Hello, it’s been some time since I’ve messed with my Maslow 4 and broke it out of storage. I’m on version 0.88 of the firmware. Am I safe to OTA [v1.20](https://github.com/MaslowCNC/Maslow_4/releases/tag/v1.20) or should I stick to USB?

to pass the 1.0 line you need to do it via USB, after that you can do ITA  
updates again
