 ## Fixes
 
+- `CService200ModeManagement`: Various bugfixes which lead to now execution complete being generated
+  on mode announcements, duplicate mode reply generated on announce commands, and the mode read
+  subservice not working properly.
+- `Service9TimeManagement`: Fix the time dump at the `SET_TIME` subservice: Include clock timeval
+  seconds instead of uptime.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/726
+- HAL MGM3100 Handler: Use axis specific gain/scaling factors. Previously,
+  only the X scaling factor was used.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/724
+- DHB `setNormalDatapoolEntriesInvalid`: The default implementation did not set the validity
+  to false correctly because the `read` and `write` calls were missing.
+- PUS TMTC creator module: Sequence flags were set to continuation segment (0b00) instead
+  of the correct unsegmented flags (0b11) as specified in the standard.
+- TC Scheduler Service 11: Add size and CRC check for contained TC.
+- Only delete health table entry in `HealthHelper` destructor if
+  health table was set.

   Also properly reset the reply size for successfull transfers and erroneous transfers.

 ## Added
 
-- DHB TM handler `handleDeviceTM` renamed to `handleDeviceTm` and now takes
-  `util::DataWrapper` as the data input argument. This allows more flexibility in the possible
-  types of telemetry.
-  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/669
-- Add `util::DataWrapper` class inside the `util` module. This is a tagged union which allows
-  to specify raw data either as a classic C-style raw pointer and size or as a `SerializeIF`
-  pointer.

+  PR: https://egit.irs.uni-stuttgart.de/eive/fsfw/pulls/122
+- `Service9TimeManagement`: Add `DUMP_TIME` (129) subservice.
+- `TcpTmTcServer`: Allow setting the `SO_REUSEADDR` and `SO_REUSEPORT`
+  option on the TCP server. CTOR prototype has changed and expects an explicit
