Not sure if anyone has already mentioned this, but the new format does not include the cumulative number of views (as opposed to replies) a thread receives.
For example, back in March 2006 I started a thread on the 7 December 1977 Akrotiri U2 accident. https://www.key.aero/forum/historic-aviation/56680-akrotiri-u2-accident…
I eventually found the answer I was seeking, but curiosity occasionally leads me back to the thread to see if the number of views increases over time – it is simply an indication of ongoing interest in a historical subject.; this applies to any thread. Unfortunately this new version has dropped the facility.
