It is my pleasure to announce that v0.7.0 is released and is available through PyPI
as a sdist and also as wheels.

This release drops Python 2 support and Python < 3.6 support and brings in support for PyPy and
other architectures.

Binary wheels are available for 6 python versions (3.6, 3.7, 3.8, 3.9, PyPy3.6, PyPy3.7) for 6 platforms
(linux-x86_64, linux-aarch64, linux-ppc64le, macosx-x86_64, macosx-arm64, win-x86_64).
Not all combinations are available though. All of them have been compiled with GMP/MPIR, MPFR,
MPC, FLINT and LLVM. Manylinux1 support is retained, but wheels have been dropped.

As the linux-aarch64, linux-ppc64le, macosx-arm64 wheels are cross compiled, they are not tested
and we'd like to hear if they work for you.

People who contributed to the release:
* Isuru Fernando  
* Jialin Ma  
* Rikard Nordgren  
* Rohit Goswami

Thanks to everybody who contributed with code, bug reports and reviews. Release notes are
at the end of the email.
