Versioning

uv uses a custom versioning scheme in which the minor version number is bumped for breaking changes, and the patch version number is bumped for bug fixes, enhancements, and other non-breaking changes.

uv does not yet have a stable API; once uv's API is stable (v1.0.0), the versioning scheme will adhere to Semantic Versioning.

uv's changelog can be viewed on GitHub.

Cache versioning

Cache versions are considered internal to uv, and so may be changed in a minor or patch release. See Cache versioning for more.

Lockfile versioning

The uv.lock schema version is considered part of the public API, and so will only be incremented in a minor release as a breaking change. See Lockfile versioning for more.
