 ## Changes
 
+- HAL Linux SPI: Set the Clock Default State when setting new SPI speed

+  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.

 ## Removed
 
 - Removed the `HkSwitchHelper`. This module should not be needed anymore, now that the local

 ## 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`
