If I have understood the release note in the right way, we have to reload the amps (double Bypass)?.
From the release notes:
Improved triode saturation modeling based on new measurements. The new modeling results in more accurate saturation behavior which, in turn, results in smoother overall distortion characteristics and more accurate harmonic content. Due to the new algorithm the default Preamp Hardness value is now 6.0. Existing presets are automatically updated upon recall.
