-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

   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.
