… block The 26.8 backport carries the entry in the 26.7 block, which is what `compatibility` needs: a version before 26.7 restores the earlier acceptance of a `Variant`/`Dynamic` key written as `GROUP BY ALL`. The `settings_changes_history` style check additionally requires every setting the change touches to be recorded under the current version block, so add the no-op record (previous value equal to the new one) under 26.8 as well, mirroring what master carries under 26.9.
