Quote - Some of us have absolutely no desire to go to 4.5.  I'm happy with 4.0 until it no longer does what I wants it to do.

However, I think you'll be going to it sooner than later, especially with the dsa formats being depreciated and once the duf and dson format gets finalized. Any new plugins and scenes using that format that you want to buy will probably make you upgrade to 4.5.

I try to stay back a version or two as well, but had to upgrade for the supersuit shaders to work without crashing my app. Once 4.5 is released publicly I'll probably have to deliver material and morphs in the new format for the store for any new character.
