The All New Revisions UI and numerous bug fixes!

The revisions system in WordPress has been given a complete overhaul in the new (upcoming) Version 3.6 of  WordPress.  The new version of revisions patches several longstanding bugs and issues with the revisions system and introduces a slick new user interface for viewing and comparing revisions.

The new interface uses a scrollbar and features two modes – a single handle mode where each revision is displayed indicating whats changed in that revision, and a two handled mode where users can compare any two revisions stored in the system and see whats changed between them. Significant effort was put into making the process as fast as possible, and the JavaScript interface means it’s quick to find the revision you are looking for and restore it.

The revisions interface focuses on two primary use cases: undoing mistakes by finding the last correct revisions, and reviewing changes as part of an editorial workflow. To improve these uses, a completely new UI was created, and numerous bugs were fixed.

What’s Fixed in Revisions for WordPress version 3.6

Previous versions of WordPress had several problems with the revisions system that have been corrected in the 3.6 release. The following significant bugs were addressed in this release cycle:

  • Duplicate autosave/revisions clutter the database (because revisions are saved even if nothing has changed) – #9843
  • Extra revision created every time a new post is inserted – by the first time you published a post, there were already two revisions – #24708
  • Restoring post revisions does not update _edit_last – now the revisions system tracks who last restored a post revision – #20982
  • Post Revision history displays the incorrect author – the old system stored a revision before updating a post, yielding bad data that 3.6 corrects. #16215
