Changeset 55289 for trunk/src/wp-includes/comment-template.php

Timestamp:

Message:

Comments: Improve rel attribute usage in comments.

Internal links should be followed and it should be easier to modify other rel attributes on comments. This adds a helper function for determining if a URL is internal and also adds some new filters to make it easy to modify rel attributes in comments.

Props thomasplevy, desrosj, sabernhardt, benish74, samiamnot, galbaras, jorbin.

Fixes #53290, #56444.
