 ## Changes
 
+
+- New CMake option `FSFW_HAL_LINUX_ADD_LIBGPIOD` to specifically exclude `gpiod` code.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
+- HAL Devicehandlers: Periodic printout is run-time configurable now
+- `oneShotAction` flag in the `TestTask` class is not static anymore
+- IPC Message Queue Handling: Allow passing an optional `MqArgs` argument into the MessageQueue
+  creation call. It allows passing context information and an arbitrary user argument into
+  the message queue. Also streamlined and simplified `MessageQueue` implementation for all OSALs
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/583
+
+### HAL
+
 - HAL Linux SPI: Set the Clock Default State when setting new SPI speed
   and mode
   PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/573
 - GPIO HAL: `Direction`, `GpioOperation` and `Levels` are enum classes now, which prevents
   name clashes with Windows defines.

-- Clock: 
-  - `timeval` to `TimeOfDay_t`
-  - Added Mutex for gmtime calls: (compare http://www.opengate.at/blog/2020/01/timeless/)
-  - Moved the statics used by Clock in ClockCommon.cpp to this file
-  - Better check for leap seconds
-  - Added Unittests for Clock (only getter)

+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/590
+- Extend `PowerSwitcher` module to optionally check current state when calling `turnOn` or
+  `turnOff`. Tis can be helpful to avoid commanding switches which do not need commanding
