v5.0.0 🎄 Merry Christmas - Help fastly and users by default

Changes

This christmans 🎄 release is a bit early bit still full of presents 🎁Since we are changing some of the defaults this can lead to breaking changes, thus the major version increase.

Here are the highlights:

Default to enable-cache: true on GitHub hosted runners

Did you know that that Fastly, the company hosting PyPI, theoretically has to pay $12.5 million per month and so far have served more than 2.41exabytes of data?

This is whythey asked us to turn on caching by default. After weighting the pros and cons we decided to automatically upload the cache to the GitHub Actions cache when running on GitHub hosted runners. You can still disable that withenable-cache: false.

I remember when I first got into actions and didn't understand all the magic. I was baffled that some actions did something behind the scenes to make everything faster. I hope with this change we help a lot of users who are don't want to or are afraid to understand whatenable-cache does.

Add **/requirements*.txt to default cache-dependency-glob

If caching is enabled we automatically searched for auv.lock file and when this changed we knew we had to refresh the cache. A lot of projects don't use this but rather the good oldrequirements.txt. We now automatically search for bothuv.lockandrequirements*.txt (this means alsorequirements-test.txt,requirements-dev.txt, ...) files.You can change this withcache-dependency-glob

Auto activate venv when python-version is set

Some workflows install packages on the fly. This automatically works when using a python version that is already present on the runner. But if uv installs the version, e.g. because it is a free-threaded version or an old one, it is astandalone-build and installing packages "into the system" is not possible.

We now automatically create a new virtual environment withuv venv and activate it for the rest of the workflow ifpython-version is used. This means you can now do

-name:Install uvuses:astral-sh/setup-uv@auto-environmentwith:python-version:3.13t-run:uv pip install -i https://pypi.anaconda.org/scientific-python-nightly-wheels/simple cython
