See wiki migration path for instructions how to migrate to a major version. Pay attention to the following version breaks due to dynamic settings updates:
Firmware binary sonoff-classic.bin supports WifiManager, Wps and SmartConfig for initial configuration. The default tool is Wps.
To save memory space all other binaries support WifiManager only.
See _changelog.ino how to enable them again.
