 ## Changed
 
+- ACS-Board default side changed to B-Side
 - The TLE uploaded now gets stored in a file on the filesystem. It will always be stored on
   the current active SD Card. After a reboot, the TLE will be read from the filesystem.
   A filesystem change via `prefSD` on bootup, can lead to the TLE not being read, even
   though it is there.
 
+# [v7.4.0] 2023-12-XX

 ## Changed
 
 - Rewrote the PLOC Supervisor Handler, which is now based on a new device handler base class.
