Security content in this release

• CVE-2022-40674: bundled libexpat was upgraded from 2.4.7 to 2.4.9 which fixes a heap use-after-free vulnerability in function doContent
• gh-97616: a fix for a possible buffer overflow in list *= int

No installers

According to the release calendar specified in PEP 569, Python 3.8 is now in the "security fixes only" stage of its life cycle: 3.8 branch only accepts security fixes and releases of those are made irregularly in source-only form until October 2024. Python 3.8 isn't receiving regular bug fixes anymore, and binary installers are no longer provided for it. Python 3.8.10 was the last full bugfix release of Python 3.8 with binary installers.
