 ## Changed
 
-- Remove 2 TCS threads.
-- Move low level polling into ACS PST, move high level device handlers into TCS system task.
+- Remove 2 TCS threads. Move low level polling into ACS PST, move high level device handlers into
+  TCS system task.
+- Further reduce number of threads:
+  1. Remove PUS low priority task, move assigned threads to the generic system task
+  2. Group events and verification tasks into PUS high priority task
+  3. Group all other components into PUS medium priority task
+  4. Add SCEX device handler to PL task, remove dedicated thread
+
+## Added
+
+- Tracing supports which allows checking whether threads are running as usual.
 
 ## Removed
