Good morning. This is your Python developer briefing for May 27th, 2026.
Yesterday saw significant activity with 20 merged pull requests and 9 additional commits to the CPython repository.
The headline change comes from Serhiy Storchaka, who merged support for multi-byte encodings in the XML parser. This adds support for encodings including CP932, CP949, Big5, EUC-JP, GB2312, GBK, and Shift_JIS, with partial support for Big5-HKSCS and UTF-8-sig variants.

Mark Shannon merged improvements to the machine stack pointer implementation, making the recursion limit check inline again and consolidating C stack switching logic into the recursive call checker.
