Problems with the MB1200 XL-MaxSonar-EZ0 analog sonar and frameware 3.5.0 rc4

Problems with the MB1200 XL-MaxSonar-EZ0 analog sonar and frameware 3.5.0 rc4
When I installed 3.5.0rc2 the sonar worked normally but after upgrading to 3.5.0 rc3 the sonar stopped working.
If I install a stable version (3.4.6 last version) the sonar works normally
In version 3.5.0 rc4 I got to reset all parameters the sonar returned to work but after I did the calibration of compass and initial wizard the sonar stopped working again.
I think it’s a failure on RC4

I USE QUADCOPTER AND FRONT SONAR

sonar range and sonar volt = 0
