Wilbur 1.88 is out at http://www.fracterra.com/software.html for interested parties (or even apathetic parties; I won't judge you for your feelings about my software children). Very little new, but the V2 shader should work correctly for negative latitudes and it's now compiled with Visual C++ 2017 for theoretically better code generation. I'm considering dropping support for the 32-bit version because I have to push a couple of extra buttons to keep all of that stuff synchronized.

There's also a new version of ReprojectImage (1.1) available at http://www.fracterra.com/ReprojectImage.zip in the unlikely event anyone uses it.
