+## Changes
+
+- 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.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
+- 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
+- HAL Linux Uart: Baudrate and bits per word are enums now, avoiding misconfigurations
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/585
+- 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
+- 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)
+
+## Removed
+
+- Removed the `HkSwitchHelper`. This module should not be needed anymore, now that the local
+  datapools have been implemented.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/557
+
+## Additions
+
+- Linux HAL: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1
+- Dedicated Version class and constant `fsfw::FSFW_VERSION` containing version information
+  inside `fsfw/version.h`
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/559
+- Added ETL dependency and improved library dependency management
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/592
+
+## Fixed
+
+- Small bugfix in STM32 HAL for SPI
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/599
+- HAL GPIO: Improved error checking in `LinuxLibgpioIF::configureGpios(...)`. If a GPIO
+  configuration fails, the function will exit prematurely with a dedicated error code
