Django 5.2 will be the first version to support Python 3.14

---

tests/test_cache_options.py fails on Python 3.14 because of:

• ImportError when attempting to test with Python 3.14 python-lz4/python-lz4#302
• Correct the import of _compression for Python 3.14 python-lz4/python-lz4#303

What's new in Python 3.14: PEP 784: Adding Zstandard to the standard library

Hi!

thank you! looks good to me

hi
please reset this last commit
we keep a linear history, so a rebase is the way to handle it
tho if it's a problem, i can do it myself 👍

I have rebased to a single commit, but this pull request is in draft mode because it has failing tests caused by:

• ImportError when attempting to test with Python 3.14 python-lz4/python-lz4#302

[amirreza8002]

yup
thank you 🙌
I'll merge as soon as they fix their end

[cclauss]

The GitHub UI provides Squash and merge to make it easy to keep history linear.

[amirreza8002]

yup
but usually i want all commits to be available, so squashing is not my go to option, rebase is the way

hi 👋
seems like 3.14t is not a valid classifier
did you mean Programming Language :: Python :: Free Threading?

[cclauss]

Let's back off on 3.14t until after 3.14 lands.

[amirreza8002]

this looks good to me
thakn you 🙌
if you don't have anything to add, i'll merge it

[cclauss]

Go for it. Thx.
