Deferred changes is a way to mark for review and if necessary delay the visibility of edits identified as suspicious by an automated process until they have been manually reviewed.
What it means for an edit to be deferred
There are two types of 'deferrals', in both cases the edit is queued for review:
- If 'passive', the revision displayed to readers is still the latest revision as usual.
- If 'active', the immediately preceding revision (the same revision that rollback reverts to) is displayed to readers.
If you have been notified, then the deferral was active.
When is an edit deferred
An edit is deferred for review when it matches an abuse filter set to defer, when requested by a bot via the API, or when it is considered highly damaging by ORES. When an edit is deferred, all prior uninterrupted edits by the same user to the page are deferred for review as well.
How to review deferred edits
All deferred edits appear at Special:PendingChanges, which provides the option to list only those actively deferred (or from pending changes-protected pages, if pending changes is enabled), and can be reviewed by users with review permission. When the page has a single author, and the edits can therefore not be deferred, it is listed at Special:UnreviewedPages.
