This is a major Numba release. Numba now uses towncrier to create the release \ 
notes, so please find a summary of all noteworthy items below.
Highlights
Added towncrier

This PR adds towncrier as a GitHub workflow for checking release notes. From \ 
this PR onwards every PR made in Numba will require a appropriate release note \ 
associated with it. The reviewer may decide to skip adding release notes in \ 
smaller PRs with minimal impact by addition of a skip_release_notes label to the \ 
PR.

(PR-#8792)
The minimum supported NumPy version is 1.22.

Following NEP-0029, the minimum supported NumPy version is now 1.22.

(PR-#9093)
Add support for NumPy 1.25

Extend Numba to support new and changed features released in NumPy 1.25.

(PR-#9011)
Remove NVVM 3.4 and CTK 11.0 / 11.1 support

Support for CUDA toolkits < 11.2 is removed.

(PR-#9040)
Removal of Windows 32-bit Support

This release onwards, Numba has discontinued support for Windows 32-bit \ 
operating systems.

(PR-#9083)
The minimum llvmlite version is now 0.41.0.

The minimum required version of llvmlite is now version 0.41.0.

(PR-#8916)
Added RVSDG-frontend

This PR is a preliminary work on adding a RVSDG-frontend for processing \ 
bytecode. RVSDG (Regionalized Value-State Dependence Graph) allows us to have a \ 
dataflow-centric view instead of a traditional SSA-CFG view. This allows us to \ 
simplify the compiler in the future.

(PR-#9012)
New Features
numba.experimental.jitclass gains support for __*matmul__ methods.

numba.experimental.jitclass now has support for the following methods:

    __matmul__

    __imatmul__

    __rmatmul__

(PR-#8892)
numba.experimental.jitclass gains support for reflected “dunder” methods.

numba.experimental.jitclass now has support for the following methods:

    __radd__

    __rand_

    __rfloordiv__

    __rlshift__

    __ror_

    __rmod_

    __rmul_

    __rpow_

    __rrshift_

    __rsub_

    __rtruediv_

    __rxor_

(PR-#8906)
Add support for value max to NUMBA_OPT.

The optimisation level that Numba applies when compiling can be set through the \ 
environment variable NUMBA_OPT. This has historically been a value between 0 and \ 
3 (inclusive). Support for the value max has now been added, this is a \ 
Numba-specific optimisation level which indicates that the user would like Numba \ 
to try running the most optimisation possible, potentially trading a longer \ 
compilation time for better run-time performance. In practice, use of the max \ 
level of optimisation may or may not benefit the run-time or compile-time \ 
performance of user code, but it has been added to present an easy to access \ 
option for users to try if they so wish.

(PR-#9094)
Improvements
Updates to numba.core.pythonapi.

Support for Python C-API functions PyBytes_AsString and PyBytes_AsStringAndSize \ 
is added to numba.core.pythonapi.PythonAPI as bytes_as_string and \ 
bytes_as_string_and_size methods respectively.

(PR-#8462)
Support for isinstance is now non-experimental.

Support for the isinstance built-in function has moved from being considered an \ 
experimental feature to a fully supported feature.

(PR-#8911)
NumPy Support
All modes are supported in numpy.correlate and numpy.convolve.

All values for the mode argument to numpy.correlate and numpy.convolve are now \ 
supported.

(PR-#7543)
@vectorize accommodates arguments implementing __array_ufunc__.

Universal functions (ufuncs) created with numba.vectorize will now respect \ 
arguments implementing __array_ufunc__ (NEP-13) to allow pre- and \ 
post-processing of arguments and return values when the ufunc is called from the \ 
interpreter.

(PR-#8995)
Added support for np.geomspace function.

This PR improves on #4074 by adding support for np.geomspace. The current \ 
implementation only supports scalar start and stop parameters.

(PR-#9068)
Added support for np.vsplit, np.hsplit, np.dsplit.

This PR improves on #4074 by adding support for np.vsplit, np.hsplit, and np.dsplit.

(PR-#9082)

functions polyadd, polysub, polymul from np.polynomial.polynomial.

Support is added for np.polynomial.polyutils.trimseq, \ 
np.polynomial.polynomial.polyadd, np.polynomial.polynomial.polysub, \ 
np.polynomial.polynomial.polymul.

(PR-#9087)
Added support for np.diagflat function.

Support is added for numpy.diagflat.

(PR-#9113)
Added support for np.resize function.

target. Namely:

    numpy.bitwise_and

    numpy.bitwise_or

    numpy.bitwise_not

    numpy.bitwise_xor

    numpy.invert

    numpy.left_shift

    numpy.right_shift

(PR-#8974)
Add support for the latest CUDA driver codes.

Support is added for the latest set of CUDA driver codes.

(PR-#8988)
Add NumPy comparison ufunc in CUDA

this PR adds support for comparison ufuncs for the CUDA target (eg. \ 
numpy.greater, numpy.greater_equal, numpy.less_equal, etc.).

(PR-#9007)
Report absolute path of libcuda.so on Linux

numba -s now reports the absolute path to libcuda.so on Linux, to aid \ 
troubleshooting driver issues, particularly on WSL2 where a Linux driver can \ 
incorrectly be installed in the environment.

(PR-#9034)
Add debuginfo support to nvdisasm output.

Support is added for debuginfo (source line and inlining information) in \ 
functions that make calls through nvdisasm. For example the CUDA dispatcher \ 
.inspect_sass method output is now augmented with this information.

(PR-#9035)
Add CUDA SASS CFG Support

This PR adds support for getting the SASS CFG in dot language format. It adds an \ 
inspect_sass_cfg() method to CUDADispatcher and the -cfg flag to the nvdisasm \ 
command line tool.

(PR-#9051)
Support NVRTC using the ctypes binding

NVRTC can now be used when the ctypes binding is in use, enabling float16, and \ 
linking CUDA C / C++ sources without needing the NVIDIA CUDA Python bindings.

(PR-#9086)
Fix CUDA atomics tests with toolkit 12.2

CUDA 12.2 generates slightly different PTX for some atomics, so the relevant \ 
tests are updated to look for the correct instructions when 12.2 is used.

(PR-#9088)
Bug Fixes
Handling of different sized unsigned integer indexes are fixed in \ 
numba.typed.List.

An issue with the order of truncation/extension and casting of unsigned integer \ 
indexes in numba.typed.List has been fixed.

(PR-#7262)
Prevent invalid fusion

This PR fixes an issue in which an array first read in a parfor and later \ 
written in the same parfor would only be classified as used in the parfor. When \ 
a subsequent parfor also used the same array then fusion of the parfors was \ 
happening which should have been forbidden given that that the first parfor was \ 
also writing to the array. This PR treats such arrays in a parfor as being both \ 
used and defined so that fusion will be prevented.

(PR-#7582)
The numpy.allclose implementation now correctly handles default arguments.

The implementation of numpy.allclose is corrected to use TypingError to report \ 
typing errors.

(PR-#8885)
Add type validation to numpy.isclose.

Type validation is added to the implementation of numpy.isclose.

(PR-#8944)
Fix support for overloading dispatcher with non-compatible first-class functions

Fixes an error caused by not handling compilation error during casting of \ 
Dispatcher objects into first-class functions. With the fix, users can now \ 
overload a dispatcher with non-compatible first-class functions. Refer to \ 
https://github.com/numba/numba/issues/9071 for details.

(PR-#9072)
Support dtype keyword argument in numpy.arange with parallel=True

Fixes parfors transformation to support the use of dtype keyword argument in \ 
numpy.arange(..., dtype=dtype).

(PR-#9095)
Fix all @overloads to use parameter names that match public APIs.

Some of the Numba @overloads for functions in NumPy and Python’s built-ins \ 
were written using parameter names that did not match those used in API they \ 
were overloading. The result of this being that calling a function with such a \ 
mismatch using the parameter names as key-word arguments at the call site would \ 
result in a compilation error. This has now been universally fixed throughout \ 
the code base and a unit test is running with a best-effort attempt to prevent \ 
reintroduction of similar mistakes in the future. Fixed functions include:

From Python built-ins:

    complex

    random.seed

    random.gauss

    random.normalvariate

    random.randrange

(PR-#9099)
Changes
Support for @numba.extending.intrinsic(prefer_literal=True)

In the high level extension API, the prefer_literal option is added to the \ 
numba.extending.intrinsic decorator to prioritize the use of literal types when \ 
available. This has the same behavior as in the prefer_literal option in the \ 
numba.extending.overload decorator.

(PR-#6647)
Deprecations
Deprecation of old-style NUMBA_CAPTURED_ERRORS

Added deprecation schedule of NUMBA_CAPTURED_ERRORS=old_style. \ 
NUMBA_CAPTURED_ERRORS=new_style will become the default in future releases. \

Version 0.57.0 (1 May, 2023)

This release continues to add new features, bug fixes and stability improvements \ 
to Numba. Please note that this release contains a significant number of both \ 
deprecation and pending-deprecation notices with view of making it easier to \ 
develop new technology for Numba in the future. Also note that this will be the \ 
last release to support Windows 32-bit packages produced by the Numba team.

Highlights of core dependency upgrades:

    Support for Python 3.11 (minimum is moved to 3.8)

    Support for NumPy 1.24 (minimum is moved to 1.21)

Python language support enhancements:

    Exception classes now support arguments that are not compile time constant.

    The built-in functions hasattr and getattr are supported for compile time \ 
constant attributes.

    The built-in functions str and repr are now implemented similarly to their \ 
Python implementations. Custom __str__ and __repr__ functions can be associated \ 
with types and work as expected.

    Numba’s unicode functionality in str.startswith now supports kwargs start \ 
and end.

    min and max now support boolean types.

    Support is added for the dict(iterable) constructor.

NumPy features/enhancements:

    The largest set of new features is within the numpy.random.Generator \ 
support, the vast majority of commonly used distributions are now supported. \ 
Namely:

        Generator.beta

        Generator.chisquare

        Generator.exponential

        Generator.f

        Generator.gamma

        Generator.geometric

        Generator.integers

        Generator.laplace

        Generator.logistic

        Generator.lognormal

        Generator.logseries

        Generator.negative_binomial

        Generator.noncentral_chisquare

        Generator.noncentral_f

        Generator.normal

        Generator.pareto

        Generator.permutation

        Generator.poisson

        Generator.power

        Generator.random

        Generator.rayleigh

        Generator.shuffle

        Generator.standard_cauchy

        Generator.standard_exponential

        Generator.standard_gamma

        Generator.standard_normal

        Generator.standard_t

        Generator.triangular

        Generator.uniform

        Generator.wald

        Generator.weibull

        Generator.zipf

    The nbytes property on NumPy ndarray types is implemented.

    Nesting of nested-array types is now supported.

    datetime and timedelta types can be cast to int.

    F-order iteration is supported in ufunc generation for increased performance \ 
when using combinations of predominantly F-order arrays.

    The following functions are also now supported:

        np.argpartition

        np.isclose

        np.nan_to_num

        np.new_axis

        np.union1d

Highlights of core changes:

    A large amount of refactoring has taken place to convert many of Numba’s \ 
internal implementations, of both Python and NumPy functions, from the low-level \ 
extension API to the high-level extension API (numba.extending).

    The __repr__ method is supported for Numba types.

    The default target for applicable functions in the extension API \ 
(numba.extending) is now "generic". This means that @overload* and \ 
@intrinsic functions will by default be accepted by both the CPU and CUDA \ 
targets.

    The use of __getitem__ on Numba types is now supported in compiled code. \ 
i.e. types.float64[:, ::1] is now compilable.

Performance:

    The performance of str.find() and str.rfind() has been improved.

    Unicode support for __getitem__ now avoids allocation and returns a view.

    The numba.typed.Dict dictionary now accepts an n_keys option to enable \ 
allocating the dictionary instance to a predetermined initial size (useful to \ 
avoid resizes!).

    The Numba Run-time (NRT) has been improved in terms of performance and safety:

        The NRT internal statistics counters are now off by default (removes \ 
atomic lock contentions).

        Debug cache line filling is off by default.

        The NRT is only compiled once a compilation starts opposed to at \ 
function decoration time, this improves import speed.

        The NRT allocation calls are all made through a “checked” layer by \ 
default.

CUDA:

    New NVIDIA hardware and software compatibility / support:

        Toolkits: CUDA 11.8 and 12, with Minor Version Compatibility for 11.x.

        Packaging: NVIDIA-packaged CUDA toolkit conda packages.

        Hardware: Hopper, Ada Lovelace, and AGX Orin.

    float16 support:

        Arithmetic operations are now fully supported.

        A new method, is_fp16_supported(), and device property, \ 
supports_float16, for checking the availability of float16 support.

    Functionality:

        The high-level extension API is now fully-supported in the CUDA target.

        Eager compilation of multiple signatures, multiple outputs from \ 
generalized ufuncs, and specifying the return type of ufuncs are now supported.

        A limited set of NumPy ufuncs (trigonometric functions) can now be \ 
called inside kernels.

    Lineinfo quality improvement: enabling lineinfo no longer results in any \ 
changes to generated code.

Deprecations:

    The numba.pycc module and everything in it is now pending deprecation.

    The long awaited full deprecation of object mode fall-back is underway. This \ 
change means @jit with no keyword arguments will eventually alias @njit.

    The @generated_jit decorator is deprecated as the Numba extension API \ 
provides a better supported superset of the same functionality, particularly \ 
through @numba.extending.overload.

Version support/dependency changes:

    The setuptools package is now an optional run-time dependency opposed to a \ 
required run-time dependency.

    The TBB threading-layer now requires version 2021.6 or later.

    LLVM 14 is now supported on all platforms via llvmlite.

Version 0.56.1 (NO RELEASE)

The release was skipped due to issues during the release process.
Version 0.56.0 (25 July, 2022)

This release continues to add new features, bug fixes and stability improvements \ 
to Numba. Please note that this will be the last release that has support for \ 
Python 3.7 as the next release series (Numba 0.57) will support Python 3.11! \ 
Also note that, this will be the last release to support linux-32 packages \ 
produced by the Numba team.

Python language support enhancements:

    Previously missing support for large, in-line dictionaries and internal \ 
calls to functions with large numbers of keyword arguments in Python 3.10 has \ 
been added.

    operator.mul now works for list s.

    Literal slices, e.g. slice(1, 10, 2) can be returned from nopython mode \ 
functions.

    The len function now works on dict_keys, dict_values and dict_items .

    Numba’s set implementation now supports reference counted items e.g. strings.

Numba specific feature enhancements:

    The experimental jitclass feature gains support for a large number of \ 
builtin methods e.g. declaring __hash__ or __getitem__ for a jitclass type.

    It’s now possible to use @vectorize on an already @jit family decorated \ 
function.

    Name mangling has been updated to emit compiled function names that exactly \ 
match the function name in Python. This means debuggers, like GDB, can be set to \ 
break directly on Python function names.

    A GDB “pretty printing” support module has been added, when loaded into \ 
GDB Numba’s internal representations of Python/NumPy types are rendered inside \ 
GDB as they would be in Python.

    An experimental option is added to the @jit family decorators to entirely \ 
turn off LLVM’s optimisation passes for a given function (see _dbg_optnone \ 
kwarg in the @jit decorator family).

    A new environment variable is added NUMBA_EXTEND_VARIABLE_LIFETIMES, which \ 
if set will extend the lifetime of variables to the end of their basic block, \ 
this to permit a debugging experience in GDB similar to that found in compiled \ 
C/C++/Fortran code.

NumPy features/enhancements:

    Initial support for passing, using and returning numpy.random.Generator \ 
instances has been added, this currently includes support for the random \ 
distribution.

    The broadcasting functions np.broadcast_shapes and np.broadcast_arrays are \ 
now supported.

    The min and max functions now work with np.timedelta64 and np.datetime64 types.

    Sorting multi-dimensional arrays along the last axis is now supported in \ 
np.sort().

    The np.clip function is updated to accept NumPy arrays for the a_min and \ 
a_max arguments.

    The NumPy allocation routines (np.empty , np.ones etc.) support shape \ 
arguments specified using members of enum.IntEnum s.

    The function np.random.noncentral_chisquare is now supported.

    The performance of functions np.full and np.ones has been improved.

Parallel Accelerator enhancements:

    The parallel=True functionality is enhanced through the addition of the \ 
functions numba.set_parallel_chunksize and numba.get_parallel_chunksize to \ 
permit a more fine grained scheduling of work defined in a parallel region. \ 
There is also support for adjusting the chunksize via a context manager.

    The ID of a thread is now defined to be predictable and within a known \ 
range, it is available through calling the function numba.get_thread_id.

    The performance of @stencil s has been improved in both serial and parallel \ 
execution.

CUDA enhancements:

    New functionality:

        Self-recursive device functions.

        Vector type support (float4, int2, etc.).

        Shared / local arrays of extension types can now be created.

        Support for linking CUDA C / C++ device functions into Python kernels.

        PTX generation for Compute Capabilities 8.6 and 8.7 - e.g. RTX A series, \ 
GTX 3000 series.

        Comparison operations for float16 types.

    Performance improvements:

        Context queries are no longer made during launch configuration.

        Launch configurations are now LRU cached.

        On-disk caching of CUDA kernels is now supported.

    Documentation: many new examples added.

Docs:

    Numba now has an official “mission statement”.

    There’s now a “version support table” in the documentation to act as \ 
an easy to use, single reference point, for looking up information about Numba \ 
releases and their required/supported dependencies.

General Enhancements:

    Numba imports more quickly in environments with large numbers of packages as \ 
it now uses importlib-metadata for querying other packages.

    Emission of chrome tracing output is now supported for the internal \ 
compilation event handling system.

    This release is tested and known to work when using the Pyston Python \ 
interpreter.
