Changeset 30396 for trunk/src/wp-admin/includes/revision.php

Timestamp:

Message:

Introduce two new filters to the post revisions screen:

• process_text_diff_html for contextually filtering a diffed line. Allows for the line to be processed in a different manner to the default htmlspecialchars.
• revision_text_diff_options for filtering the options passed to wp_text_diff() when viewing a post revision.

Fixes #24908
