Yes. This would be a lot easier than posting another topic every time there are a few bug fixes.
Nah, these should still stay.
They're informative, and are the place where the update will get the most attention.
It's also where Badspot can give any more news on each update, and reply to people's comments.
And it gives a place where people can come to and see if there are any common bugs with the game, and share them.
But the "What's New" button is a great idea.
Even if it was just opening your default browser and directing it to the update topic.
Might also lure some more of the players who don't browse the forums or didn't know they existed.
