Erick, that's not how plug-ins work. We change our SDK roughly once every two years (though we did change it last year too). When we change our SDK, then people who create plug-ins have to update their plug-ins to work with our new release. It has always been this way, there is nothing we can do other than not ever change our SDK. If you don't ever want new features, then that would work fine.
I think issues with BB were addressed. I don't remember the beta claiming we had problems when we issued the last beta drop. The first service pack will be sooner than later (within a month or so of the release). Our goal is to provide more frequent updates to those that can digest them. Stay tuned.
