Conda maintainer 🐍📦

The April and May 2024 releases included updates to conda and conda-build! 🎉 All of these new releases have been released to both main and conda-forge.

Changes in Conda 24.4.0 and 24.5.0​

To update conda to the latest version, run:

conda install -n base conda=24.5.0

Per conda's release schedule (CEP 8) there is an expected and official release every two months; occasionally however, new features may be added that are significant enough to warrant a separate release in between the bimonthly cadence. The April 2024 release of conda introduces a new enhancement for Windows users. Specifically, the stub executables used for Python entrypoints in packages are now codesigned as a result of pull request #13721.

Amongst other updates, the most recent 24.5.0 version of conda enables MSYS2 packages to utilize upstream installation prefixes, adds support for CEP-15 base_url field in repodata.json, and allows specification of channel URLs using a glob-like wildcard pattern in custom channel settings (e.g., for user with auth handler plugins). See the list below or the release notes for more details.

✨ What's New? ✨​

  • Report which MatchSpec item caused Invalid*Spec exceptions for more informative error messages.
  • Remove setuptools remainings (MANIFEST.in, wheel build dependency) not required since the move to hatch in pull request #12509.
  • Remove and update any imports inside conda that is importing from conda/exports.py.

🔧 What Got Fixed? 🔧​

  • Fix conda notices --json to correctly output JSON.
  • Fix prefix replacement for Windows subdir on Unix.

Changes in Conda-Build 24.5.0​

To update conda-build, run:

conda install -n base conda-build=24.5.0

The May 2024 release of conda-build adds conda_build.metadata._split_line_selector to cache line-selector parsed text, exclusively fetches lfs files for specific git_ref, and enables CodSpeed benchmarks for select tests. See the list below or the release notes for more details.

✨ What's New? ✨​

  • Add conda_build.render.open_recipe context manager to detect the recipe type (file/meta.yaml, directory/recipe, or tarball/package) and properly handling any exit/close behavior.
  • For Windows users, the stub executables used for Python entrypoints in packages are now codesigned.
  • Require conda >=23.7.0.

🔧 What Got Fixed? 🔧​

  • Fix all CLI arguments to properly initialize conda.base.context.context with parsed arguments. Fixes issue with arguments not being processed (e.g., --override-channels was previously ignored).
