I emailed Magmic (who coded NYT Crosswords) last week and sent them my device logs. They said they found the bug last Monday and have an update submitted to App Store. Hopefully we'll see it soon -- it still crashes for me right after launching it.
I'm also a bit worried that now I can't actually sync with iTunes -- I did an update from beta 3 to the GM and after it rebooted now it won't sync with iTunes. It tells me I need iTunes 10.1 to be able to sync. *Great*.
Errr... never mind. Found the 10.1 beta for Mac on the iOS Dev Center so I'm good.
Netflix works again -- yippee
