  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)

      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)

• 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.
