20250529

Distribution changes

• Fix the implementation of the workaround mentioned in the previous release notes for third-party packages that incorrectly assume the interpreter is statically linking libpython (#623)
• Disable an unsafe optimization that started applying to the statically-linked interpreter which made e.g. subclasses of str misbehave (#622, see also astral-sh/uv#13610)
• Update the "quirks" documentation page (#625)

Upgrades

• xcb-proto 1.14.1 -> 1.17.0 (#627)

Build system changes

• Remove build support for Linux x86 builds (#626). Note that Linux x86 builds have not actually been done since 2023.
• Remove the need for thexcb Docker image as part of #627
• Remove build support for sccache, which was also unused (#629)

20250521

Build changes

• Remove various older X11 packages and expand use of xorgproto (#609)

Distribution changes

• Allow the experimental JIT to be enabled at runtime on Python 3.13 and 3.14 on macOS on aarch64 aka Apple Silicon (#544). Linux was added previously in #538 and #543; our macOS compatibility baseline is too old for x86_64 to enable it at the moment.
• Work around third-party packages that (incorrectly) assume the interpreter is dynamically linking libpython (#621). As with the 20250517 release, we are still statically linking libpython into the interpreter for performance and compatibility, and still shipping a dynamic libpython for compatibility with various tools/workflows that expect it, but we have now tweaked the build to increase the compatibility of this configuration.
