0.67.0 - 2026-04-08

Release Notes

✨ Highlights

This release adds the ability to have relative exclude-newer configuration.
Allowing users to specify an acceptable settle time before the package is used in their environments.
This example extensively uses the new exclude-newer configuration options:

[workspace]
# Workspace level exclude newer
exclude-newer = "14d"
# Exact timestamp exclude-newer still works as well:
# exclude-newer = "2025-01-01"

channels = [
    # Channel specific exclude-newer
    { channel = "my-internal-channel", exclude-newer = "0d" },
    "conda-forge",
]
platforms = ["osx-arm64", "linux-64", "linux-aarch64", "osx-64", "win-64"]

[exclude-newer]
# Package specific exclude-newer
bzip2 = "3d"

[dependencies]
python = "*"
snakemake = "*"

[pypi-exclude-newer]
# PyPI package specific exclude-newer
pandas = "1week"

[pypi-dependencies]
pandas = "*"

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):

0.63.0 - 2026-01-14

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
• Add arborium syntax highlighting to miette error reporting by @Hofer-Julian in #5231
• Source records nameless match spec by @baszalmstra in #5103
• Fix installation reading editable from the lock incorrectly by @tdejager in #5249
• Support PEP508 environment markers by @hameerabbasi in #5241

Documentation

• Add section on pinned package conflicts in conda and PyPI integration by @maurosilber in #5217
• Explain the matchspec and source spec by @ruben-arts in #5224
• Improve system requirements documentation clarity by @Hofer-Julian in #5264

Fixed

• Hover color on footer links by @ruben-arts in #5189
• pixi lock backend override by @nichmor in #5179
• Reporter context retrieval by @ruben-arts in #5202
