 In [changeset:"48422" 48422]:
 {{{
 #!CommitTicketReference repository="" revision="48422"
 Revisions: optimize performance when post has large number of revisions.

 Improve speed and reduce the memory footprint when loading posts with many
 revisions.

 * Use a direct query in `wp_get_post_autosave` to avoid loading all
 revisions.
 * Query for IDs vs full objects in `register_and_do_post_meta_boxes`.

 Props pdfernhout, johnnyb, miqrogroove, ocean90, senatorman,

 whyisjake.
 Fixes #34560.
