Summary of changes in WordPress 3.6

October 16th, 2013 in Upgrade 0 comments

We continue our series of WordPress change summaries with WordPress 3.6. For a brief introduction to these summaries, view the change summary post for WordPress 3.2.

The latest version of WordPress [ for now, WP 3.7 is right around the corner ] introduced a slew of developer focused changes, including a ton of new functions mostly related to media management. The biggest relevant changes are in improvements to Revision Management both on the user side with an improved UI and on the backend with improved handling of revisions. The other big change in WP 3.6 is the addition of an Audio and Video API with a built-in player for both. The API includes access to image and video metadata as well as a slew of new functions and shortcodes.

A few other changes we might want to investigate further include the addition of an in-line login for expired sessions [ make sure it still works with WebLogin ], a filter for revisions allowing sites to set different revision numbers [ might be useful on news/magazine style sites ] and two new shortcode functions that will help determine if a shortcode is in use.


  • Each author now has their own autosave stream, which stores things locally as well as on the server (so much harder to lose something) and there‚Äôs an interface for taking over editing of a post.
  • Revamped Revisions save every change and the new interface allows you to scroll easily through changes to see line-by-line who changed what and when.
  • You can now choose HTML5 markup for things like comment and search forms, and comment lists.
  • Better filters for how revisions work, so you can store a different amount of history for different post types.
  • In-line login following expired sessions
  • Filters for revisions, allowing you to set the number of revisions ad hoc instead of only via a define.
  • Search content for shortcodes with has_shortcode() and adjust shortcode attributes with a new filter.
  • Automatically esc_url() the URL echoed by the_permalink()
  • Allow developers to specify an Accept-Encoding header in WP_Http::accept_encoding()
  • The Revision Management UI saw significant improvement
  • Shortcode attributes can now be filtered via shortcode_atts_$shortcode hook
