Version 0.52.0
--------------
In development
Version 0.51.2 (September 2, 2020)
----------------------------------
This is a bugfix release for 0.51.1. It fixes a critical performance bug in the
CFG back edge computation algorithm that leads to exponential time complexity
arising in compilation for use cases with certain pathological properties.
* PR #6195: PR 6187 Continue. Don't visit already checked successors
Authors:
* Graham Markall
* Siu Kwan Lam (core dev)
Version 0.51.1 (August 26, 2020)
--------------------------------
This is a bugfix release for 0.51.0, it fixes a critical bug in caching, another
critical bug in the CUDA target initialisation sequence and also fixes some
compile time performance regressions:
* PR #6141: Fix #6130 objmode cache segfault
* PR #6146: Fix compilation slowdown due to controlflow analysis
* PR #6147: CUDA: Don't make a runtime call on import
* PR #6153: Fix for #6151. Make UnicodeCharSeq into str for comparison.
* PR #6168: Fix Issue #6167: Failure in test_cuda_submodules
Authors:
* Graham Markall
* Siu Kwan Lam (core dev)
* Stuart Archibald (core dev)
Version 0.51.0 (August 12, 2020)
--------------------------------
This release continues to add new features to Numba and also contains a
significant number of bug fixes and stability improvements.
Highlights of core feature changes include:
* The compilation chain is now based on LLVM 10 (Valentin Haenel).
* Numba has internally switched to prefer non-literal types over literal ones so
as to reduce function over-specialisation, this with view of speeding up
compile times (Siu Kwan Lam).
* On the CUDA target: Support for CUDA Toolkit 11, Ampere, and Compute
Capability 8.0; Printing of ``SASS`` code for kernels; Callbacks to Python
functions can be inserted into CUDA streams, and streams are async awaitable;
Atomic ``nanmin`` and ``nanmax`` functions are added; Fixes for various
miscompilations and segfaults. (mostly Graham Markall; call backs on
streams by Peter Würtz).
Intel also kindly sponsored research and development that lead to some exciting
new features:
* Support for heterogeneous immutable lists and heterogeneous immutable string
key dictionaries. Also optional initial/construction value capturing for all
lists and dictionaries containing literal values (Stuart Archibald).
* A new pass-by-reference mutable structure extension type ``StructRef`` (Siu
Kwan Lam).
* Object mode blocks are now cacheable, with the side effect of numerous bug
fixes and performance improvements in caching. This also permits caching of
functions defined in closures (Siu Kwan Lam).
Deprecations to note:
To align with other targets, the ``argtypes`` and ``restypes`` kwargs to
``@cuda.jit`` are now deprecated, the ``bind`` kwarg is also deprecated.
Further the ``target`` kwarg to the ``numba.jit`` decorator family is
deprecated.

Version 0.50.0 (Jun 10, 2020)
-----------------------------
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.
IMPORTANT: The backwards compatibility shim, that was present in 0.49.x to
accommodate the refactoring of Numba's internals, has been removed. If a module
is imported from a moved location an ``ImportError`` will occur.

Version 0.49.0 (Apr 16, 2020)
-----------------------------
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. (Stuart Archibald).
* Refactoring of the Numba code base. The code is now organised into submodules
by functionality. This cleans up Numba's top level namespace.
(Stuart Archibald).
* Introduction of an ``ir.Del`` free static single assignment form for Numba's
intermediate representation (Siu Kwan Lam and Stuart Archibald).
* An OpenMP-like thread masking API has been added for use with code using the
parallel CPU backends (Aaron Meurer and Stuart Archibald).
* 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
(Graham Markall).
* 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 (Graham Markall).
* The Numba Typed List container gained support for construction from iterables
(Valentin Haenel).
* Experimental support was added for first-class function types
(Pearu Peterson).
Enhancements from user contributed PRs (with thanks!):
* Aaron Meurer added support for thread masking at runtime in #4615.
* Andreas Sodeur fixed a long standing bug that was preventing ``cProfile`` from
working with Numba JIT compiled functions in #4476.

warnings in #5485, #5488, #5498 and partly #5532.
* Ethan Pronovost fixed a problem with the shim erroneously warning for jitclass
use in #5454 and also prevented illegal return values in jitclass ``__init__``
in #5505.

Version 0.48.0 (Jan 27, 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

* #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.

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)
