• LLVM/Clang updated to 11.1.0.
• preadv() and pwritev() are now disabled on x86_64-apple-darwin builds to restore compatibility with macOS < 11.0.
• Windows static distributions now distribute libffi.lib and the _ctypes extension properly has a dependency on its annotated in PYTHON.json. This should fix issues generating a new library from object files when using metadata from PYTHON.json.
• Windows distributions now have pythoncore annotated as linking against pathcch. This dependency was introduced in Python 3.9 and its previous lack of annotation in PYTHON.json resulted in missing symbols when linking pythoncore.

• i686-unknown-linux-gnu distributions (32-bit x86) are now being produced.
• aarch64-apple-darwin distributions (Apple ARM devices running macOS) are now being produced. These distributions are considered beta quality and there may be some rough edges.
• aarch64-apple-ios and x86_64-apple-ios distributions (iOS and iOS Simulator) are now being produced. These distributions are considered alpha quality and there are known deficiencies. They have not been thoroughly tested.
• Support for building CPython 3.10 alpha releases on Linux has been implemented. These distributions have not been thoroughly tested.
• Linux GNU distributions now link against ld-linux-x86-64.so.2. Please file an issue if this introduces problems.
• binutils updated from version 2.35.1 to 2.36.1.
• LLVM/Clang updated from version 11.0.0 to 11.0.1.
• CPython updated from versions 3.8.7 to 3.8.8 and 3.9.1 to 3.9.2.

• Python 3.9 upgraded from 3.9.0 to 3.9.1
• Releases are now produced from GitHub Actions, which also powers the new CI for this project.
• macOS distributions no longer utilize gettext. This is a regression, as the locale module no longer has certain functionality. However, it was needed to avoid GPL licensing issues and the new behavior matches that of the Linux distributions.
• macOS debug builds now properly reference the libpython dylib.
• Support for build Python 3.7 has been dropped because it made the code unnecessarily complex.
• LibreSSL upgraded from 3.2.2 to 3.2.3 (only affects Linux musl distributions).

This release contains a bug fix to Linux and macOS Python 3.9 distributions where their PYTHON.json files weren't properly advertising object files in the Parser/pegen directory.

20201005

This release contains distributions for CPython 3.9.0.

There have been no changes since the previous release which should affect builds of CPython 3.7 or 3.8, so release artifacts are not provided for these CPython versions.

• Python 3.8 upgraded to 3.8.6
• setuptools upgraded to 50.3.0
• pip upgraded to 20.2.3
• OpenSSL upgraded to 1.1.1h
• Properly annotate libffi dependency for _ctypes extension on Windows
• Experimental support for building CPython 3.9

20200830

This is a Windows, Python 3.8 only release to publish distributions that properly advertise the location of the include directory in distributions. Previously, there was case mismatch between include and `Include.

20200823

This is a macOS only release to correct a regression in the previous release and remove a dependency on libintl.dylib.

20200822

• CPython 3.7 upgraded to 3.7.9
• CPython 3.8 upgraded to 3.8.5
• pip upgraded to 20.2.2
• setuptools upgraded to 49.6.0
• binutils upgraded to 2.35
• GCC upgraded to 10.2.0
• LLVM upgraded to 10.0.1

The macOS distributions for this release have an unwanted dependency on libintl.dylib, which isn't provided by macOS by default and binaries may not run on machines without gettext/libintl installed. Consider using the subsequent release.
