Breaking Changes

• LockedRepository.all_candidates now returns a dict[str, list[Candidate]] instead of dict[str, Candidate]. (#2995)
• post_lock hook now receives a resolution result of type dict[str, list[Candidate]], instead of dict[str, Candidate]. (#2995)

Features & Improvements

• Support reading requirement constraints from pip-style requirement files for "overriding" via --override option. (#2896)

• Add a --non-interactive option for automation scenarios, also interactive prompts will not show up when not running in an interactive terminal. (#2934)

• Add --license and --project-version as CLI options to control and streamline them during pdm init - especially in automated scenarios with --non-interactive (#2978)

• Run pdm sync in "post-rewrite" stage of pre-commit (#2994)

• Project.get_dependencies() now returns a list of Requirement instead of a mapping. The first argument of Project.add_dependencies() now accepts a list of Requirement instead of a mapping. The old usage will be kept working for a short period of time and will be removed in the future. (#2995)

• Support locking for specific target, which is a combination of (python, platform, implementation) triple. Bump lock file version to 4.5.0.

  Example usage: pdm lock --platform=linux --python="==3.8.*" --implementation=cpython. See the docs for more details. (#2995)

• Rename --reuse-env to --recreate for run command, and reverse the behavior. (#2999)

• PDM is now published with optional pinned dependencies using the pdm plugin pdm-build-locked.

  To install pdm with its dependencies pinned to the versions it was tested with, run:

  
      pipx install pdm[locked]
  

  To install optional dependency group copier:

  
      pipx install pdm[locked,copier-locked]
  

  This feature is entirely optional. Installing pdm without the extra will work the same way as before this change. (#3001)

• Added --clean-unselected alias for --only-keep (#3007)

• Group options for update strategy and save strategy. (#3016)

Bug Fixes

• When locking dependencies that references the self project, the referenced groups should also be recorded in the lockfile. (#2976)
• Retry failed installation jobs if they are run sequentially, such as for editable dependencies. (#3005)
• Fix the local path issue when -p is passed to change the project root. (#3009)
• Fix a bug that PDM can't install editable self package with non-isolated build in one go. (#3018)
• Add context when parsing version failed. (#3020)
• Fix a mistake in build env setup that will cause the PATH env var length to grow. (#3022)

Removals and Deprecations

• Remove the deprecation warning of BaseCommand.__init__() method. Now it doesn't take any arguments. (#2995)
• Provider.get_reuse_candidate() method is deprecated in favor of Provider.iter_reuse_candidates(), to return an iterable of reuse candidates. (#2995)
• --no-markers option in pdm export command becomes a no-op and is marked as deprecated, because it doesn't make sense anymore. (#2995)
• ignore_compatibility parameter of Project.get_provider()/Project.get_repository()/Environment.get_finder() is deprecated. Pass in a EnvSpec via env_spec parameter instead. requires_python parameter of pdm.resolver.core.resolve() function is deprecated and has no effect. cross_platform parameter of pdm.cli.actions.resolve_candidates_from_lockfile() function is deprecated and has no effect.
