July 2024 Releases

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.

📄 What's New in Documentation? 📄

• 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/).
