 # [unreleased]
 
+## Fixed
+
+- STR config path was previously hardcoded to `/mnt/sd0/startracker/flight-config.json`.
+  A new abstraction was introduces which now uses the active SD card to build the correct
+  config path when initializing the star tracker.
+
+## Added
+
+- Introduced a new `RELOAD_JSON_CFG_FILE` command for the STR to reload the JSON configuration
+  data based on the current output of the config file path getter function. A reboot of the
+  device is still necessary to load the configuration to the STR.
