0.4.27

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.

0.4.23

Release Notes

This release introduces a revamped system for defining package indexes, as an alternative to the existing pip-style
--index-url and --extra-index-url configuration options.

You can now define named indexes in your pyproject.toml file using the [[tool.uv.index]] table:

[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"

Packages can be pinned to a specific index via tool.uv.sources, to ensure that a given package is installed from the
correct index. For example, to ensure that torch is always installed from the pytorch index:

[tool.uv.sources]
torch = { index = "pytorch" }

[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"

Indexes can also be marked as explicit = true to prevent packages from being installed from that index
unless explicitly pinned. For example, to ensure that torch is installed from the pytorch index, but all other
packages are installed from the default index:

[tool.uv.sources]
torch = { index = "pytorch" }

[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cpu"
explicit = true

To define an additional index outside a pyproject.toml file, use the --index command-line argument
(or the UV_INDEX environment variable); to replace the default index (PyPI), use the --default-index command-line
argument (or UV_DEFAULT_INDEX).

These changes are entirely backwards-compatible with the deprecated --index-url and --extra-index-url options,
which continue to work as before.

See the Index documentation for more.
