Hello guys!

Since Python 3.14, it supports partial cookie. Therefore, I am doing this PR: [Fixed #34613 -- Added support for Partitioned cookies by KentaroJay · Pull Request #19603 · django/django · GitHub](https://github.com/django/django/pull/19603)

However I don’t know whether I should drop support for \<= 3.13, or support this new feature only for 3.14, while maintaining support for older versions.

I appreciate it if you could give me any advices! 🙏

If this lands in Django 6.0, it needs to support Python 3.12: [Django 6.0 release notes - UNDER DEVELOPMENT | Django documentation | Django](https://docs.djangoproject.com/en/dev/releases/6.0/#python-compatibility)

As it stands, the PR monkey-patches in support for “partitioned” to `SimpleCookie` on Python \<3.14. I don’t really feel great about Django monkey-patching the standard library, as it may affect other packages using `SimpleCookie`.

I would be fine with merging the feature to support Python 3.14+ only, though. We could add a system check that errors if the user enables any of the new settings on Python \<3.14.

OK, I’ll make sure to keep support Python 3.12  
Thanks for the comment!

I agree with you that monkey-patching the std lib is a great idea. However, as @timgraham told me [there was similar patch in the past](https://github.com/django/django/pull/19603#discussion_r2175530977), I don’t think it would be a blocker if I did it.

I retract my comment about monkey patching, since Tim found precedence for another `SimpleCookie` attribute: [Fixed #34613 -- Added support for Partitioned cookies by KentaroJay · Pull Request #19603 · django/django · GitHub](https://github.com/django/django/pull/19603#discussion_r2175530977)
