Where are all the patch Notes?

Pressing the > arrow when looking at Warcraft 3, Diablo 3, World of Warcraft etc. there are no patch notes (there’s a Hotfixes for WoW). When I click “News” I scroll down a fair way and there’s still no patch notes mentioned.

When I click … “Forum” it doesn’t give me a choice of game forums to visit, it just takes me here.

How am I supposed to get the information on recent changes to my games? Warcraft 3 updated today and I need to go to the forum to view the patch notes because the Launcher’s latest news item for the game is “The game has launched” which is useless out of date info. How do I access that games forum via the Battle.net Launcher?
