Contributors

@beeankha

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)

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)

Re-enable all conda_env tests and remove irrelevant tests. (#12813)
Convert all unittest-style tests to pytest-style. (#12819)

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)

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)

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)

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)

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)

Also try UTF16 and UTF32 encodings when replacing the prefix. (#9946)

Bug fixes

conda env update would ask for user input and hang when working with pip installs of git repos and the repo was previously checked out. Tell pip not to ask for user input for that case. (#11818)
Fix for conda update and conda install issues related to channel notices. (#11852)
Signature verification printed None when disabled, changes default metadata_signature_status to an empty string instead. (#11944)
Fix importlib warnings when importing conda.cli.python_api on python=3.10. (#11975)
Several user facing MatchSpec crashes were identified by fuzzing efforts. (#11999)
Apply minimal fixes to deal with these (and similar) crashes. (#12014)
Prevent conda from using /bin/sh + exec trick for its own entry point, which drops $PS1 on some shells (#11885, #11893 via #12043).
