7.4 also breaks renders over 10 minutes long (that's rendering time, not project time) in After Effects, and misc. problems have been reported with pre-FCPStudio2 Apple Pro products as well, though its the After Effects problem that is significant. Workaround if you already upgraded is to install 7.3.1 using Pacifist, though apparently this has to be done very carefully.
