New firmware issue

I have a gig coming up soon and have many MIDI programs that I use from the U24. Could any one please let me know if the new firmware is safe to use now? Any updates on its progress? Right now I’m using the firmware just below the new one and when I use the playlist the mixer settings stay the same from the 1st song all the way through…as it doesn’t change on what we had set for each song. The mixer setting will only change to what we programmed it when we hit the stop button.
