My website uses a number of custom post types, as well as "posts" and "pages".
I've noticed that revision history appears automatically for "posts" and "pages", while when custom post type entries have no revision history at all. I plan to eventually enable revisions for all the custom fields for my individual custom post types, but can't get working on that until revisions are at least recorded - even when I change post_title or the_excerpt, there is no revision history.
Has anyone had any similar issue with custom post types?
Should any php ninjas stumble upon this, here is my functions.php file where the custom post types are defined - what I assume to be the probable culprit: http://pastebin.com/Bmn6p4Md
Thanks in advance for any help.
