 #### Data Gateway
 * Implemented External Services API via MQTT, see [HBNet External Services](https://github.com/kf7eel/hbnet_external_services)
+* Fixed CSBK block generation
 * Implement IPv4/UDP packet generation for SMS
 * SMS data length now variable
-* Added "DMR Standard" format to generated SMS (Used Anytone to reverse engineer, uses UTF-16LE, not UTF-16BE, per ETSI(why?))
+* Added "DMR Standard" format to generated SMS 
+* Add UTF-16BE per ETSI 361-3, should theoretically cover more radios 
 * Added ARS response, still WIP
 * Added dictionary to keep track of subscriber SMS format
+* Add code to detect UDT headers and decode SMS, should now decode Hytera type SMS
+* Add locally executable commands via SMS
 
 #### Web Service
 * Fix APRS settings on registration
 * Add help page for data gateway
+* Fix Pi-Star setup script
+
+#### Notes
+Used Anytone 878  to reverse engineer "DMR Standard", uses UTF-16LE, not UTF-16BE, per ETSI(why?) Also added UTF-16BE as an option.
