v2.29.3

Features & Improvements

• Add the --venv option to pdm outdated, like the other commands that read the installed packages. (#3904)

Bug Fixes

• Fix isolated PEP 517 builds skipping packages that are only visible via the host venv's --system-site-packages. (#3895)
• Fix pdm import of Poetry projects dropping optional dependencies whose extras entry is spelled differently, and importing optional dependencies with multiple constraints as required ones. (#3899)
• Keep the plain requirement in pdm export when the same package is also locked with extras under a narrower marker, so it is no longer missing from requirements.txt on the other platforms. (#3900)
• Fix python_version <= "X.Y" markers excluding the patch releases of X.Y, so pdm install skipped such dependencies. (#3902)
• Fix environment variables set by one task of a composite script, via env or env_file, leaking into the tasks that run after it. (#3903)
• Convert flit's comma-separated keywords and obsolete dev-requires into valid PEP 621 fields when importing a flit project. (#3907)
• Import custom Pipfile package categories, such as [docs], as dependency groups instead of dropping them. (#3909)
• Keep editable requirements in [tool.pdm.dev-dependencies] on pdm import, so the written [dependency-groups] table stays valid per PEP 735. (#3910)
• Keep Poetry's develop = true as an editable requirement when importing dependency groups. (#3913)
• Fix pdm import of the project's own Poetry pyproject.toml writing each dependency group to both [tool.pdm.dev-dependencies] and [dependency-groups]. (#3915)
• Import Pipfile packages declared with a file URL, such as {file = "https://..."}, as URL requirements instead of dropping the URL. (#3918)
• Preserve Poetry platform restrictions as environment markers when importing dependencies. (#3920)
• Read an exclude-newer timestamp without a UTC offset as UTC, so pdm lock no longer fails with a TypeError comparing naive and aware datetimes. (#3922)
• Do not write empty dependency groups, such as dev = [] from an empty [dev-packages] table, when importing from another format. (#3925)
• Strip every leading and trailing ., _ and - when pdm init derives the project name from the directory, so a folder like __demo__ no longer produces the invalid name _demo_. (#3927)
• pdm init now writes project.license as a license expression string instead of a {text = ...} table, and no longer rewrites an existing {file = ...} table or license expression into a value the build backend rejects. (#3929)
• Read the inline metadata of a script that starts with a UTF-8 BOM, which pdm run ignored. (#3931)
• Convert a space-separated Poetry version constraint such as >=1.0 <2.0 like the comma-separated form instead of aborting the import. (#3934)
• Resolve relative path entries in a Pipfile against the directory of the Pipfile when importing, instead of the current working directory. (#3935)

Documentation

• Document what to cache and which install command to use when running PDM on CI platforms other than GitHub Actions. (#2472)
