v0.39.0 - 2024-12-02

✨ Highlights

• We now have a new concurrency configuration in the pixi.toml file.
  This allows you to set the number of concurrent solves or downloads that can be run at the same time.
• We changed the way pixi searches for a pixi manifest. Where it was previously first considering the activated pixi shell, it will now search first in the current directory and its parent directories. more info
• The lockfile format is changed to make it slightly smaller and support source dependencies.

Pixi build

We've merged in the main pixi build feature branch. This is a big change but shouldn't have affected any of the current functionality.
If you notice any issues, please let us know.

It can be turned on by preview = "pixi-build" in your pixi.toml file. It's under heavy development so expect breaking changes in that feature for now.

• Preview of pixi build and workspaces by @tdejager in #2250
• Build recipe yaml directly by @wolfv in #2568

New Contributors

• @seowalex made their first contribution in #2580
