Breaking Changes in v3.6.x~
Warning
The sensors have been renamed. dallassensor is now temperaturesensor in the MQTT topic and named ts in the Customizations file. Likewise analogs is now analogsensor in MQTT and called as in the Customizations file. If you have previous customizations you will need to manually update by downloading, changing the JSON file and uploading. It's also recommended cleaning up any old MQTT topics from your broker using an application like MQTTExplorer.
When upgrading to v3.6 for the first time from v3.4 on a BBQKees Gateway board you will need to use the EMS-EPS Flasher to correctly re-partition the flash. Make sure you backup the settings and customizations from the WebUI (System->Upload/Download) and restore after the upgrade.
