Nine template overrides in the theme, of which four had been superseded by upstream changes and were being loaded in place of maintained files.

A template override is a fork of a file that keeps changing, and the version headers exist precisely so the gap is visible — the status page reports it and nobody reads the status page. Three of the four were replaceable by a filter, and the fourth was genuinely a layout change and was re-forked from the current version with a note about why.
