-- Project lookups now accept either ID or name on `GET /org/projects/{id}`, so you can resolve a named project without paging through the project list.
-- Added `GET /extensions/{id_or_name}/metadata` to return extension metadata by ID or name without downloading the archive.
-
-## Documentation updates
-
-- Updated the [Projects](/info/projects) page and [Extensions](/browsers/extensions) guide with the new direct lookup behavior.
