Release Notes

✨ Highlights

Want a conda/mamba like workflow for Pixi workspaces? This release brings registered workspaces!

You can now register your Pixi workspace and then use its name to refer to it from anywhere on your machine.
For example:

cd path/to/a/pixi/workspace
pixi workspace register
cd
pixi run --workspace workspace-name task-name
pixi shell -w workspace-name
pixi shell-hook -w workspace-name

You can also specify constraints for packages that may be part of your environment without explicitly requiring them (similar to run_constraints for Conda packages):

openssl = ">=3"

Release Notes

✨ Highlights

Pixi now supports PEP508 environment markers for PyPI dependencies. Tasks can specify a default_environment, making it easier to run tasks without explicitly selecting an environment. Error messages become more readable with syntax highlighting in error reports.

As usual this release also includes a lot of bug fixes.

⚠️ Breaking

This version introduces a breaking chance in the communication protocol between build backends and pixi. New versions of the build backends that support this protocol have been released but if you pin your build backends to an older version you might encounter an error. Updating the version constraints of your build backend will fix this.

Added

• default_environment option for specifying the default environment for a task by @prady0t in #5164
• Add set_channels() to WorkspaceContext by @haecker-felix in #5172
• Expose PIXI_VERSION const by @haecker-felix in #5232

• Support PEP508 environment markers by @hameerabbasi in #5241

Fixed

• Hover color on footer links by @ruben-arts in #5189
• pixi lock backend override by @nichmor in #5179

Release Notes

✨ Highlights

Do you need all the build/host/run dependencies of a package?
Now you can add source packages to the [dev] table to get them all at once without installing the package itself.

[dev]
my-package = { path = "src" }

Breaking change for pixi-build preview

This release removes the input hashes from the lockfile for source dependencies to reduce unnecessary lockfile changes. This may cause some lockfiles with source dependencies to become invalid. Rerun pixi lock to fix the lockfile. The changes in this release should significantly reduce lockfile churn when working with source packages going forward.
