0.55.0 - 2025-09-15

Release Notes

✨ Highlights

This cycle, the Pixi team focused on squashing bugs.
We especially focused on problems that were annoying and open for some time,
but never quite important to fix right now.

⚠️ Breaking Change

The environment variable overwriting logic is changed.
If you think you haven't read this for the first time, then you are right!
We already attempted to fix the order and other weird aspects of our environment variable handling in the past,
but had to revert it, since it broke too many things.
This time we touched significantly less logic so we hope that the impact will be minimal.

Previously, the variables in your own environment would overwrite the variables set in the Pixi manifest.
This is now reversed, meaning that the variables set in the Pixi manifest will overwrite the variables in your own environment.
Also task environment variables will now be considered even if that environment variable was already defined outside of Pixi.
More info can be found in the documentation.

0.54.0 - 2025-09-01

Release Notes

✨ Highlights

You can now use pixi global tree to visualize the dependency tree of a global environment.

And you can install subsets of packages now works, for both conda and pypi packages:

# Define which packages you want to install and which you want to skip.
pixi install --only packageA --only packageB --skip packageC

# Using this modified environment without updating it again can be done with:
pixi run --as-is my_command
pixi shell --as-is  

Breaking Change

Only for users using preview = ["pixi-build"]:
In #4410 we've made package.name optional. e.g.

[package]
name = "my-package" # This is now optional
version = "0.1.0" # This is now optional

Soon, the backends will be able to automatically get those values from pyproject.toml, Cargo.toml, package.xml etc.
However, this results in the lockfiles not being --locked anymore.
Running pixi lock or pixi update should fix this!

Added

• Add new pixi global tree command by @Carbonhell in #4427
• Add the option for multiple --only flags. by @tdejager in #4477 & #4404

Changed

• Ability to ignore pypi packages during installation by @tdejager in #4456
• Move integration tests to pixi crate by @tdejager in #4472

0.53.0 - 2025-08-19

Release Notes

✨ Highlights

• Big cleanup of the CLI flags, mainly --frozen, --locked, and --no-install.
• Added --as-is to pixi run/shell to run the command without installing the dependencies or touching the lockfile.

0.52.0 - 2025-08-14

Release Notes

✨ Highlights

You can now use pixi global to install source dependencies.

pixi global install --path path/to/my-package my-package

At the moment, you still have to specify the package name, which we will improve on later!

⚠️ Breaking Change

This has be reverted in this release, as there are some issues with it.

0.51.0 - 2025-08-12

Release Notes

✨ Highlights

Pixi now supports --skip on install which means you can skip the installation of a package.
Which can be useful for things like layering Docker images.

Setting no-build-isolation now affects the order in which PyPI packages are installed.
Packages are installed in that order:

• conda packages in one go
• packages with build isolation in one go
• packages without build isolation installed in the order they are added to no-build-isolation

Pixi build got a lot of improvements, including the ability to use build backends from source.
Starting with this release you can get build backends from conda-forge.
We will release stable versions of the build backends on conda-forge, and we maintain a rolling distribution on the pixi-build-backends channel.
The documentation has been updated to reflect this change.

⚠️ Breaking Change

The environment variable overwriting logic is changed.
Previously, the variables in your own environment would overwrite the variables set in the Pixi manifest.
This is now reversed, meaning that the variables set in the Pixi manifest will overwrite the variables in your own environment.
More info can be found in the documentation.
