The Log Deprecated Calls plugin is showing this for the WP-Super-Cache plugin:
Function: get_commentdata()
Called from: wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 406
Replaced with: get_comment()
Just thought it should be said so that it can be removed/altered for a future version. It has no actual impact for the moment, but avoiding deprecated calls is always a good idea.
