Bug description:
Hello! 👋
(Once the upgrade to Expat 2.7.2 is complete at #138998) please upgrade bundled Expat to 2.7.3 (e.g. for two key bugfixes).
- GitHub release: https://github.com/libexpat/libexpat/releases/tag/R_2_7_3
- Change log: https://github.com/libexpat/libexpat/blob/R_2_7_3/expat/Changes
The CPython issue for previous 2.7.2 was #138998 and the related merged main pull request was #138999, in case you want to have a look. (The Dockerfile from comment #123689 (review) could be of help with raising confidence in a bump pull request when going forward.)
Thanks in advance!
CPython versions tested on:
3.9, 3.10, 3.11, 3.12, 3.13, 3.14, 3.15, CPython main branch
Operating systems tested on:
Linux, macOS, Windows, Other

I'm not adding the 3.9 tag because I don't think we'll backport 2.7.2 to 3.9 considering it's EOL in October.

Makes sense IMO.

Once 2.7.2 is backported, please backport 2.7.3. Thank you for that and sorry for changing the decision at the end.

@StanFromIreland I'm good with you or me doing it. I can get to it some time later today in the evening if it's not been done already by then, as you like 🤝

@StanFromIreland perfect, thanks! 👍
@picnixz could you drop label 3.9 for me? I'll go ahead and close as done…
StanFromIreland commented on Oct 7, 2025
FYI I removed it, but once it's closed we don't need to worry about such labels.

@StanFromIreland thanks, now even future visitors with OCD will feel at home again 😃
