@@ -19,6 +19,11 @@ will consitute of a breaking change warranting a new major release:
 ## 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.
+- Added action cmd to read the currently stored TLE.
