- 'Recent changes' show an exclamation mark for adding or modifications of Summary for Flow topic.
- Click on the timestamp - the page that a user is redirected(e.g. http://ca.wikipedia.beta.wmflabs.org/w/index.php?title=Tema:T8h12r03ajc6ftkb&topicsummary_revId=t8uwwe1rdtw17pqw&action=view-topic-summary) does not show 'Mark as patrolled' link.
- Clicking on the "differences from the previous version" link directs to the diff page (http://ca.wikipedia.beta.wmflabs.org/w/index.php?title=Tema:T8h12r03ajc6ftkb&action=compare-postsummary-revisions&topicsummary_newRevision=t8uwwe1rdtw17pqw) shows
All other changes on Flow pages - new topic, topic titles, post revision, board description revision - will have a page with the 'Mark as patrolled' link and also, diff page with the 'Mark as patrolled' link.
