 ## Fixed
 
+- Star Tracker: OFF to NORMAL transition now posssible. Requires FSFW bump which sets
+  transition source modes properly for those transitions.
+  FSFW PR: https://egit.irs.uni-stuttgart.de/eive/fsfw/pulls/131
+- Star Tracker JSON initialization is now done during object initization instead of redoing it
+  when building a command. This avoids missed deadlines issues in the ACS PST.
 - Allow arbitrary submodes for dual lane boards to avoid FDIR reactions of subsystem components.
   Bump FSFW to allow this.
 - PUS 15 was not scheduled
