0.42.0 - 2025-03-04

Release Notes

✨ Highlights

This release introduces an improved way of dealing with Virtual Packages.
For example, previously pixi would not allow this configuration on a non-CUDA machine:

[system-requirements]
cuda = "12"

[dependencies]
python = "*"

Now this setup also works on non-CUDA machines, because it only stops if the packages themselves actually depend on CUDA.
This is a first step to make the use of system-requirements/virtual-packages more flexible.
