Numba

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

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.

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

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.

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

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.
