x86_64-apple-darwin
distributions are now compiled against macOS SDK 11.1 (downgraded from 11.3). This restores build compatibility with Xcode present in many macOS 10.15 environments.- LLVM/Clang upgraded from 12.0.1 to 13.0.0.
PYTHON.json
files now properly annotate system library and framework linking requirements for the Python core. Previously, only extensions had their link requirements annotated. This missing annotations meant that it was possible for some libraries to not be linked explicitly and for there to be missing libraries/symbols at link time.xcb-proto
upgraded from 1.13 to 1.14.1.- Linux binaries no longer use
pthread_yield()
, ensuring they re-link with glibc 2.34, which deprecated this symbol. (Due to glibc symbol visibility, older distributions will run on glibc 2.34+: they just couldn't be re-linked against 2.34+.)
This release was made a few days after 20211012 and is more tested than that release. It's release notes may be worth reading.
