• 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).
• OpenSSL upgraded from 1.1.1h to 1.1.1i.
• pip upgraded from 20.2.4 to 20.3.3.
• setuptools upgraded from 50.3.2 to 51.1.1.

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.

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.

• 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

• LLVM upgraded to 10.0.1
• musl upgraded to 1.2.1
• LibreSSL upgraded to 3.1.4
• Windows shared distributions now distribute a python3.dll file in addition to the pythonXY.dll file.

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.

20200530

This is a macOS only release that resolves an undefined symbol from libclang-rt inside the tk library.

• Linux build environment upgraded from Debian Wheezy to Jessie. This means the minimum version of glibc required has increased and the oldest glibc version that binaries will run on was released in 2014.
• Linux and macOS distribution now contain a dynamically linked libpython. Distributions contain both a dynamic and static libpython.
• macOS distributions now ship with their own build of tcl/tk 8.6. Previously, they relied on the system's tcl/tk 8.5.
• libncurses is now built with Unicode support.
