset.interp` when indexing array shares coordinates with the
indexed variable
- Fix recombination of groups in :py:meth:`Dataset.groupby` and
:py:meth:`DataArray.groupby` when performing an operation that changes the
size of the groups along the grouped dimension. By `Eric Jansen
<https://github.com/ej81>`_.
- Fix use of multi-index with categorical values
- Fix alignment with ``join="override"`` when some dimensions are unindexed.
- Fix :py:meth:`Dataset.swap_dims` and :py:meth:`DataArray.swap_dims` producing
index with name reflecting the previous dimension name instead of the new one
- Use ``dask_array_type`` instead of ``dask_array.Array`` for type
checking.
- :py:func:`concat` can now handle coordinate variables only present in one of
the objects to be concatenated when ``coords="different"``.
- xarray now respects the over, under and bad colors if set on a provided colormap.
- :py:func:`coarsen` now respects ``xr.set_options(keep_attrs=True)``
to preserve attributes. :py:meth:`Dataset.coarsen` accepts a keyword
argument ``keep_attrs`` to change this setting.
:pull:`3801`) By `Andrew Thomas <https://github.com/amcnicho>`_.
- Delete associated indexes when deleting coordinate variables.
- Fix :py:meth:`xarray.core.dataset.Dataset.to_zarr` when using `append_dim` and `group`
simultaneously.
- Fix html repr on :py:class:`Dataset` with non-string keys
Documentation
- Fix documentation of :py:class:`DataArray` removing the deprecated mention
that when omitted, `dims` are inferred from a `coords`-dict.
- Improve the :py:func:`where` docstring.
- Update the installation instructions: only explicitly list recommended dependencies
Internal Changes
- Remove the internal ``import_seaborn`` function which handled the deprecation of
the ``seaborn.apionly`` entry point
- Don't test pint integration in combination with datetime objects.
- Change test_open_mfdataset_list_attr to only run with dask installed
- Preserve the ability to index with ``method="nearest"`` with a
:py:class:`CFTimeIndex` with pandas versions greater than 1.0.1
- Greater flexibility and improved test coverage of subtracting various types
of objects from a :py:class:`CFTimeIndex`. By `Spencer Clark
<https://github.com/spencerkclark>`_.
- Update Azure CI MacOS image, given pending removal.
- Remove xfails for scipy 1.0.1 for tests that append to netCDF files
- Remove conversion to :py:class:`pandas.Panel`, given its removal in pandas
in favor of xarray's objects.
v0.15.0:
This release brings many improvements to xarray's documentation: our examples are now binderized notebooks (`click here <https://mybinder.org/v2/gh/pydata/xarray/master?urlpath=lab/tree/doc/examples/weather-data.ipynb>`_)
and we have new example notebooks from our SciPy 2019 sprint (many thanks to our contributors!).
This release also features many API improvements such as a new
:py:class:`~core.accessor_dt.TimedeltaAccessor` and support for :py:class:`CFTimeIndex` in
:py:meth:`~DataArray.interpolate_na`); as well as many bug fixes.
Breaking changes
- Bumped minimum tested versions for dependencies:
- numpy 1.15
- pandas 0.25
- dask 2.2
- distributed 2.2
- scipy 1.3
- Remove ``compat`` and ``encoding`` kwargs from ``DataArray``, which
have been deprecated since 0.12.
Instead, specify the ``encoding`` kwarg when writing to disk or set
the :py:attr:`DataArray.encoding` attribute directly.
- :py:func:`xarray.dot`, :py:meth:`DataArray.dot`, and the ``@`` operator now
use ``align="inner"`` (except when ``xarray.set_options(arithmetic_join="exact")``;
New Features
- Implement :py:meth:`DataArray.pad` and :py:meth:`Dataset.pad`.
- :py:meth:`DataArray.sel` and :py:meth:`Dataset.sel` now support :py:class:`pandas.CategoricalIndex`.
- Support using an existing, opened h5netcdf ``File`` with
:py:class:`~xarray.backends.H5NetCDFStore`. This permits creating an
:py:class:`~xarray.Dataset` from a h5netcdf ``File`` that has been opened
using other means
- Implement ``median`` and ``nanmedian`` for dask arrays. This works by rechunking
to a single chunk along all reduction axes.
- :py:func:`~xarray.concat` now preserves attributes from the first Variable.
- :py:meth:`Dataset.quantile`, :py:meth:`DataArray.quantile` and ``GroupBy.quantile``
now work with dask Variables.
- Added the ``count`` reduction method to both :py:class:`~core.rolling.DatasetCoarsen`
and :py:class:`~core.rolling.DataArrayCoarsen` objects.
- Add ``meta`` kwarg to :py:func:`~xarray.apply_ufunc`;
this is passed on to :py:func:`dask.array.blockwise`.
- Add ``attrs_file`` option in :py:func:`~xarray.open_mfdataset` to choose the
source file for global attributes in a multi-file dataset
:pull:`3498`). By `Julien Seguinot <https://github.com/juseg>`_.
- :py:meth:`Dataset.swap_dims` and :py:meth:`DataArray.swap_dims`
now allow swapping to dimension names that don't exist yet.
- Extend :py:class:`~core.accessor_dt.DatetimeAccessor` properties
and support ``.dt`` accessor for timedeltas
via :py:class:`~core.accessor_dt.TimedeltaAccessor`
- Improvements to interpolating along time axes
- Support :py:class:`CFTimeIndex` in :py:meth:`DataArray.interpolate_na`
- define 1970-01-01 as the default offset for the interpolation index for both
:py:class:`pandas.DatetimeIndex` and :py:class:`CFTimeIndex`,
- use microseconds in the conversion from timedelta objects to floats to avoid
overflow errors.
Bug fixes
- Applying a user-defined function that adds new dimensions using :py:func:`apply_ufunc`
and ``vectorize=True`` now works with ``dask > 2.0``.
- Fix :py:meth:`~xarray.combine_by_coords` to allow for combining incomplete
hypercubes of Datasets
- Fix :py:func:`~xarray.combine_by_coords` when combining cftime coordinates
which span long time intervals
- Fix plotting with transposed 2D non-dimensional coordinates.
- :py:meth:`plot.FacetGrid.set_titles` can now replace existing row titles of a
:py:class:`~xarray.plot.FacetGrid` plot. In addition :py:class:`~xarray.plot.FacetGrid` gained
two new attributes: :py:attr:`~xarray.plot.FacetGrid.col_labels` and
:py:attr:`~xarray.plot.FacetGrid.row_labels` contain :py:class:`matplotlib.text.Text` handles for both column and
row labels. These can be used to manually change the labels.
- Fix issue with Dask-backed datasets raising a ``KeyError`` on some computations involving :py:func:`map_blocks`
- Ensure :py:meth:`Dataset.quantile`, :py:meth:`DataArray.quantile` issue the correct error
when ``q`` is out of bounds
- Fix regression in xarray 0.14.1 that prevented encoding times with certain
``dtype``, ``_FillValue``, and ``missing_value`` encodings
- Raise an error when trying to use :py:meth:`Dataset.rename_dims` to
rename to an existing name
- :py:meth:`Dataset.rename`, :py:meth:`DataArray.rename` now check for conflicts with
MultiIndex level names.
- :py:meth:`Dataset.merge` no longer fails when passed a :py:class:`DataArray` instead of a :py:class:`Dataset`.
- Fix a regression in :py:meth:`Dataset.drop`: allow passing any
iterable when dropping variables
- Fixed errors emitted by ``mypy --strict`` in modules that import xarray.
- Allow plotting of binned coordinates on the y axis in :py:meth:`plot.line`
and :py:meth:`plot.step` plots
- setuptools is now marked as a dependency of xarray
Documentation
- Switch doc examples to use `nbsphinx <https://nbsphinx.readthedocs.io>`_ and replace
``sphinx_gallery`` scripts with Jupyter notebooks.

Regional Ocean Modeling System (ROMS) ocean hydrodynamic model output.
- Added :doc:`example notebook <examples/ERA5-GRIB-example>` demonstrating the visualization of
ERA5 GRIB data.

vectorization of a 1D function using :py:func:`apply_ufunc` , dask and numba.
- Added example for :py:func:`~xarray.map_blocks`.
Internal Changes
- Make sure dask names change when rechunking by different chunk sizes. Conversely, make sure they
stay the same when rechunking by the same chunk size.
- 2x to 5x speed boost (on small arrays) for :py:meth:`Dataset.isel`,
:py:meth:`DataArray.isel`, and :py:meth:`DataArray.__getitem__` when indexing by int,
slice, list of int, scalar ndarray, or 1-dimensional ndarray.
- Removed internal method ``Dataset._from_vars_and_coord_names``,
which was dominated by ``Dataset._construct_direct``.
- Replaced versioneer with setuptools-scm. Moved contents of setup.py to setup.cfg.
Removed pytest-runner from setup.py, as per deprecation notice on the pytest-runner
project.
- Use of isort is now enforced by CI.

On macOS 10.13 (at least), unpacking the distfile as root results in
files that have strange permissions, including group/world writable
and executable. The upstream distfile has these, but extracting on
other systems or on mac not as root applies some sort of umask. On
Darwin only, chmod these spurious bits away. Tested to work as
non-root and root on macOS 10.13, and by inspection will not affect
!macOS.
No arpack release has been published by Rice University for many years, and
arpack-ng aims to provide a common repository of community fixes with a
testsuite.
Harmbase is a database application for managing harmonic constants.
It is not "plug and play" software. It's not designed to be useful
to someone who does not know how to hack Ruby code or write
interactive SQL queries.
congen is a C++ library for generating the speeds, equilibrium arguments,
and node factors of Darwin-style tidal constituents more or less as defined
in SP 98:
Manual of Harmonic Analysis and Prediction of Tides. Special Publication
No. 98, Revised (1940) Edition (reprinted 1958 with corrections;
reprinted again 1994). United States Government Printing Office, 1994.
Additionally, libcongen provides limited support for approximating
Doodson-style tidal constituents within the infrastructure of the former.
The Doodson approach is discussed in the following publication:
Foreman, M.G.G., 1977. Manual for Tidal Heights Analysis and Prediction.
Pacific Marine Science Report 77-10, Institute of Ocean Sciences,
Patricia Bay, Sidney, B.C. (2004 revision).
The Congen header file is intended to be self-documenting with regards to use
of the interface, assuming that one has access to SP 98 and a general
understanding of the subject matter.
This project started as a joint project between Debian, Octave and
Scilab in order to provide a common and maintained version of arpack,
as no single release has been published by Rice university for the
last few years and many software (Octave, Scilab, R, Matlab...) forked
it and implemented their own modifications.
Have switched to the CMAKE build and enabled tests.
make test passes all (with one patch pushed upstream)

Implements an approximate string matching version of R's native
'match' function. Can calculate various string distances based on
edits (Damerau-Levenshtein, Hamming, Levenshtein, optimal sting
alignment), qgrams (q- gram, cosine, jaccard distance) or heuristic
metrics (Jaro, Jaro-Winkler). An implementation of soundex is provided
as well. Distances can be computed between character vectors while
taking proper care of encoding or between integer vectors representing
generic sequences. This package is built for speed and runs in
parallel by using 'openMP'. An API for C or C++ is exposed as well.
# ellipsis 0.3.0
* `check_dots_used()`, `check_dots_unnamed()`, and `check_dots_empty()` gain an
`action` argument, to specify if they should error, warn, message or signal
when the dots meet the condition.
Changelog:
ixion 0.15.0
* fill_down_cells() method has been added to model_context, to fill duplicate
values downward from an arbitrary cell position. For now, it always
duplicate the value of the source cell; cell value enumerations are not
supported. Also, filling down of formula cells is not yet supported.
* cell iterator has been aded to model_context, for efficient horizontal and
vertical iterations of cell values in an arbitrary range within a sheet.
* improved the cmake-based build, with all test cases integrated.
* switched to spdlog for compile-time debug log outputs.
* improved performance by removing repeated fetching of each formula
cell prior to interpretation.
* reworked topological sorting of formula cells to avoid having to
unnecessarily build dependency relations twice; once during the
dirty cell determination and twice prior to interpretation of
formula cells. The new code performs topological sorting during the
dirty cell determination phase.
* reworked the cell reference tracker to use R-tree. This allows more
accurate tracking of references involving grouped formulas.
* fixed a resource leak with dynamic loading of compute engine modules.
Version 0.48.0
This release is particularly small as it was present to catch anything that missed the 0.47.0 deadline (the deadline deliberately coincided with the end of support for Python 2.7). The next release will be considerably larger.
The core changes in this release are dominated by the start of the clean up needed for the end of Python 2.7 support, improvements to the CUDA target and support for numerous additional unicode string methods.

Changes:
- Fix a regression in 1.5 that allowed expressions to compare equal to
strings, and caused == to call str() on the other object.
- Avoid using scipy versions of numpy functions, which are deprecated,
in lambdify.
Take MAINTAINERship.
Changes:
- The np.testing.utils functions have been updated from
1.19.0-dev0. This improves the function documentation and error
messages as well extending the assert_array_compare function to
additional types.
- Allow matmul (@) to work with object arrays.
- Fix regression in matmul (@) for boolean types.
- Array comparison assertions include maximum differences.
pkglint -r --network --only "migrate"
As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.
Breaking changes:
- Deprecate is_EmptySet in favor of is_empty.
- Lambda now requires a tuple rather than a list for the signature
argument (non-tuple iterables are deprecated)
- Eq(expr) now raises ValueError. Eq(expr, 0) should be used
instead.
- Refactory of the units module. Scale factors and dimensions are now
both global and relative to single unit systems.
- get_dixon_matrix() now computes only the necessary monomials for the
Dixon matrix.
- The ProductSet of no sets is no longer the empty set. Instead is the
set consisting of the empty tuple.
- Deprecated tensorhead() and tensorsymmetry() static methods.
- Rational, irrational, transcendental and algebraic now imply finite
in the assumptions system. This means that all symbols declared as
rational, integer, odd etc are now automatically assumed finite.
- In the (old) assumptions, complex=True now implies finite=True. Note
that the default assumption for Symbol is complex=None, which allows
for the possibility for it to be infinite.
- The assumptions system is changed so that only finite numbers can be
considered real, positive, negative, nonnegative, nonpositive or
nonzero (since nonzero implies real). This means that any symbol
declared with e.g. real=True is now automatically considered
finite. It also means that infinities can not be considered positive
or negative since they are not real (e.g. oo.is_positive is now
False).
- New assumptions extended_real, extended_positive etc are added that
allow for positive and negative infinity. The equivalent of
Symbol('x', real=True) in version 1.4 is now Symbol('x',
extended_real=True). The equivalent of Symbol('x', negative=False)
is now Symbol('x', extended_negative=False) although it is usually
better to use Symbol('x', nonnegative=True) (which implies both
real=True and finite=True as well). Code that previously checked if
x.is_positive should now be written as if x.is_extended_positive if
it is intended that infinities should be allowed.
- Numbers still compare the same as they do in Python (Float(1) == 1)
except when they appear in an Expression, e.g. x**2.0 != x**2
Changes:
- Add project URLs to setup.py
- fix tests and ctypes code for PyPy
- use npy_intp instead of int for indexing array
- Ignore DeprecationWarning during nose imports
- Fix use-after-free in boolean indexing
- Fix errors in _add_newdocs
- fix byte order reversal for datetime64[ns]
- Use nbytes to also catch empty descr during allocation
- np.array cleared errors occured in PyMemoryView_FromObject
- Fixes for Undefined Behavior Sanitizer (UBSan) errors.
- ensure that casting to/from structured is properly checked.
- fix histogram*d dispatchers
- further fixup to histogram2d dispatcher.
- Replace contextlib.suppress for Python 2.7
- fix compilation of 3rd party modules with Py_LIMITED_API...
- Fix memory leak in dtype from dict contructor
- Document array_function at a higher level.
- add new recfunctions to __all__
- Remove stray print that causes a SystemError on python 3.7
- Pin pytest version to 5.0.1.
- Enable huge pages in all Linux builds
- fix behavior of structured_to_unstructured
Partially based on diff sent by Kai-Uwe Eckhardt in private mail.
v1.2.0
-- A huge refactoring of the library happened - renaming,
deprecating and replacing existing functions by improved API's.
All deprecated functions, macros and symbols are only marked as such
so this version is still API and ABI compatible to v1.x.
-- Daniel Mendler was pushing for those changes and contributing a load of patches,
refactorings, code reviews and whatnotelse.
-- Christoph Zurnieden re-worked internals of the library, improved the performance,
did code reviews and wrote documentation.
-- Francois Perrad did some refactoring and took again care of linting the sources and
provided all fixes.
-- Jan Nijtmans, Karel Miko and Joachim Breitner contributed various patches.
-- Private symbols can now be hidden for the shared library builds, disabled by default.
-- All API's follow a single code style, are prefixed the same etc.
-- Unified, safer and improved API's
-- Less magic numbers - return values (where appropriate) and most flags are now enums,
this was implemented in a backwards compatible way where return values were int.
-- API's with return values are now by default marked as "warn on unsused result", this
can be disabled if required (which will most likely hide bugs), c.f. MP_WUR in tommath.h
-- Provide a whole set of setters&getters for different primitive types (long, uint32_t, etc.)
-- All those primitive setters are now optimized.
-- It's possible to automatically tune the cutoff values for Karatsuba&Toom-Cook
-- The custom allocators which were formerly known as XMALLOC(), XFREE() etc. are now available
as MP_MALLOC(), MP_REALLOC(), MP_CALLOC() and MP_FREE(). MP_REALLOC() and MP_FREE() now also
provide the allocated size to ease the usage of simple allocators without tracking.
-- Building is now also possible with MSVC 2015, 2017 and 2019 (use makefile.msvc)
-- Added mp_decr() and mp_incr()
-- Added mp_log_u32()
-- Improved prime-checking
-- Improved Toom-Cook multiplication
-- Removed the LTM book (`make docs` now builds the user manual)
Utilities for dealing with IEEE floating point numbers, ported from
the Tango math library; approximate and exact equality comparisons for
general types.
pkglint --only "https instead of http" -r -F
With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.
This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.
Highlights:
* Logic expressions with relations can now be simplifed in a better
way which has impact on e.g. simplification of piecewise
expressions.
* The MathML Presentation printer has seen a major improvement with
support configuration and about a hundred new functions.
* Union and Intersection have been improved to, among other
improvements, support Python sets.
* The test procedure has been changed to include code coverage and
code quality checks leading to a number of issues being identified
and removed.
* Unicode support, especially for Python 2.7, has been improved.
* subs and Subs have been improved in a number of ways.
* SymPy objects now renders as LaTeX automatically in Jupyter
notebooks. init_printing is still required to LaTeX render non-SymPy
objects such as lists of expressions or Python ints.
Version 0.47.0

Provides a wide array of (semi)groupoids and operations for working with them.
A Semigroupoid is a Category without the requirement of identity arrows
for every object in the category.
A Category is any Semigroupoid for which the Yoneda lemma holds.
When working with comonads you often have the <*> portion of an Applicative,
but not the pure. This was captured in Uustalu and Vene's
"Essence of Dataflow Programming" in the form of the ComonadZip class
in the days before Applicative. Apply provides a weaker invariant,
but for the comonads used for data flow programming
(found in the streams package), this invariant is preserved.
Applicative function composition forms a semigroupoid.
Similarly many structures are nearly a comonad, but not quite,
for instance lists provide a reasonable extend operation in the form of tails,
but do not always contain a value.
Formally, the class Profunctor represents a profunctor from Hask ->
Hask.
Intuitively it is a bifunctor where the first argument is
contravariant and the second argument is covariant.
