How it it Microsoft's problem if Apple made incompatible changes in a minor release?

Apple breaks things right and left - and the fans always blame the third parties for Apple's screw-ups.

It's not Apple's job to make sure other's software works. They change the OS to how they want, then others fix their software to work with it. It's the same with Windows, so don't get your panties in a wad.

It *is* Apple's job to support an API that Apple has published for developers.
Wrong, we are talking about BETA software here, it's not up to Apple to make sure anything is compatible with exception of their own stuff upon release.
