 # [unreleased]
 
+## Changed
+
+- Readded calibration matrices for MGM calibration
+
 ## Fixed
 
 - Build system: Fixed small bug, where the version itself was
   stored as the git SHA hash in `commonConfig.h`. This will be
   an empty string now for regular versions.
 - Bump FSFW for important fix in PUS mode service.
+- Bugfixes in 'SensofProcessing' where previously MGM values would be calibrated before being
+  transformed in body RF. However, the calibration values are in the body RF. Also fixed the
+  validity flag of 'mgmVecTotDerivative'.
