23.7.0

Enhancements

• Add conda.deprecations.DeprecationHandler.action helper to deprecate argparse.Actions. (#12493)
• Add support for the FreeBSD operating system and register freebsd-64 as a known subdirectory for FreeBSD on x86-64. (#12647)
• Do not mock $CONDA_PREFIX when --name or --prefix is provided. (#12696)
• Add support for sha256 filters in the MatchSpec syntax (e.g. *[sha256=f453db4ffe2271ec492a2913af4e61d4a6c118201f07de757df0eff769b65d2e]). (#12654 via #12707)
• Add a new health check to conda doctor detecting altered packages in an environment by comparing expected and computed sha256 checksums. (#12757)
• Add new pre_commands and post_commands plugin hooks allowing plugins to run code before and after conda subcommands. (#12712, #12758, #12864)
• Stop using distutils directly in favor of the vendored version in setuptools 60 and later or standard library equivalents. (#11136)
• Add a CITATION.cff file to the root of the repository to make it easier for users to cite conda. (#12781)
• Add optional CondaSubcommand.configure_parser allowing third-party plugins to hook into conda's argument parser. (#12814)
• Only display third-party subcommands in conda --help and not for every other subcommand. (#12814, #12740)
• Add a new config option, no_plugins, a --no-plugins command line flag, and a CONDA_NO_PLUGINS environment variable that disables external plugins for built-in conda commands. (#12748)
• Register plugins using their canonical/fully-qualified name instead of the easily spoofable entry point name. (#12869)
• De-duplicate plugin and legacy subcommands in conda --help. (#12893)
• Implement a 2-phase parser to better handle plugin disabling (via --no-plugins). (#12910)
• Refactor subcommand parsing to use a greedy parser since argparse.REMAINDER has known issues. (#12910)

Bug fixes

• Use requests.exceptions.JSONDecodeError for ensuring compatibility with different json implementations used by requests. This fixes a bug that caused only the first of multiple given source URLs to be tried. This also raises the minimum required requests version to 2.27.0. (#12683)
• Don't export __osx virtual package when CONDA_OVERRIDE_OSX="". (#12715)
• Fix erroneous conda deactivate behavior of unsetting preexisting environment variables that are identical to those set during conda activate. (#12769)
• Correct third-party subcommands to receive remaining arguments instead of a blanket sys.argv[2:] which broke conda_cli testing. (#12814, #12910)

Deprecations

• Mark conda.base.context.context.root_dir as pending deprecation. Use conda.base.context.context.root_prefix instead. (#12701)
• Mark conda.plugins.subcommands.doctor.cli.get_prefix as pending deprecation. Use conda.base.context.context.target_prefix instead. (#12725)

• Update tests/test_activate.py to test the new behavior. (#12769)
• Re-enable all conda_env tests and remove irrelevant tests. (#12813)
• Convert all unittest-style tests to pytest-style. (#12819)

• Avoid TypeError when non-string types are written to the index cache metadata. (#12562)
• conda.core.package_cache_data.UrlsData.get_url no longer fails when package_path has .conda extension. (#12516)
• Stop pre-converting paths to Unix style on Windows in conda.sh, so that they are prefix replaceable upon installation, which got broken by #12509. It also relies on cygpath at runtime, which all msys2/cygwin bash versions on Windows should have available. (#12627)

Full Changelog: 23.3.0...23.3.1

23.3.0

Enhancements

• Allow the use of environment variables for channel urls in environment.yaml. (#10018)
• Improved error message for conda env create if the environment file is missing. (#11883)
• Stop using toolz.dicttoolz.merge and toolz.dicttoolz.merge_with. (#12039)
• Add support for incremental repodata.json updates with --experimental=jlap on the command line or experimental: ["jlap"] in .condarc (#12090). Note: switching between "use jlap" and "don't use jlap" invalidates the cache.
• Added a new conda.deprecations module for easier & standardized deprecation. Includes decorators to mark functions, modules, classes, and arguments for deprecation and functions to mark modules, constants, and topics for deprecation. (#12125)
• Adds a new channel_settings configuration parameter that will be used to override arbitrary settings on per-channel basis. (#12239)
• Improve speed of repodata.json parsing by deferring creation of individual PackageRecord objects. (#8500)
• Refactor subcommand argument parsing to make it easier to understand. This calls the plugin before invoking the default argument parsing. (#12285)
• Handle I/O errors raised while retrieving channel notices. (#12312)
• Add support for the 64-bit RISC-V architecture on Linux. (#12319)
• Update vendored version of py-cpuinfo to 0.9.0. (#12319)
• Improved code coverage. (#12346, #12457, #12469)
• Add a note about use_only_tar_bz2 being enabled on PackagesNotFoundError exceptions. (#12353)
• Added to conda CLI help that conda remove -n <myenv> --all can be used to delete environments. (#12378)
• Handle Python import errors gracefully when loading conda plugins from entrypoints. (#12460)

Bug fixes

• Fixed errors when renaming without an active environment. (#11915)
• Prevent double solve attempt if PackagesNotFoundError is raised. (#12201)
• Virtual packages follow context.subdir instead of platform.system() to enable cross-platform installations. (#12219)
• Don't export __glibc virtual package when CONDA_OVERRIDE_GLIBC="". (#12267)
• Fix arg_parse pass-through for --version and --help in conda.xsh. (#12344)
• Filter out None path values from pwd.getpwall() on Unix systems, for users without home directories, when running as root. (#12063)
• Catch ChunkedEncodingError exceptions to prevent network error tracebacks hitting the output. (#12196 via #12487)
• Fix race conditions in mkdir_p_sudo_safe. (#12490)

Deprecations

• Drop toolz.itertoolz.unique in favor of custom conda.common.iterators.unique implementation. (#12252)
• Stop using OrderedDict/odict since dict preserves insert order since Python 3.7. (#12254)
• Mark conda._vendor.boltons for deprecation in 23.9.0. (#12272, #12482)
• Mark conda_exe in context.py and a topic in print_package_info cli/main_info.py for official deprecation. (#12398)
• Remove unused chain, methodcaller, mkdtemp, StringIO imports in conda.common.compat; apply other fixes from ruff --fix . in the test suite. (#12294)
• Remove unused optimization for searching packages based on *[track_features=<feature name>]. (#12314)
• Remove Notebook spec support from conda env; this was deprecated already and scheduled to be remove in version 4.5. (#12307)
• Mark conda_exe in context.py and a topic in print_package_info cli/main_info.py for official deprecation. (#12276)
• Marking conda.utils.hashsum_file as pending deprecation. Use conda.gateways.disk.read.compute_sum instead. (#12414)
• Marking conda.utils.md5_file as pending deprecation. Use conda.gateways.disk.read.compute_sum(path, "md5") instead. (#12414)
• Marking conda.gateways.disk.read.compute_md5sum as pending deprecation. Use conda.gateways.disk.read.compute_sum(path, "md5") instead. (#12414)
• Marking conda.gateways.disk.read.compute_sha256sum as pending deprecation. Use conda.gateways.disk.read.compute_sum(path, "sha256") instead. (#12414)
• Drop Python 3.7 support. (#12436)

Docs

• Added docs for conda.deprecations. (#12452)
• Updated some instances of "Anaconda Cloud" to be "Anaconda.org". (#12238)
• Added documentation on the specifications for conda search and conda install. (#12304)
• Mark conda.utils.safe_open for deprecation. Use builtin open instead. (#12415)

Other

• Update <cache key>.json.state repodata.json cache format; check mtime against cached repodata.json. (#12090)
• Skip redundant tar --no-same-owner when running as root on Linux, since newer conda-package-handling avoids setting ownership from the archive. (#12231)
• Add additional extensions to conda.common.path for future use. (#12261)
• Pass --cov in test runner scripts but not in setup.cfg defaults, for easier debugging. (#12268)
• Constrain conda-build to at least >=3.18.3, released 2019-06-20. (#12309)
• Improve start.bat Windows development script. (#12311)
• Provide conda-forge-based Docker images and fix the bundled minio binary. (#12335)
• Add support for conda-forge-based CI runtimes. On Linux (all architectures), unit & integration tests will use Python 3.10. On Windows, Python 3.8. On macOS, only the unit tests are run with conda-forge (instead of defaults!), using Python 3.9. (#12350, #12447 via #12448)
• Fix testing data issue where the subdir entry in some files was mismatched. (#12389)
• Initialize conda after installing test requirements during CI. (#12446)
• Speedup pre-commit by a factor of 15 by removing ignored hooks (pylint/bandit). This locally reduces the pre-commit runtime from ~43sec to 2.9sec and thus makes it possible to run pre-commit in a loop during development to constantly provide feedback and style the code. (#12466)
