Changeset 53842 for trunk/src/wp-admin/includes/meta-boxes.php

Timestamp:

Message:

Revisions: Use wp_get_latest_revision_id_and_total_count() where appropriate.

The function executes an optimized query to get the last revision ID and total count. It was originally introduced for WP_REST_Posts_Controller::prepare_links(), and is now used in a few more places in core:

• register_and_do_post_meta_boxes()
• wp_get_post_revisions_url()
• wp_update_custom_css_post()

Follow-up to [53759], [53769], [53778], [53779], [53841].

Props peterwilsoncc, mukesh27, SergeyBiryukov.
Fixes #56279.
