The latest update changes the interface so that the ABCD etc. is replaced with a search box for both patches and modules.
You might find this a big improvement over the prevoius interface, but if you are used to the old way and would find such a huge change difficult to accept I'd avoid updating.
Unless I'm missing something it's also impossible to revert to an old firmware version (without dissembling the pedal parhaps) so if you change to the new interface you're stuck with it.
For me it's made everything way harder to use, and I'm not the only one pissed off with it so hopefully there will be some sort of resolution, but I'm not going to be expecting anything anytime soon.
