Release Notes
This release includes support for the [dependency-groups] table as recently standardized in PEP 735. The table allows for declaration of optional dependency groups that are not published as part of the package metadata, unlike [project.optional-dependencies]. There are new --group, --only-group, and --no-group options throughout the uv interface.Previously, uv used a single tool.uv.dev-dependencies list for declaration of development dependencies. Now, uv supports declaring development dependencies in a standardized format and allows splitting development dependencies into multiple groups.For compatibility, and to simplify usage for people that do not need multiple groups, uv special-cases the group named dev. The dev group is equivalent to tool.uv.dev-dependencies. The contents of tool.uv.dev-dependencies will merged into the dev group in uv's resolver. The --dev, --only-dev, and --no-dev flags remain as aliases for the corresponding --group options. Support for tool.uv.dev-dependencies remains in this release, but will display warnings in a future release.uv syncs the dev group by default — this matches the exististing behavior for tool.uv.dev-dependencies. The default groups can be changed with the tool.uv.default-groups setting.Thank you to Stephen Rosen who authored PEP 735.Enhancements
