gh-62259: Add support of multi-byte encodings in the XML parser (GH-149860)
...
Supported encodings: "cp932", "cp949", "cp950", "Big5","EUC-JP",
"GB2312", "GBK", "johab", and "Shift_JIS".
Partially supported encodings (only BMP characters): "Big5-HKSCS",
"EUC_JIS-2004", "EUC_JISX0213", "Shift_JIS-2004", "Shift_JISX0213",
"utf-8-sig" and non-standard aliases like "UTF8" (without hyphen).
The parser now raises ValueError for known unsupported
multi-byte encodings such us "ISO-2022-JP" or "raw-unicode-escape"
instead of failing later, when encounter non-ASCII data.

gh-145235: Make dict watcher API thread-safe for free-threaded builds (gh-145233)
...
In free-threaded builds, concurrent calls to PyDict_AddWatcher, PyDict_ClearWatcher, PyDict_Watch, and PyDict_Unwatch can race on the shared callback array and the per-dict watcher tags. This change adds a mutex to serialize watcher registration and removal, atomic operations for tag updates, and atomic acquire/release synchronization for callback dispatch in _PyDict_SendEvent.
