 In [changeset:"30091"]:

 Introduce some actions and filters which aid plugins in revisioning post
 meta.

  * `wp_save_post_revision_post_has_changed` filter which can be used to
 determine if a post has been changed, and therefore if a revision should
 be created for a post.
  * `wp_get_revision_ui_diff` filter which can be used to filter the fields
 displayed in the post revision diff UI.
  * `wp_creating_autosave` action which is fired just before an autosave is
 created.

 See #20564.
 Props mattheu, adamsilverstein.
