The new post and new thread indiciation seems to have degraded a bit after the recent downtime/upgrade/bugfix.

Unchanged:
The main forum list shows new which forums have new threads.
Clicking on a forum shows which threads have new posts.

Changed:
Clicking on a thread with new posts doesn't show the light blue/gray (default theme) post heading to indicate they are new.

In a forum, clicking to higher page numbers, then back to lower page numbers shows all threads without light blue/gray heading as if they have no new posts. Usually this sequence would update the view to show no new posts in the threads I've opened, but leave the unopened ones indicating new posts. It's as if I went back to the Main Index and reentered the forum (which, hm, may have still shown unread threads... or maybe that reset them, I forget).
