IMPORTANT: You must install the filesystem along with the new firmware. Make sure to save your models first!

Incompatibility
Switches are now numbered (e.g.GEAR0, GEAR1). Deviation will properly convert old models, but older versions of Deviation will not properly support models made for version 3.0 or newer
The channel scale is applied after the safety value. If safety is in use, make sure to check the values
The toggle icon locations have changed. Generally all models will need to be reconfigured to use the new icons. This was unintentional, but not easily rectified at this point.
