 ## Changes
 
+- Renamed auto-formatting script to `auto-formatter.sh` and made it more robust.
+  If `cmake-format` is installed, it will also auto-format the `CMakeLists.txt` files now.

+### Task Module Refactoring
+
+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.

-## 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.
