Features & Improvements

• Defer command action and Python installer imports until their corresponding runtime paths execute. (#​3673)
• Add {run_cwd} placeholder for scripts to reference the original working directory. (#​3734)
• Add opt-in canonical lock input freshness via tool.pdm.resolution.lock_inputs while retaining sticky lockfile behavior and legacy hash fallback for existing lock files. (#​3821)
• Integrate argcomplete for simplified command-line completion scripts. (#​3823)

Bug Fixes

• Keep workspace members in their explicitly declared dependency groups instead of adding them to default in the lockfile. (#​3816)
• Keep the cached parsed version intact when stripping the local segment in comparable_version(). (#​3817)
• Make use_uv support adding local files. (#​3822)
• Add a Poetry optional dependency to every extra that lists it when importing, instead of only the first one. (#​3831)
• Do not write null values into the generated pyproject.toml when importing a flit project that omits author-email/maintainer-email or sets only one of include and exclude in [tool.flit.sdist]. (#​3832)

Miscellany

• Add Python 3.15 preview version to the CI matrix. (#​3827)
