When the switch to the new software was made, Suggested Topics would differentiate between new posts in a topic, and ones that were there the last time I visited the thread.
Example: A thread has 50 posts when I open it the first time and I read 30 of them before closing the topic. 15 more posts are entered and when the topic shows at the bottom of the page, it has 30 in gray circle and 15 in blue.
Now, new or old, it would just shows 45 in a blue circle.
Was there an update or did I jigger something in a setting somewhere?
