conda-lock 3.0.0

v3.0.0

on Python PyPI

What's Changed

Conda-lock v3 introduces support for mamba / micromamba v2, and includes several important bugfixes.

Only mamba / micromamba versions <2 or >=2.0.7 are supported. (2.0.0–2.0.6 are incompatible.)

The only intended breaking change is to require at least Python 3.9 (previously 3.8). There are several major underlying changes to be aware of:

• The PyPI solver has been updated to Poetry v2.0.1. (#637, #678, #685, #769)
• Lockfiles now support dependencies with multiple categories. (#697)

pixi

Pixi is an innovative new tool for Conda projects that includes lockfile support. While the project-centric philosophy of pixi is different from the environment-centric approach of conda-lock, in many cases it offers a compelling alternative to conda-lock. For a discussion of conda-lock vs pixi, see #615.

Conda-lock v3 includes a new render-lock-spec subcommand capable of exporting conda-lock lock specifications (including ordinary pyproject.toml files) to pixi.toml configurations. See the pixi migration guide for more information.
