 # [unreleased]
 
+# [v6.0.0]
+
+## 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/fsfw/fsfw/pulls/668
+- Add new `UnsignedByteField` class
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/660
+
 ## Changes
 
 - Removed `HasReturnvaluesIF` class in favor of `returnvalue` namespace with `OK` and `FAILED`
   constants.
   PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/659

+- Overhaul of the TMTC stack, including various changes and improvements
-## Added

+## HAL
+
+- SPI: Cache the SPI device in the communication interface. Architecturally, this makes a
+  lot more sense because each ComIF should be responsible for one SPI bus.
+- SPI: Move the empty transfer to update the line polarity to separate function. This means
+  it is not automatically called when calling the setter function for SPI speed and mode.
+  The user should call this function after locking the CS mutex if multiple SPI devices with
+  differing speeds and modes are attached to one bus.
+- SPI: Getter functions for SPI speed and mode.
+- I2C: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1.
