Add avif mime extension. Optimise skipping watched files which haven't been changed. Block zgrab to save resources. Reduce text and boilerplate. Add route_topic_list_weekviews_start hook. Add topic_list.week_views_filter phrase. Changed footer_powered_by phrase. You will need to run the updater / patcher for this commit.
