Conda maintainer 🐍📦

The July 2024 releases included updates to conda, conda-build, and conda-libmamba-solver! 🎉 All of these have been released to both main and conda-forge channels.

Changes in Conda 24.7.0/24.7.1​

To update conda, run:

conda install -n base conda=24.7.1

✨ What's New? ✨​

  • Add a new reporters setting for configuring output.
  • Report traceback of plugin loading errors with verbosity 2 or higher (-vv or more).
  • Skip checking for .pyc and .pyo files in the conda doctor "missing files" health check.
  • Breaking change conda list --explicit will not print authentication details by default. A new flag --auth has been added so folks can opt-in to this behavior.
  • Print transaction report for @EXPLICIT lockfile installs.
  • Do not require -n/--name or -p/--prefix if conda create is invoked with --dry-run.
  • Add an envvars_force_uppercase setting which defaults to True, uppercasing all environment variables (thereby justifying conda's current behaviour); when envvars_force_uppercase is set to False, conda will only save preserved-case variable names.
  • Alias conda env list command to conda info --envs.
  • Replace calls to logger.warn with logger.warning.

🔧 What Got Fixed? 🔧​

  • Improve treatment of logger levels.
  • Mask authentication details in conda-meta/*.json metadata.
  • Mask Anaconda.org tokens in verbose logs.
  • Fix parsing error when history file only contains a single commented line.
  • Add missing emscripten and wasi entries to the recognized platforms, and wasm32 to the recognized architectures.
  • Fix checksum comparisons in conda.gateways.connection.download.download() to be case insensitive.
  • Fix caching when repodata.json contains \r\n line endings.
  • Fix conda.core.portability.binary_replace not matching chunks that end with \n.
  • (24.7.1) Revert increased restrictions on allowed environment name characters. The previously forbidden characters (^, %, !, =, (, ), ) are allowed again until the impact is assessed.

🌅 What's Marked for Deprecation? 🌅​

  • Mark conda.gateways.logging.initialize_root_logger as pending deprecation.
  • Mark conda.cli.main_env_list.execute as pending deprecation. Use conda.cli.main_info.execute instead.
  • Revert --all deprecation in conda info.
  • Mark conda.exports.iteritems as pending deprecation. Use builtin dict.items() instead.
  • Mark conda.exports.Completer as pending deprecation.
  • Mark conda.exports.InstalledPackages as pending deprecation.
  • Mark conda.exports.KEYS as pending deprecation.

  • Mark conda.exports.verify as pending deprecation.
  • Mark conda.exports.symlink_conda as pending deprecation. Use conda.activate instead.
  • Mark conda.exports._symlink_conda_hlp as pending deprecation. Use conda.activate instead.
  • Mark conda.exports.win_conda_bat_redirect as pending deprecation. Use conda.activate instead.
  • Mark conda.utils.win_path_to_cygwin as pending deprecation. Use conda.common.path.win_path_to_unix instead.
  • Mark conda.utils.cygwin_path_to_win as pending deprecation. Use conda.utils.unix_path_to_win instead.
  • Mark conda.utils.translate_stream as pending deprecation.

📄 What's New in Documentation? 📄​

  • Add type hints and doc strings to conda.core.envs_manager.
  • Add logging overview as deep-dive.
  • Update conda cheatsheet text and add it directly to cheatsheet page.
  • Add updated cheatsheet PDF download to cheatsheet page.
  • Add ssl_verify: truststore to the user guide.
  • Fix the help text of the satisfied-skip-solve flag.
  • Add a section explaining how to correctly raise exceptions from a plugin.
  • Add new article for configuring envs_dirs and pkgs_dirs.

Changes in Conda-Build 24.7.0/24.7.1​

To update conda-build, run:

conda install -n base conda-build=24.7.1

✨ What's New? ✨​

  • Skip generating repodata.json.bz2 for local index; generate repodata.json only; require conda-package-handling >=2.2.0 matching conda.
  • Add new include/exclude sections for glob expressions in multi-output outputs/files.
  • Increase performance by using pickle instead of copy.deepcopy.
  • Report fully rendered recipe to stdout before the build process starts.
  • Validate run_constrained dependencies to prevent faulty specs reaching final repodata.
  • PIP_* env variables are set when building outputs in multi-output recipes.
  • Reduce performance overhead of logging.
  • Do not generate conda error reports for common exceptions.
  • Add CondaBuildUserError exception to replace sys.exit calls.
  • Updated the CI to download the MacOSX 10.15 SDK.

🔧 What Got Fixed? 🔧​

  • Include file path in addition to the content when generating the file hash to avoid unwanted caching during linkage analysis.
  • Error handling when LIEF fails is now consistent with patchelf.
  • Ensure cross-building recipes select the correct noarch package variants.
  • On Linux platforms, prefer the sysroot matching the target_platform when cross-compiling.
  • (24.7.1) Check for WSL existence before calling pathlib.Path.samefile/os.stat.

🌅 What's Marked for Deprecation? 🌅​

  • Mark conda_build.build._construct_metadata_for_test_from_recipe as deprecated. Test built packages instead, not recipes (e.g., conda build --test package instead of conda build --test recipe/).
  • Mark conda_build.build.check_external for deprecation. patchelf is an explicit conda-build dependency on Linux so it will always be installed.

conda install -n base conda-libmamba-solver=24.7.0

✨ What's New? ✨​

  • Document development workflows with devcontainers.
  • Add DevContainer configurations for local development workflows.

🔧 What Got Fixed? 🔧​

  • Allow wildcards in package names for conda remove (e.g. conda remove "python-*").
  • Avoid duplicate channel listing when using channel-pinned specs like channel::package.
  • Fix a performance regression where .solv repodata cache files were not being loaded when available.

  • Pin libmambapy <2 to defend against upcoming API changes.

We ❤️ Our Community​

Altogether, we had 9 (!) new contributors this release cycle; thank you to all of our open source community members for helping making these improvements possible.

If you have ideas or want to help improve any of the conda community projects, we love to see new (and returning) contributors! 😄
