Python 3.10.22, 3.11.17, 3.12.15, 3.13.16 and 3.14.8 Security Releases

Five security releases went out together. They fix tarfile extraction-filter flaws that could write outside the destination directory, unbounded allocation in zipfile, and urllib.request credential scoping by URL scheme.

They also fix ssl and asyncio argument validation, restrict stringprep and the IDNA codec to RFC 3454 codepoints, and update bundled libexpat to 2.8.5. Python 3.10.22 is the final 3.10 release, and 3.13.16 is the last full maintenance release of 3.13.
