v0.40.0 (May 1, 2023)
---------------------

This release predominantly upgrades to LLVM 14 and Python 3.11.
Bindings to a large number of passes are added.
The minimum supported Python version is now Python 3.8.

Note: A bug was discovered in LLVM's RuntimeDyldELF on the Aarch64 platform that
can cause segfaults when cross module symbols are linked. It is necessary
for JIT users to build LLVM with the patch added in 
`PR#926 <https://github.com/numba/llvmlite/pull/926>`_.

v0.39.0 (July 25, 2022)
-----------------------

This release predominantly adds new features and improves functionality.

* It's now possible to directly set LLVM ``metadata`` on global variables.
* Functions and global variables now support the specification of a ``section``
  in which they should be placed.
* The attribute ``source_file`` had been added to the ``ModuleRef`` class, it
  returns the module's original file name.
* The FFI library binding to LLVM is now loaded with ``importlib`` to increase
  compatibility with other projects and improve start-up times.
* Linux builds now use the parallel option to ``make`` to speed up building the
  FFI library.
* Preliminary work to expose LLVM's optimization-remarks interface has been
  undertaken. The bindings are exposed and tested, but not yet documented for
  general use (additional work is needed).

Deprecations:

* The ``llvmlite.llvmpy`` module has been deprecated as the functionality it
  provides is available through the ``llvmlite.ir`` module. See the deprecation
  guide in the user documentation for details and recommendations regarding
  replacement.

--------------------------

This release makes llvmlite compatible with Python 3.10. It also adds an
``abiname`` option to the target machine creation interface that mimics the same
in LLVM. Further, a large number of functions are added to the IR API to support
common uses of constant expressions. Finally, a number of bugs were fixed!

v0.37.0 (August 19, 2021)
-------------------------

The biggest new feature in this release is LLVM 11 support for all platforms!
This is important, because the ``aarch64`` platform had been 'stuck' on LLVM 9
for several releases. A special thanks to David Spickett from Linaro for
supplying the relevant patch.

v0.36.0 (March 11, 2021)
------------------------

The main feature in this release is Python 3.9 support. Also, some changes to
the build scripts were included: the llvmdev recipe now supports compilation on
Windows 10 and llvmlite may now be compiled with cmake on POSIX systems.
Additionally, both the timings from the LLVM passes themselves and the time
spent within the LLVM thread-safe access lock are now available for diagnostic
purposes. Lastly, several minor cosmetic changes to the documentation and
project files are included.

v0.35.0 (November 30, 2020)
---------------------------

The main feature in this release is a Numba specific LLVM pass for pruning
reference-count operations. We plan to generalize this custom LLVM pass
once it is proven stable so that it can be configured for other uses.
In addition, this release contains an updated SVML patch that fixes an issue
for AVX512, and a patch that fixes build issues on Linux and BSD.

* PR #617: Fix wheel building.
* PR #618: Fix changelog on master

v0.29.0 (May 29, 2019)
----------------------

This release upgrades to LLVM 8.0 for all supported platforms except PPC64LE.

we have decided to use LLVM 7.1, which is more stable on PPC64LE.
In addition, non-host LLVM targets, AMDGPU, NVPTX, and WebAssembly, are enabled
and they are available in our `llvmlite` builds.

Bugfix release for invalid wheel hash for OSX packages.
No change to source code.


v0.27.0 (Dec 28, 2018)
----------------------

This release updates llvmlite to LLVM 7.  Note that LLVM 7.0.0 contains
a critical bug that is resolved with a patch included in the `llvmdev conda
package recipe`_.  The final release of LLVM 7.0.1 may also resolve the issue.

v0.26.0 (Nov 27, 2018)
----------------------

The primary new features in this release is support for generation of Intel
JIT events, which makes profiling of JIT compiled code in Intel VTune
possible.  This release also contains some minor build improvements for ARMv7,
and some small fixes.

LLVM 7 support was originally slated for this release, but had to be delayed
after some issues arose in testing.  LLVM 6 is still required for llvmlite.

* PR #409: Use native cmake on armv7l
* PR #407: Throttle thread count for llvm build on armv7l.
* PR #403: Add shutdown detection to ObjectRef __del__ method.
* PR #400: conda recipe: add make as build dep
* PR #399: Add get_element_offset to TargetData
* PR #398: Fix gep method call on Constant objects
* PR #395: Fix typo in irbuilder documentation
* PR #394: Enable IntelJIT events for LLVM for VTune support


v0.25.0 (Sep 18, 2018)
----------------------

This release adds support for the FMA instruction, and has some documentation
and build improvements.  Starting with this release, we are including
ARMv8 (AArch64) testig in our CI process.

* PR #391: Fix broken win32 py2.7 build.
* PR #387: protect against empty features in list
* PR #384: Read CMAKE_GENERATOR which conda-build sets
* PR #382: rewrite of install instructions, calling out LLVM build challenges
* PR #380: Add FMA intrinsic support
* PR #379: ARM aarch64 test on jetson tx2
* PR #378: add slack, drop flowdock


v0.24.0 (Jul 6, 2018)
---------------------

This release adds support for Python 3.7 and fixes some build issues. It also
contains an updated SVML patch for the llvmdev package that works around some
vectorization issues. It also adds a selective LLVM 6.0.1 llvmdev build for the
`ppc64le` architecture.

* PR #374: Fix up broken patch selector
* PR #373: Add long description from readme
* PR #371: LLVM 6.0.1 build based on RC and fixes for PPC64LE
* PR #369: Recipe fixes for Conda Build 3
* PR #363: Workaround for incorrect vectorization factor computed for SVML
  functions
* PR #356: fix build on OpenBSD.
* PR #351: Python 3.7 compat: Properly escape repl in re.sub


v0.23.2 (Jun 1, 2018)
---------------------

This is a bug fix release to assist in addressing a critical Numba issue that
can affect users who download llvmlite packages from sources other than PyPI
(pip), Anaconda, or Intel Python: https://github.com/numba/numba/issues/3006

Support for SVML is now detected at compile time and baked into a function that
is exposed by llvmlite. This function can be queried at runtime to find out if
SVML is supported by the LLVM that llvmlite was compiled against, code
generation paths can then be adjusted accordingly.

The following PRs are closed in this release:

* PR #361: Add SVML detection and a function to declare support.


v0.23.1 (May 17, 2018)
----------------------

This is a minor patch release that includes no code changes. It is issued to
fix a couple of problems with the build recipes for llvmdev (on which llvmlite
relies).

The following PRs are closed in this release:

* PR #353: PR Fix llvmdev build recipe.
* PR #348: llvmdev: enhancements to conda recipe


v0.23.0 (Apr 24, 2018)
----------------------

In this release, we upgrade to LLVM 6. Two LLVM patches are added:

  1. A patch to fix LLVM bug (https://bugs.llvm.org/show_bug.cgi?id=37019) that
     causes undefined behavior during CFG printing.
  2. A patch to enable Intel SVML auto-vectorization of transcendentals.

The following PRs are closed in this release:

* PR #343: Fix undefined behavior bug due to Twine usage in LLVM
* PR #340: This moves llvmlite to use LLVM 6.0.0 as its backend.
* PR #339: Add cttz & ctlz
* PR #338: Add 3 Bit Manipulation Intrinsics
* PR #330: Add support for LLVM fence instruction
* PR #326: Enable Intel SVML-enabled auto-vectorization for all the
           transcendentals


v0.22.0 (Feb 15, 2018)
----------------------

In this release, we have changed the locking strategy that protects LLVM from
race conditions.  Before, the llvmlite user (like Numba) was responsible for
this locking.  Now, llvmlite imposes a global thread lock on all calls into
the LLVM API.  This should be significantly less error prone.  Future llvmlite
releases may manually exempt some functions from locking once they are
determined to be thread-safe.

The following PRs are closed in this release:

* PR#318: Ensuring threadsafety in concurrent usage of LLVM C-API
* PR#221: Add all function/return value attributes from LLVM 3.9
* PR#304: Expose support for static constructors/destructors


v0.21.0 (Dec 6, 2017)
---------------------

In this release, we upgrade to LLVM 5.  Our build scripts now use
conda-build 3.  For our prebuilt binaries, GCC 7 toolchain is used
on unix-like systems and the OSX minimum deployment target is 10.9.

The following PRs are closed in this release:

* PR #315: Updates for conda build 3.
* PR #307: Fixes for LLVM5.
* PR #306: Working towards LLVM 5.0 support.
