25.5.0 (2025-05-21)

Enhancements

  • Add the ability to define pre- and post-transaction hooks. (#14754)
  • Adds support for showing and manipulating settings registered via the settings plugin hook to conda config. (#13661 via #14510)
  • Raise conda.exceptions.OfflineError instead of generic RuntimeError when --offline is used for better error handling. (#14664 via #14665)
  • Add context.default_activation_env setting, which allows users to customize which environment should get auto activated on initialization (if context.auto_activate is enabled), as well as conda activate calls without arguments. Defaults to base. (#14666)
  • Provide conda init --condabin, which only adds the $CONDA_PREFIX/condabin directory to the PATH environment variable instead of installing a shell function. (#14703)
  • Add environment_specifiers plugin hooks to allow the creation of plugins to read different file formats and sources. (#14710)
  • Extend PrefixData API with two constructors (from_name(), from_context()), a new property (name), several boolean-returning methods (exists(), is_environment(), is_base()), and a few exception-raising methods (assert_exists(), assert_environment(), assert_writable(), validate_path(), validate_name()). An additional method set_nonadmin() allows to plant the .nonadmin marker on Windows. (#14747 via #14750)
  • Add support for frozen environment markers (CEP 22). (#14746 via #14766)
  • Add a plugin hook for PrefixData loaders and use it to wrap the existing PyPI interoperability features. These are now present in conda.plugins.prefix_data_loaders.pypi. (#14780)
  • Add a --fields flag to conda list that allows to customize the content of the human output format. (#14781)
  • Add debug logs to get visibility into environment spec plugin selection. (#14815)
  • Add conda.models.records.SolvedRecord class. It is a PackageRecord subclass augmented with the requested_spec field originally found in PrefixRecord. (#14821)

Bug fixes

  • Cleanup references to DepsModifier.UPDATE_SPECS. (#14807)
  • Report package variant installation as "REVISED" as opposed to "DOWNGRADED". (#13797 via #14727)
  • Add a validation step to check if the target environment is writable when running the install or update commands. (#12561 via #14668)
  • Fix cache key in PrefixData. It will now consider interoperability. (#14750)
  • Do not cache PrefixData records across successive conda list invocations. (#14750)
  • environment.yaml spec plugin should only handle yaml files (files with .yaml or .yml file extensions). (#14823)
  • Fix conda info rendering to display components in a consistent order. (#14829 via #14831)
