New DPP 4.5.20.0 finally adds support for 5D classic

YES, now I can play around with my old xti & 50D shots without having to switch from DPP 4 to DPP 3...

So what are we upset about again? This is a very common software practice. There is a point that an old package is too hard to support, and even harder to change over to something new, so a new baseline is started.

By "...an old package is too hard to support..." we mean paying developers to keep their heads in old software that will not be used for any new purposes.

True

However it does show that the old DPP was "modular" enough that they were able to adapt the old raw models from DPP3 into the DPP4 framework. I suspect they started with the initial requirement that nothing old would be supported, but then as they worked through the conversion framework, they found they could bring over DPP3 core routines with little work.
