I favorited our dedicated server and the mark was retained after relogging. A good forward step.
However, unlike before, the server did not appear until the list was full, indicating favorites (and perhaps history) are not prioritized during the polling process. Nor was the favorite highlighted.
As I loosely understand the process, favorites (and perhaps recent history) are polled via their IP first by the client and appear quickly, before general polling takes place. Not happening, sorry.
