 # [unreleased]

+## Changed
+
+- Reworked MPSoC handler to be compatible to new MPSoC software image and use 
+  new device handler base class. This should increase the reliability of the communication
+  significantly.
+- MPSoC device modes IDLE, SNAPSHOT and REPLAY are now modelled using submodes.
+- Commanding a submode the device is already in will not result in a completion failure
+  anymore.
+
+## Added
+
+- Added `VERIFY_BOOT` command for MPSoC.
+- New command for MPSoC to store camera image in chunks.
+
 # [v7.8.1] 2024-04-11

 - Reverted fix for wrong order in quaternion multiplication for computation of the error quaternion.
