ER 101 Firmware Update

I was doing my annual scrub for firmware updates and noticed that the change log for the ER 101 goes up to 2.09 which I do have on mine but digging through the code noticed the current build would classify as 2.10. Does anyone know what changes were made? I haven’t built out a firmware from a makefile in a long time so just trying to determine if it is worth it ;D

Still the king of the sequencers!!!
