This is mostly a bug fix release. The following fixes are in v3.0.1:
- functions with vector arguments don't work
- let() function inside a user function fails
- Windows command-line version reports the wrong version number
- Memory corruption occurs if the background is not opaque, results in random errors
- Visible seams on tiled images that have very small shapes at the tile edge
- Variations totally broken due to uninitialized data bug
- Command-line version cannot generate anything but QuickTime output, see viewtopic.php?f=10&t=968#p3683
- Natural number parameters for function calls and shape invocations now must be less that CF::MaxNatural
- The new isNatural(x) function returns true is x is a legal natural number
