0.49.0 - 2025-06-30

Release Notes

✨ Highlights

This release enables pixi to pick up extensions that are installed as pixi-.
This is similar to cargo, git and other tools.
This means that you can now install extensions like this:

pixi global install pixi-pack
pixi pack

It also allows you to use pixi exec more easily:

pixi exec --with numpy python -c "import numpy; print(numpy.__version__)"
# Previous command is equivalent to:
pixi exec --spec numpy --spec python python -c "import numpy; print(numpy.__version__)"
