CHANGELOG.md

@@ -19,11 +19,19 @@ will consitute of a breaking change warranting a new major release:
 ## Changed
 
 - SCEX filename updates. Also use T as the file ID / date separator between date and time.
+- COM TM store and dump handling: Introduce modes for all 4 TM VC/store tasks. The OFF mode can be
+  used to disable ongoing dumps or to prevent writes to the PTME VC. This allows cleaner reset
+  handling of the PTME. All 4 VC/store tasks were attached to the COM mode tree and are commanded
+  as part of the COM sequence as well to ensure consistent state with the CCSDS IP core handler.
+- Added `PTME_LOCKED` boolean lock which is used to lock the PTME so it is not used by the VC tasks
+  anymore. This lock will be controlled by the CCSDS IP core handler and is locked when the PTME
+  needs to be reset. Examples for this are datarate changes.
 
 ## Fixed
 
 - Bugfix for side lane transitions of the dual lane assemblies, which only worked when the
   assembly was directly commanded
+- Syrlinks Handler: Bugfix so transition command is only sent once.
 
 ## Added
