-## 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

-- Major update for version handling, using `git describe` to fetch version information with git.
-  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/601
-  - Add helper functions provided by [`cmake-modules`](https://github.com/bilke/cmake-modules)
-    manually now. Those should not change too often and only a small subset is needed
-  - Separate folder for easier update and for distinction
-  - LICENSE file included
-  - use `int` for version numbers to allow unset or uninitialized version
-  - Initialize Version object with numbers set to -1
-  - Instead of hardcoding the git hash, it is now retrieved from git
-  - `Version` now allows specifying additional version information like the git SHA1 hash and the
-    versions since the last tag
-  - Additional information is set to the last part of the git describe output for `FSFW_VERSION` now.
-  - Version still need to be hand-updated if the FSFW is not included as a submodule for now.
 - 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/636
-
-**Refactoring general task code**
-
-- There was a lot of duplicate/boilerplate code inside the individual task IF OSAL implementations.
-  Remove it by introducing base classes `PeriodicTaskBase` and `FixedTimeslotTaskBase`.
-
-**Refactor PeriodicTaskIF**
-
-- Convert `virtual ReturnValue_t addComponent(object_id_t object)` to
-  `virtual ReturnValue_t addComponent(object_id_t object, uint8_t opCode = 0)`, allowing to pass
-  the operation code passed to `performOperation`. Updated API taking
-  an `ExecutableObjectIF` accordingly
-
-**Refactor FixedTimeslotTaskIF**
-
-- Add additional `addSlot` function which takes an `ExecutableObjectIF` pointer and its Object ID
-
-**Refactor FixedSequenceSlot**
-
-- Introduce typedef `CustomCheckFunc` for `ReturnValue_t (*customCheckFunction)(const SlotList&)`.
-- Convert `ReturnValue_t (*customCheckFunction)(const SlotList&)` to
-  `ReturnValue_t (*customCheckFunction)(const SlotList&, void*)`, allowing arbitrary user arguments
-  for the custom checker
-
-**Linux Task Module**
-
-- Use composition instead of inheritance for the `PeriodicPosixTask` and make the `PosixTask` a
-  member of the class

   the user compiler supports IPO/LPO. LTO is on by default now. Most modern compilers support it,
   can make good use of it and it usually makes the code faster and/or smaller.

-- 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.

-# CHANGES:
-#
-# 2012-01-31, Lars Bilke
-# - Enable Code Coverage
-#
-# 2013-09-17, Joakim Söderberg
-# - Added support for Clang.
-# - Some additional usage instructions.
-#
-# 2016-02-03, Lars Bilke
-# - Refactored functions to use named parameters
-#
-# 2017-06-02, Lars Bilke
-# - Merged with modified version from github.com/ufz/ogs
-#
-# 2019-05-06, Anatolii Kurotych
-# - Remove unnecessary --coverage flag
-#
-# 2019-12-13, FeRD (Frank Dana)
-# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
-#   of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
-# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
-# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
-# - Set lcov basedir with -b argument
-# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
-#   overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
-# - Delete output dir, .info file on 'make clean'
-# - Remove Python detection, since version mismatches will break gcovr
-# - Minor cleanup (lowercase function names, update examples...)
-#
-# 2019-12-19, FeRD (Frank Dana)
-# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
-#
-# 2020-01-19, Bob Apthorpe
-# - Added gfortran support
-#
-# 2020-02-17, FeRD (Frank Dana)
-# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
-#   in EXCLUDEs, and remove manual escaping from gcovr targets
-#
-# 2021-01-19, Robin Mueller
-# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
-# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
-#   flags to the gcovr command
-#
-# 2020-05-04, Mihchael Davis
-#     - Add -fprofile-abs-path to make gcno files contain absolute paths
-#     - Fix BASE_DIRECTORY not working when defined
-#     - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
-#
-# 2021-05-10, Martin Stump
-#     - Check if the generator is multi-config before warning about non-Debug builds
-#
-# 2022-02-22, Marko Wehle
-#     - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
-#       This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
-#
-# USAGE:
-#
-# 1. Copy this file into your cmake modules path.
-#
-# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
-#    using a CMake option() to enable it just optionally):
-#      include(CodeCoverage)
-#
-# 3. Append necessary compiler flags for all supported source files:
-#      append_coverage_compiler_flags()
-#    Or for specific target:
-#      append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
-#
-# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
-#
-# 4. If you need to exclude additional directories from the report, specify them
-#    using full paths in the COVERAGE_EXCLUDES variable before calling
-#    setup_target_for_coverage_*().
-#    Example:
-#      set(COVERAGE_EXCLUDES
-#          '${PROJECT_SOURCE_DIR}/src/dir1/*'
-#          '/path/to/my/src/dir2/*')
-#    Or, use the EXCLUDE argument to setup_target_for_coverage_*().
-#    Example:
-#      setup_target_for_coverage_lcov(
-#          NAME coverage
-#          EXECUTABLE testrunner
-#          EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
-#
-# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
-#     relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
-#     Example:
-#       set(COVERAGE_EXCLUDES "dir1/*")
-#       setup_target_for_coverage_gcovr_html(
-#           NAME coverage
-#           EXECUTABLE testrunner
-#           BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
-#           EXCLUDE "dir2/*")
-#
-# 5. Use the functions described below to create a custom make target which
-#    runs your test executable and produces a code coverage report.
-#
-# 6. Build a Debug build:
-#      cmake -DCMAKE_BUILD_TYPE=Debug ..
-#      make
-#      make my_coverage_target
-#
