Recent changes consist of revisions and log items that are recorded in, and purged from, the recentchanges table, as specified in certain configuration settings. Wiki users can view them at Special:RecentChanges, and clients can access them via the recentchanges part of the API or by connecting to the wiki's RCFeed.
If a particular namespace or log type needs to be hidden in Recent Changes, there are some options:
- Nutze Extension:RecentChangesOption
- Create an extension and use the ChangesListSpecialPageQuery hook
