-# Changed from ASTP 1.1.0 to 1.2.0
-
-## API Changes
-
-### FSFW Architecture
-
-- New src folder which contains all source files except the HAL, contributed code and test code
-- External and internal API mostly stayed the same
-- Folder names are now all smaller case: internalError was renamed to internalerror and
-  FreeRTOS was renamed to freertos
-- Warning if optional headers are used but the modules was not added to the source files to compile
-
-### HAL
-
-- HAL added back into FSFW. It is tightly bound to the FSFW, and compiling it as a static library
-  made using it more complicated than necessary
-
-## Bugfixes
-
-### FreeRTOS QueueMapManager
-
-- Fixed a bug which causes the first generated Queue ID to be invalid
-
-## Enhancements
-
-### FSFW Architecture
-
-- See API changes chapter. This change will keep the internal API consistent in the future
-
-# Changes from ASTP 1.0.0 to 1.1.0
-
-## API Changes
-
-### PUS
-
-- Added PUS C support
-- SUBSYSTEM_IDs added for PUS Services
-- Added new Parameter which must be defined in config: fsfwconfig::FSFW_MAX_TM_PACKET_SIZE
-
-### ObjectManager
-
- - ObjectManager is now a singelton
-
-
-### Configuration
-
-- Additional configuration option fsfwconfig::FSFW_MAX_TM_PACKET_SIZE which 
-  need to be specified in FSFWConfig.h
-
-### CMake
-
-- Changed Cmake FSFW_ADDITIONAL_INC_PATH to FSFW_ADDITIONAL_INC_PATHS
-
-## Bugfixes 
-
-- timemanager/TimeStamperIF.h: Timestamp config was not used correctly, leading to different timestamp sizes than configured in fsfwconfig::FSFW_MISSION_TIMESTAMP_SIZE
-- TCP server fixes
-
-## Enhancements
-
-### FreeRTOS Queue Handles
-
-- Fixed an internal issue how FreeRTOS MessageQueues were handled
-
-### Linux OSAL
-
-- Better printf error messages
-
-### CMake
-
-- Check for C++11 as mininimum required Version
-
-### Debug Output
-
-- Changed Warning color to magenta, which is well readable on both dark and light mode IDEs
-
-
-# Changes from ASTP 0.0.1 to 1.0.0
-
-### Host OSAL
-
-- Bugfix in MessageQueue, which caused the sender not to be set properly
-
-### FreeRTOS OSAL
-
-- vRequestContextSwitchFromISR is declared extern "C" so it can be defined in
-a C file without issues
-
-### PUS Services
-
-- It is now possible to change the message queue depth for the telecommand verification service (PUS1)
-- The same is possible for the event reporting service (PUS5)
-- PUS Health Service added, which allows to command and retrieve health via PUS packets
-
-
-### EnhancedControllerBase
-
-- New base class for a controller which also implements HasActionsIF and HasLocalDataPoolIF
-
-### Local Pool
-
-- Interface of LocalPools has changed. LocalPool is not a template anymore. Instead the size and
-bucket number of the pools per page and the number of pages are passed to the ctor instead of
-two ctor arguments and a template parameter
-
-### Parameter Service
-
-- The API of the parameter service has been changed to prevent inconsistencies
-between documentation and actual code and to clarify usage.
-- The parameter ID now consists of:
-	1. Domain ID (1 byte)
-	2. Unique Identifier (1 byte)
-	3. Linear Index (2 bytes)
-The linear index can be used for arrays as well as matrices.
-The parameter load command now explicitely expects the ECSS PTC and PFC
-information as well as  the rows and column number. Rows and column will
-default to one, which is equivalent to one scalar parameter (the most
-important use-case)
-   
-### File System Interface
-
-- A new interfaces specifies the functions for a software object which exposes the file system of
-a given hardware to use message based file handling (e.g. PUS commanding)
-
-### Internal Error Reporter
-
-- The new internal error reporter uses the local data pools. The pool IDs for
-the exisiting three error values and the new error set will be hardcoded for
-now, the the constructor for the internal error reporter just takes an object
-ID for now.
-
-### Device Handler Base
-
-- There is an additional `PERFORM_OPERATION` step for the device handler base. It is important
-that DHB users adapt their polling sequence tables to perform this step. This steps allows for 
-a clear distinction between operation and communication steps
-- setNormalDatapoolEntriesInvalid is not an abstract method and a default implementation was provided
-- getTransitionDelayMs is now an abstract method
-
-### DeviceHandlerIF
-
-- Typo for UNKNOWN_DEVICE_REPLY 
-
-### Events
-
-- makeEvent function: Now takes three input parameters instead of two and
-allows setting a unique ID. Event.cpp source file removed, functions now
-defined in header directly. Namespaces renamed. Functions declared `constexpr`
-now
-
-### Commanding Service Base
-
-- CSB uses the new fsfwconfig::FSFW_CSB_FIFO_DEPTH variable to determine  the FIFO depth for each 
-CSB instance. This variable has to be set in the FSFWConfig.h file
-
-### Service Interface
-
-- Proper printf support contained in ServiceInterfacePrinter.h
-- CPP ostream support now optional (can reduce executable size by 150 - 250 kB)
-- Amalagated header which determines automatically which service interface to use depending on FSFWConfig.h configuration. 
-  Users can just use #include <fsfw/serviceinterface/ServiceInterface.h>
-- If CPP streams are excluded, sif:: calls won't work anymore and need to be replaced by their printf counterparts. 
-  For the fsfw, this can be done by checking the processor define FSFW_CPP_OSTREAM_ENABLED from FSFWConfig.h. 
-  For mission code, developers need to replace sif:: calls by the printf counterparts, but only if the CPP stream are excluded. 
-  If this is not the case, everything should work as usual.
-
-### ActionHelper and ActionMessage
-
-- ActionHelper finish function and ActionMessage::setCompletionReply now expects explicit 
-information whether to report a success or failure message instead of deriving it implicitely 
-from returnvalue
-
-### PUS Parameter Service 20
-
-Added PUS parameter service 20 (only custom subservices available).

+
+## Changes
+
+- HAL Linux SPI: Set the Clock Default State when setting new SPI speed
+  and mode
+  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.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
+- New CMake option `FSFW_HAL_LINUX_ADD_LIBGPIOD` to specifically exclude `gpiod` code.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
+- HAL Devicehandlers: Periodic printout is run-time configurable now
+- `oneShotAction` flag in the `TestTask` class is not static anymore
+- HAL Linux Uart: Baudrate and bits per word are enums now, avoiding misconfigurations
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/585
+- 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
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/583
+- Clock: 
+  - `timeval` to `TimeOfDay_t`
+  - Added Mutex for gmtime calls: (compare http://www.opengate.at/blog/2020/01/timeless/)
+  - Moved the statics used by Clock in ClockCommon.cpp to this file
+  - Better check for leap seconds
+  - Added Unittests for Clock (only getter)
+
+## Removed
+

+```cpp
+git clone https://github.com/ETLCPP/etl
+cd etl
+git checkout <currentRecommendedVersion>

+## Building the documentations
+
+The FSFW documentation is built using the tools Sphinx, doxygen and breathe based on the
+instructions provided in  [this blogpost](https://devblogs.microsoft.com/cppblog/clear-functional-c-documentation-with-sphinx-breathe-doxygen-cmake/). If you
+want to do this locally, set up the prerequisites first. This requires a ``python3``

+```sh
+sudo apt-get install doxygen graphviz
+```
+
+And the following Python packages
+
+```sh
+python3 -m pip install sphinx breathe
+```
+
+You can set up a documentation build system using the following commands
+
+```sh
+mkdir build-docs && cd build-docs
+cmake -DFSFW_BUILD_DOCS=ON -DFSFW_OSAL=host ..
+```
+
+Then you can generate the documentation using
+
+```sh
+cmake --build . -j
+```
+
+You can find the generated documentation inside the `docs/sphinx` folder inside the build
+folder. Simply open the `index.html` in the webbrowser of your choice.
+
+The `helper.py` script located in the script` folder can also be used to create, build

+#
+# 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
+#

 Device Handlers
 ==================
 
+Device handler components represent, control and monitor equipment, for example sensors or actuators
+of a spacecraft or the payload.
+
+Most device handlers have the same common functionality or
+requirements, which are fulfilled by implementing certain interfaces:
+
+- The handler/device needs to be commandable: :cpp:class:`HasActionsIF`
+- The handler needs to communicate with the physical device via a dedicated
+  communication bus, for example SpaceWire, UART or SPI: :cpp:class:`DeviceCommunicationIF`
+- The handler has housekeeping data which has to be exposed to the operator and/or other software
+  components: :cpp:class:`HasLocalDataPoolIF`
+- The handler has configurable parameters: :cpp:class:`ReceivesParameterMessagesIF` which
+  also implements :cpp:class:`HasParametersIF`
+- The handler has health states, for example to indicate a broken device:
+  :cpp:class:`HasHealthIF`
+- The handler has modes. For example there are the core modes `MODE_ON`, `MODE_OFF`
+  and `MODE_NORMAL` provided by the FSFW. `MODE_ON` means that a device is physically powered
+  but that it is not periodically polling data from the
+  physical device, `MODE_NORMAL` means that it is able to do that: :cpp:class:`HasModesIF`
+
+The device handler base therefore provides abstractions for a lot of common
+functionality, which can potentially avoid high amounts or logic and code duplication.

+   cd etl
+   git checkout <currentRecommendedVersion>
+   mkdir build && cd build
+   cmake ..

 Adding the library

+You can install the Catch2 library, which prevents the build system to avoid re-downloading
+the dependency if the unit tests are completely rebuilt. The current recommended version
+can be found inside the fsfw ``CMakeLists.txt`` file or by using ``ccmake`` and looking up
