@ -33,10 +33,22 @@ will consitute of a breaking change warranting a new major release:
  CMake from selecting wrong cross-compilers if multiple cross-compilers with the same name are used
  on the same system.
 - Add ACS board for EM by default now.
+- Add support for MPSoC HK packet.
+- Add support for MPSoC Flash Directory Content Report.
+- Dynamically enable and disable HK packets for MPSoC on `ON` and `OFF` commands.
+- Add support for MPSoC Flash Directory Content Report.
+- Larger allowed path and file sizes for STR and PLOC MPSoC modules.
+- More robust MPSoC flash read and write command data handling.
+- Increase frequency of payload handlers from 0.8 seconds to 0.5 seconds.
+- Disable missed deadlines per default. Not useful in orbit, and triggers all the time on the EM
+  build after a number of subsequent runs, without any apparent reason (deadlines are not actually
+  missed, thread usage displayed is nominal)

 ## Added

 - Add the remaining system modes.
+- PLOC MPSoC flash read command working.
+- BPX battery handler is added for EM by default.

 ## Fixed

@ -46,6 +58,16 @@ will consitute of a breaking change warranting a new major release:
  16505 type.
 - Host build is working again. Added reduced live TM helper which schedules the PUS and CFDP
  funnel.
+- PLOC Supervisor handler now has a power switcher assigned to make PLOC power switching work
+  without an additional PCDU power switch command.
+- The PLOC Supervisor handler now waits for the replies to the `SET_TIME` command to verify working
+  communication.
+- The PLOC MPSoC now waits 10 cycles before going to on. These wait cycles are necessary because
+  the MPSoC is not ready to process commands without this additional boot time.
+- Fixed correction for `GPS Altitude` in case the sensor data is out of the expected bonds.
+- PLOC MPSoC special communication is now scheduled, which allows flash read and flash write
+  commands to work.
+- Fixed the MPSoC flash write command.
