 # [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
-  for other modules
-  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/655
-  which also includes a migration guide

 - `Subsystem`: New API to add table and sequence entries
 
-## 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.
