Release Notes

✨ Highlights

This cycle, the Pixi team focused on squashing bugs.
We especially focused on problems that were annoying and open for some time,
but never quite important to fix right now.

⚠️ Breaking Change

The environment variable overwriting logic is changed.
If you think you haven't read this for the first time, then you are right!
We already attempted to fix the order and other weird aspects of our environment variable handling in the past,
but had to revert it, since it broke too many things.
This time we touched significantly less logic so we hope that the impact will be minimal.

Previously, the variables in your own environment would overwrite the variables set in the Pixi manifest.
This is now reversed, meaning that the variables set in the Pixi manifest will overwrite the variables in your own environment.
Also task environment variables will now be considered even if that environment variable was already defined outside of Pixi.
More info can be found in the documentation.
