Compressor/limiter Vs. Shaper?

The manual only mentions the Shaper. What’s the difference between this and the Compressor/Limiter? (e.g. Is the Shaper an poorer compressor only included for backwards compatibility?)

Yes, petty much so…t=ST&f=6&t=1948
it was brought back in 1.27…t=ST&f=3&t=2664

Cheers Twilek. Will have to mess around with it to appreciate the distortion referred to.
