What's fixed:

1. "Detect control units" in the Android app caused "internal error"
2. MR parameters write (in some cases values restored back after ECU power off/on)
3. Scania faults read was improved (now more ECU are supported)

11. TCM unpairing (was unavailable for immo systems other than FBS3)
12. Some EIS versions were not detected (hardware type was detected as "unknown")
13. Connect to device on some new Android v12 phones now works ok (was error "device not found" immediately) 
14. CPC/CPC4 (Kamaz/Mercedes bus/Freightliner) via DC connect was ok but other diagnostic operations failed with "error 3.5"
