0.40.1 - 2025-01-14

Release Notes

✨ Highlights

We've reverted the breaking change of the depends_on field from 0.40.0, replacing it with a warning.

This release also brings a performance boost to our Windows and Linux-musl builds by using faster allocators.
On the (holoviews) project, we measured a significant speedup:

# Linux musl
Summary
  pixi-0.40.1 list --no-install ran
   12.65 ± 0.46 times faster than pixi-0.40.0 list --no-install

# Windows
  pixi-0.40.1 list --no-install ran
    1.66 ± 0.07 times faster than pixi-0.40.0 list --no-install
    1.67 ± 0.09 times faster than pixi-0.39.5 list --no-install
    2.10 ± 0.09 times faster than pixi-0.39.4 list --no-install

Fixed

• Pyproject entry-points by @atmorling in #2886
• Print warning when pixi manifest is not parsed in pixi search by @pavelzw in #2889
• Add deprecation notice for depends_on by @baszalmstra in #2891

Performance

• Use faster allocators by @baszalmstra in #2874

Refactor

• Add online_tests feature to control Internet use by @mgorny in #2881
• Simplify repodata_gateway function by @olivier-lacroix in #1793
• Spawn main entrypoint in box by @baszalmstra in #2892

0.40.0 - 2025-01-10

Release Notes

✨ Highlights

Manifest file parsing has been significantly improved.
Errors will now be clearer and more helpful, for example:

         × Expected one of 'first-index', 'unsafe-first-match', 'unsafe-best-match'
          ╭─[pixi.toml:2:27]
        1 │
        2 │         index-strategy = "UnsafeFirstMatch"
          ·                           ────────────────
        3 │
          ╰────
         help: Did you mean 'unsafe-first-match'?

Breaking Change Alert:

The depends_on field has been renamed to depends-on for better consistency.
Using the old format without a dash (depends_on) will now result in an error.
The new errors should help you find the location:

Error:
  × field 'depends_on' is deprecated, 'depends-on' has replaced it
    ╭─[pixi.toml:22:51]
 21 │ install = "cargo install --path . --locked"
 22 │ install-as = { cmd = "python scripts/install.py", depends_on = [
    ·                                                   ─────┬────
    ·                                                        ╰── replace this with 'depends-on'
 23 │   "build-release",
    ╰────

0.39.5 - 2025-01-06

Release Notes

✨ Highlights

By updating resolvo to the latest version we now significantly lower the RAM usage during the solve process. 🚀
As this improvement removes a huge set of data from the solve step it also speeds it up even more, especially for hard to solve environments.

Some numbers from the resolvo PR, based on the resolve test dataset:

- Average Solve Time: 'pixi v0.39.5' was 1.68 times faster than 'pixi v0.39.4'
- Median Solve Time: 'pixi v0.39.5' was 1.33 times faster than 'pixi v0.39.4'
- 25th Percentile: 'pixi v0.39.5' was 1.22 times faster than 'pixi v0.39.4'
- 75th Percentile: 'pixi v0.39.5' was 2.28 times faster than 'pixi v0.39.4'
