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.

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.

With cache	https://prefix.dev/conda-forge	69.3	1.00
Without	https://prefix.dev/conda-forge	389.5	5.62

v0.33.0

✨ Highlights

This is the first release with the new pixi global implementation. It's a full reimplementation of pixi global where it now uses a manifest file just like pixi projects. This way you can declare your environments and save them to a VCS.

It also brings features like, adding dependencies to a global environment, and exposing multiple binaries from the same environment that are not part of the main installed packages.

Test it out with:

# Normal feature
pixi global install ipython

# New features
pixi global install \
    --environment science \           # Defined the environment name
    --expose scipython=ipython \      # Expose binaries under custom names
    ipython scipy                     # Define multiple dependencies for one environment

This should result in a manifest in $HOME/.pixi/manifests/pixi-global.toml:

version = 1

[envs.ipython]
channels = ["conda-forge"]
dependencies = { ipython = "*" }
exposed = { ipython = "ipython", ipython3 = "ipython3" }

[envs.science]
channels = ["conda-forge"]
dependencies = { ipython = "*", scipy = "*" }
exposed = { scipython = "ipython" }

Breaking changes

This release breaks some CLI commands for pixi global

Before v0.33	In v0.33.0	Comment
pixi global upgrade package	pixi global update environment_name	updates the environment to the highest versions possible within the spec from the manifest
pixi global upgrade-all	pixi global update	Updates all environments to the highest possible version within the spec from the manifest
pixi global remove	pixi global uninstall	remove has become the opposite of add and uninstall of install, thus remove only removes packages from an environment not the environment itself

v0.32.2 - 2024-10-16

✨ Highlights

• pixi self-update will only work on the binaries from the GitHub releases, avoiding accidentally breaking the installation.
• We now support gcs:// conda registries.

Changed

Documentation

• Small fixes in tutorials/python.md by @carschandler in #2252

v0.32.1 - 2024-10-08

Fixes

• Bump Rust version to 1.81 by @wolfv in #2227

Documentation

• Pixi-pack, docker, devcontainer by @pavelzw in #2220

Note

The task cache from inputs and outputs is most likely going to be invalidated, and thus will be rebuild. This had to do with a difference in the hash of a std::Path in this version of Rust.
