5.2.1 20170622

• Fix Restore Configuration in case of lower version
• Revert auto configuration upgrade allowing easy upgrade which was removed in version 5.2.0
• Add command SetOption12 1 to disable newly released configuration flash rotate to reduce flash wear

• Fix config auto upgrade from versions below version 4.1.1 (#530)

New feature

This versions introduces dynamic usage of configuration flash providing reduced flash wear. It saves configurations in different flash locations. When an OTA or web upgrade is initiated a backup of the configuration is stored in the eeprom area before the upgrade takes place. Seven additional flash pages are used lowering normal flash wear considerably.
This feature is default ON. With command SetOption12 1 it can be disabled.
