Change Tracking

Every save creates a revision — including the first save of a new article. You can review how an article evolved, compare versions, and recover older content. Revisions are retained indefinitely.

Viewing Revision History

Open an article and scroll to the bottom.
Select the Revisions tab (next to Related Articles and Notes).

Revisions are listed newest first, with timestamp and author.

Comparing Revisions

Click Compare with current on any revision to see a word-level diff:

Added text in green
Removed text in red with strikethrough
Unchanged text as normal

Théoden rides for Helm's Deep with [removed]one thousand[/removed][added]six thousand[/added] riders.

Diffs are computed with Myers' algorithm at word granularity; long changes stay readable and a side-by-side comparison is available.

Visibility in Revisions

Revision history respects visibility rules:

The Ranger introduces himself only as Strider.

<!-- start: secret; party -->
His true name is Aragorn, heir of Isildur.
<!-- end: secret -->

A user outside party sees only the public sentence in every revision, and the diff shows no change there. A party member sees the secret block highlighted as added.
