# [3.5.0] February 6 2023

## **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.
