Update
uv versionto display and update project versions (#12349)Previously,
uv versiondisplayed uv's version. Now,uv versionwill display or update the project's version. This interface was heavily requested and, after much consideration, we decided that transitioning the top-level command was the best option.Here's a brief example:
If used outside of a project, uv will fallback to showing its own version still:
As described in the warning,
--previewcan be used to error instead:The previous functionality of
uv versionwas moved touv self version.Avoid fallback to subsequent indexes on authentication failure (#12805)
When using the
first-indexstrategy (the default), uv will stop searching indexes for a package once it is found on a single index. Previously, uv considered a package as "missing" from an index during authentication failures, such as an HTTP 401 or HTTP 403 (normally, missing packages are represented by an HTTP 404). This behavior was motivated by unusual responses from some package indexes, but reduces the safety of uv's index strategy when authentication fails. Now, uv will consider an authentication failure as a stop-point when searching for a package across indexes. Theindex.ignore-error-codesoption can be used to recover the existing behavior, e.g.:Since PyTorch's indexes always return a HTTP 403 for missing packages, uv special-cases indexes on the
pytorch.orgdomain to ignore that error code by default.Require the command in
uvx <name>to be available in the Python environment (#11603)Previously,
uvxwould attempt to execute a command even if it was not provided by a Python package. For example, if we presumefoois an empty Python package which provides no command,uvx foowould invoke thefoocommand on thePATH(if present). Now, uv will error early if thefooexecutable is not provided by the requested Python package. This check is not enforced when--fromis used, so patterns likeuvx --from foo bash -c "..."are still valid. uv also still allowsuvx foowhere thefooexecutable is provided by a dependency offooinstead offooitself, as this is fairly common for packages which depend on a dedicated package for their command-line interface.Use index URL instead of package URL for keyring credential lookups (#12651)
When determining credentials for querying a package URL, uv previously sent the full URL to the
keyringcommand. However, some keyring plugins expect to receive the index URL (which is usually a parent of the package URL). Now, uv requests credentials for the index URL instead. This behavior matchespip.Remove
--versionfrom subcommands (#13108)Previously, uv allowed the
--versionflag on arbitrary subcommands, e.g.,uv run --version. However, the--versionflag is useful for other operations since uv is a package manager. Consequently, we've removed the--versionflag from subcommands — it is only available asuv --version.Omit Python 3.7 downloads from managed versions (#13022)
Python 3.7 is EOL and not formally supported by uv; however, Python 3.7 was previously available for download on a subset of platforms.
Reject non-PEP 751 TOML files in install, compile, and export commands (#13120, #13119)
Previously, uv treated arbitrary
.tomlfiles passed to commands (e.g.,uv pip install -r foo.tomloruv pip compile -o foo.toml) asrequirements.txt-formatted files. Now, uv will error instead. If using PEP 751 lockfiles, use the standardized format for custom names instead, e.g.,pylock.foo.toml.Ignore arbitrary Python requests in version files (#12909)
uv allows arbitrary strings to be used for Python version requests, in which they are treated as an executable name to search for in the
PATH. However, using this form of request in.python-versionfiles is non-standard and conflicts withpyenv-virtualenvwhich writes environment names to.python-versionfiles. In this release, uv will now ignore requests that are arbitrary strings when found in.python-versionfiles.Error on unknown dependency object specifiers (12811)
The
[dependency-groups]entries can include "object specifiers", e.g.set-phasers-to = ...in:However, the only current spec-compliant object specifier is
include-group. Previously, uv would ignore unknown object specifiers. Now, uv will error.Make
--frozenand--no-sourcesconflicting options (#12671)Using
--no-sourcesalways requires a new resolution and--frozenwill always fail when used with it. Now, this conflict is encoded in the CLI options for clarity.Treat empty
UV_PYTHON_INSTALL_DIRandUV_TOOL_DIRas unset (#12907, #12905)Previously, these variables were treated as set to the current working directory when set to an empty string. Now, uv will ignore these variables when empty. This matches uv's behavior for other environment variables which configure directories.
