ever since the update new posts only have the tags for the first time you read a thread and the forum correctly marks them as read during that same forum session (at least most of the time) ... which is nice

but theres a minor bug when it comes to threads that are more than 3 pages long
if you jump to the last page and there are new posts on the last but one page they are marked as read as soon as you go to that page and you have to manually figure out which posts are the new ones
