+- Linux HAL: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1
-  This is also the new default constructor for scalar value with 0 as an initial value

-  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/625
-- LTO support: Allow using LTO/IPO by setting `FSFW_ENABLE_LTO=1`. CMake is able to detect whether
-  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.
-  After some more research:
-  Enabling LTO will actually cause the compiler to only produce thin LTO by adding 
-  `-flto -fno-fat-lto-objects` to the compiler options. I am not sure this is an ideal choice
-  because if an application linking against the FSFW does not use LTO, there can be compile
-  issues (e.g. observed when compiling the FSFW tests without LTO). This is a known issue as
-  can be seen in the multiple CMake issues for it:

-    - https://gitlab.kitware.com/cmake/cmake/-/issues/16808,

-## 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.
