Bazel uses a major.minor.patch Semantic Versioning scheme.

  • A major release contains features that are not backward compatible with the previous release. Each major Bazel version is an LTS release.
  • A minor release contains backward-compatible bug fixes and features back-ported from the main branch.
  • A patch release contains critical bug fixes.

Additionally, pre-release versions are indicated by appending a hyphen and a date suffix to the next major version number.

For example, a new release of each type would result in these version numbers:

  • Major: 6.0.0
  • Minor: 6.1.0
  • Patch: 6.1.2
  • Pre-release: 7.0.0-pre.20230502.1

More information is available on the Bazel website.

You should be running one of the supported release numbers listed above in the rightmost column.

You can check the version that you are currently using by running:
bazel --version
