Release Notes

✨ Highlights

Pixi now supports PEP508 environment markers for PyPI dependencies. Tasks can specify a default_environment, making it easier to run tasks without explicitly selecting an environment. Error messages become more readable with syntax highlighting in error reports.

As usual this release also includes a lot of bug fixes.

⚠️ Breaking

This version introduces a breaking chance in the communication protocol between build backends and pixi. New versions of the build backends that support this protocol have been released but if you pin your build backends to an older version you might encounter an error. Updating the version constraints of your build backend will fix this.
