I only use old version. Today, I noticed that, as usual, I only had several news notification when logging on. When I clicked the "News" tab, the new unread items suddenly increase to 152. Types of many such items were never shown as unread before.

Is it a bug? I think probably it is not. As I remember, I have a lot of unread notifications when I logon new version. Is this a change to synchronize News tab settings of 2 versions?
