Release Notes

✨ Highlights

This release brings a lot of exciting features.

Workspace dependencies

We now allow to define workspace dependencies that allows to set package matchspecs that then can be inherited by package dependencies. This is how it looks like:

[workspace.dependencies]
numpy = "1.*"
boltons = { version = ">=24", channel = "conda-forge" }

# Build packages
[package.build]
backend = { name = "foo-build", workspace = true }

[package.host-dependencies]
cmake = { workspace = true }

[package.target.linux-64.run-dependencies]
numpy = { workspace = true }

• Parallel pixi global update, which bring significant speedups if you have many installations
