# Changelog

# [3.5.0]

## **IMPORTANT! BREAKING CHANGES**

- When upgrading to v3.5 for the first time from v3.4 on a BBQKees Gateway board you will need to use the [EMS-EPS Flasher](https://github.com/emsesp/EMS-ESP-Flasher/releases) 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.
- Support for multiple EMS-ESPs [#759] has been added as an optional setting for MQTT. When enabled, which is now the default, all MQTT Discovery Entity IDs will include the MQTT base name and the shortname of the EMS-ESP device entity. For example what was previously `sensor.boiler_actual_boiler_temperature` will now become `sensor.ems_esp_boiler_boiltemp`. If you still want to use the old format and retain the history and script compatibility in Home Assistant then set this back to the old format.
