Version 0.49.0dev
-----------------
In development
Version 0.48.0 (Jan 16, 2020)
-----------------------------
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.
Enhancements from user contributed PRs (with thanks!):
* Brian Wignall fixed more spelling typos in #4998.
* Denis Smirnov added support for string methods ``capitalize`` (#4823),
``casefold`` (#4824), ``swapcase`` (#4825), ``rsplit`` (#4834), ``partition``
(#4845) and ``splitlines`` (#4849).
* Elena Totmenina extended support for string methods ``startswith`` (#4867) and
added ``endswith`` (#4868).
* Eric Wieser made ``type_callable`` return the decorated function itself in
#4760
* Ethan Pronovost added support for ``np.argwhere`` in #4617
* Graham Markall contributed a large number of CUDA enhancements and fixes,
namely:
* #5068: Remove Python 3.4 backports from utils
* #4975: Make ``device_array_like`` create contiguous arrays (Fixes #4832)
* #5023: Don't launch ForAll kernels with 0 elements (Fixes #5017)
* #5016: Fix various issues in CUDA library search (Fixes #4979)
* #5014: Enable use of records and bools for shared memory, remove ddt, add
additional transpose tests
* #4964: Fix #4628: Add more appropriate typing for CUDA device arrays
* #5007: test_consuming_strides: Keep dev array alive
* #4997: State that CUDA Toolkit 8.0 required in docs
* James Bourbeau added the Python 3.8 classifier to setup.py in #5027.
* John Kirkham added a clarification to the ``__cuda_array_interface__``
documentation in #5049.
* Leo Fang Fixed an indexing problem in ``dummyarray`` in #5012.
* Marcel Bargull fixed a build and test issue for Python 3.8 in #5029.
* Maria Rubtsov added support for string methods ``isdecimal`` (#4842),
``isdigit`` (#4843), ``isnumeric`` (#4844) and ``replace`` (#4865).
General Enhancements:
* PR #4760: Make type_callable return the decorated function

Version 0.47.0 (Jan 2, 2020)
-----------------------------
This release expands the capability of Numba in a number of important areas and
is also significant as it is the last major point release with support for
Python 2 and Python 3.5 included. The next release (0.48.0) will be for Python
3.6+ only! (This follows NumPy's deprecation schedule as specified in
`NEP 29 <https://numpy.org/neps/nep-0029-deprecation_policy.html>`_.)
Highlights of core feature changes include:
* Full support for Python 3.8 (Siu Kwan Lam)
* Opt-in bounds checking (Aaron Meurer)
* Support for ``map``, ``filter`` and ``reduce`` (Stuart Archibald)
Intel also kindly sponsored research and development that lead to some exciting
new features:
* Initial support for basic ``try``/``except`` use (Siu Kwan Lam)
* The ability to pass functions created from closures/lambdas as arguments
(Stuart Archibald)
* ``sorted`` and ``list.sort()`` now accept the ``key`` argument (Stuart
Archibald and Siu Kwan Lam)
* A new compiler pass triggered through the use of the function
``numba.literal_unroll`` which permits iteration over heterogeneous tuples
and constant lists of constants. (Stuart Archibald)
Enhancements from user contributed PRs (with thanks!):
* Ankit Mahato added a reference to a new talk on Numba at PyCon India 2019 in
#4862
* Brian Wignall kindly fixed some spelling mistakes and typos in #4909
* Denis Smirnov wrote numerous methods to considerable enhance string support
including:
* ``str.rindex()`` in #4861
* ``str.isprintable()`` in #4836
* ``str.index()`` in #4860
* ``start/end`` parameters for ``str.find()`` in #4866
* ``str.isspace()`` in #4835
* ``str.isidentifier()`` #4837
* ``str.rpartition()`` in #4841
* ``str.lower()`` and ``str.islower()`` in #4651
* Elena Totmenina implemented both ``str.isalnum()``, ``str.isalpha()`` and

Version 0.46.0
--------------
This release significantly reworked one of the main parts of Numba, the compiler
pipeline, to make it more extensible and easier to use. The purpose of this was
to continue enhancing Numba's ability for use as a compiler toolkit. In a
similar vein, Numba now has an extension registration mechanism to allow other
Numba-using projects to automatically have their Numba JIT compilable functions
discovered. There were also a number of other related compiler toolkit
enhancement added along with some more NumPy features and a lot of bug fixes.
This release has updated the CUDA Array Interface specification to version 2,
which clarifies the `strides` attribute for C-contiguous arrays and specifies
the treatment for zero-size arrays. The implementation in Numba has been
changed and may affect downstream packages relying on the old behavior
(see issue #4661).
Enhancements from user contributed PRs (with thanks!):
* Aaron Meurer fixed some Python issues in the code base in #4345 and #4341.
* Ashwin Srinath fixed a CUDA performance bug via #4576.
* Ethan Pronovost added support for triangular indices functions in #4601 (the
NumPy functions ``tril_indices``, ``tril_indices_from``, ``triu_indices``, and
``triu_indices_from``).
* Gerald Dalley fixed a tear down race occurring in Python 2.
* Gregory R. Lee fixed the use of deprecated ``inspect.getargspec``.
* Guilherme Leobas contributed five PRs, adding support for ``np.append`` and
``np.count_nonzero`` in #4518 and #4386. The typed List was fixed to accept
unsigned integers in #4510. #4463 made a fix to NamedTuple internals and #4397
updated the docs for ``np.sum``.
* James Bourbeau added a new feature to permit the automatic application of the
`jit` decorator to a whole module in #4331. Also some small fixes to the docs
and the code base were made in #4447 and #4433, and a fix to inplace array
operation in #4228.

--------------
IMPORTANT: In this release a few significant deprecations (and some less
significant ones) are being made, users are encouraged to read the related
documentation.
General enhancements in this release include:
- Numba is backed by LLVM 8 on all platforms apart from ppc64le, which, due to
bugs, remains on the LLVM 7.x series.
- Numba's dictionary support now includes type inference for keys and values.
- The .view() method now works for NumPy scalar types.
- Newly supported NumPy functions added: np.delete, np.nanquantile, np.quantile,
np.repeat, np.shape.
In addition considerable effort has been made to fix some long standing bugs and
a large number of other bugs, the "Fixes" section is very large this time!
Enhancements from user contributed PRs (with thanks!):
- Max Bolingbroke added support for the selective use of ``fastmath`` flags in
#3847.
- Rob Ennis made min() and max() work on iterables in #3820 and added
np.quantile and np.nanquantile in #3899.
- Sergey Shalnov added numerous unicode string related features, zfill in #3978,
ljust in #4001, rjust and center in #4044 and strip, lstrip and rstrip in
#4048.
- Guilherme Leobas added support for np.delete in #3890
- Christoph Deil exposed the Numba CLI via ``python -m numba`` in #4066 and made
numerous documentation fixes.
- Leo Schwarz wrote the bulk of the code for jitclass default constructor
arguments in #3852.
- Nick White enhanced the CUDA backend to use min/max PTX instructions where
possible in #4054.

jitclass in #3861.

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.
* PR #3826: NumPy 1.16 support
* PR #3850: Refactor np.interp
* PR #3883: Rewrite pruned conditionals as their evaluated constants.

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
NOTE:
The vast majority of NumPy 1.16 behaviour is supported, however
``datetime`` and ``timedelta`` use involving ``NaT`` matches the behaviour
present in earlier release. The ufunc suite has not been extending to
accommodate the two new time computation related additions present in NumPy
1.16. In addition the functions ``ediff1d`` and ``interp`` have known minor
issues in replicating outputs exactly when ``NaN``'s occur in certain input
patterns.
