I think, at some point we will all have to face up to the fact, that to carryon getting the latest and greatest features... Backwards compatibility is either going to suffer or have to be dropped.

I know that will not be the prefered for a lot of ppl.. But not much we can do about it. It can be mitigated by converting up old files - as we did with poser 4 files - but at some point even that will be dropped.

(example of this, try running 8bit or 16bit programs in Windows 7 (64bit) and Windows 10.. Not supported at all.)
