 ## Additions
 
-- Linux HAL: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1
 - Dedicated Version class and constant `fsfw::FSFW_VERSION` containing version information
   inside `fsfw/version.h`
   PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/559
 - Added ETL dependency and improved library dependency management
   PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/592
+- `Subsystem`: New API to add table and sequence entries
+
+## 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.
 
 ## Fixed
 
+- TCP TMTC Server: `MutexGuard` was not created properly in
+  `TcpTmTcServer::handleTmSending(socket_t connSocket, bool& tmSent)` call.
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/618
+- Fix infinite recursion in `prepareHealthSetReply` of PUS Health Service 201.
+  Is not currently used right now but might be used in the future
+  PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/617
+- Move some CMake directives further up top so they are not ignored
