Bazel 6.3.0 is a minor LTS release. It is fully backward compatible with Bazel 6.0 and contains selected changes by the Bazel community and Google engineers.
Highlights
- The new bazel mod command allows users to inspect their external dependency graph in Bzlmod. See documentation for details.
- Full lockfile support has been added to Bzlmod and is now enabled by default. See documentation for details.
General
- Options specified on the pseudo-command
common
in.rc
files are now ignored by commands that do not support them as long as they are valid options for any Bazel command. Previously, commands that did not support all options given forcommon
would fail to run. These previous semantics ofcommon
are now available via the newalways
pseudo-command. (#18609) - Improve error on invalid
-//foo
and-@repo//foo

--top_level_targets_for_symlinks
