Software evolves, changes, improves. It is the nature of things. I agree with what parkdalegardener writes above in large part. I got the upgrade k iwing 3rd party Python apps that used to work seamlessly in previous versions won't operate any more and am waiting for when those can be back. What caught me unawares, and I hazard many others, was the broken shaders for Superfly that worked in Superfly literally two weeks ago. The speed and stability of P12 is great, and the bugs eventually will be ironed out. Early release and community bugstamping is working, as evidenced by the first service release. Now just hoping for better promo renders for released products so they are actually attractive to buy as opposed to 'buying to support the release based on hopes, not looks'.
