Did threaded view disappear with the update? I no longer see reply buttons on individual posts, and no longer see any options to change the view mode...

For Today's Posts, use 'New Topics' from the top sub menu bar on Home / Forum page.
For 'subscribed threads', select 'My Subscriptions' from the main forum page:
