 - HAL Devicehandlers: Periodic printout is run-time configurable now
 - `oneShotAction` flag in the `TestTask` class is not static anymore
+- 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
+  - Place `Version` class outside of `fsfw` namespace. It is generic
+  - 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

   the user compiler supports IPO/LPO. LTO is on by default now. Most modern compilers support it,

+- 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.

+# 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
+#

+ * overriding two provided virtual methods. This also allows detecting multiple DLE packets
