Framecpp-3.0.1 FrVect::compress does not recognize mode 0x03 (zero-suppress or gzip)

I get the following exception when trying to set the FrVect compression mode to 0x03:

Exception writing final trend: compression: unknown compression mode: 3(0x3) (DEBUG: 19c size: 5)

I used the following instruction:

mVect->Compress(FrVect::ZERO_SUPPRESS_OTHERWISE_GZIP, 1);
