 **Breaking changes**:
 
-- ...
+- [Repository Links] now work for [multi-language] sites ([#1744]).
+
+  For any given page, repository links are now computed from a page's _resolved_
+  `File` path, as resolved _through_ mount points, if any. That is, the path
+  used is the one that refers to the file's actual location on disk, not it's
+  logical path in Hugo's [union file system].
+
+  This is a breaking change pages of sites that use mounts and
+  [path_base_for_github_subdir]. Projects will need to adjust the value of
+  [path_base_for_github_subdir] to be relative to the file's physical location.
