 ## Version History
 
+### Development Build: v6.8.0-rc1+dev580
+
+- Adds `CFE_MSG_GetNextSequenceCount` so the auto-increment of the local sequence counter works when sending tlm (and increment is enabled). Updates unit tests and adds the old-style stub. The unit tests check for the correct rollover behavior.Sequence count will roll over based on the mask. Before the fix the sequence counter would "stick" in telemetry until the passed in value rolled over.
