What probably matters to youSection of the release
What
Settings pushed by an administrator can now switch off the co-authorship trailers Claude Code adds to commits. When the effective attribution setting resolves to disabled, commit trailers are forced off and the session URL line is suppressed too.
Details
Applies to the projection of managed and policy settings, so a local setting cannot re-enable it.
New helpers detect the case where a settings file supplied by flag or policy was rejected but did contain attribution keys.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
