Although I think the new update procedure is one of the best things that came with the 2.9 update, there are so many other great things that came with previous updates that I’m not I sure I can agree to the OP’s statement. I think of snapshots, integration of PowerCab+ Remote, IR referencing and several amp and effect models: Litigator, Derailed Ingrid, Placater, Brit Trem, Revv Gen, Cali Texas, Fullerton, Deranged Master, Kinky Boost, Tone Sovereign/Heir Apparent, Cosmos Echo to name but a few.
And the fun thing is someone else may mention a whole list of other things!
