Released Oct 7, 2025. https://docs.python.org/3/whatsnew/3.14.html
I'm running into some test trouble with supporting Python v3.8 all the
way to v3.14 now, and what seems to be incompatibilities here and there.
This fixes the last build issue to get v3.14 working:
error: the configured Python interpreter version (3.14) is newer than PyO3's maximum supported version (3.13)
= help: please check if an updated version of PyO3 is available. Current version: 0.22.2
= help: set PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to suppress this check and build anyway using the stable ABI
I couldn't find the magic incantation to get the fastapi tests running
with the right dependencies across all versions, so using this ENV var
for now to get it green.
https://github.com/PyO3/pyo3/blob/v0.27.1/CHANGELOG.md#0271---2025-10-21
I'll circle back on it as we will be dropping support to older versions
at some point soon hopefully, so for now I just want to get the build on
Python v3.14 going.

Drop support to Python < 3.10 officially, since they've reached EOL: https://devguide.python.org/versions/ This simplifies our test matrix and makes it easier to support new versions such as Python 3.14 going forward.

Even though I don't think we're using it?
Django v2.2 does not support Python v3.10, according to their release notes: > Django 2.2 supports Python 3.5, 3.6, 3.7, 3.8 (as of 2.2.8), and 3.9 (as of 2.2.17) https://docs.djangoproject.com/en/6.0/releases/2.2/ Plus, the last release was in 2022. https://docs.djangoproject.com/en/6.0/releases/2.2.28/ Django v3.2 seems to be the first version to officially support Python v3.10: https://docs.djangoproject.com/en/6.0/releases/3.2/ I'm keeping our other Django samples which are using v4.2 now, for testing / coverage.
``` % poetry --version Poetry (version 1.8.4) ```
So they don't install dependencies every time. Poetry should be smart enough to run install & use the .venv cache when available. This also changes the main cache to just hash the main `poetry.lock` file, since that's all it needs, and it'd potentially cause a cache miss when only the sample apps might've changed.
