v4.1

• ATTENTION: BREAKING CHANGE! Changed topic structure for MQTT. This means that all existing MQTT entities in your home-automation system will have to be adjusted or created anew! The new structure now is BSB-LAN/<device id>/<category id>/<parameter number>.
• ATTENTION: BREAKING CHANGE! Changed unique_id for MQTT auto-discovery. This means that all MQTT entities that have been created via auto-discovery will have to be created anew!
• ATTENTION: Configuration options fixed_device_family and fixed_device_variant have been removed since they no longer work for device-specific parameter lists. If your heating system is off when turning on the microcontroller, BSB-LAN will try to acquire the details every 60 seconds.
• ATTENTION: Change of configuration options results in new EEPROM layout, therefore EEPROM will be reinitialized based on configuration of BSB_LAN_config.h.
• MQTT auto-discovery now works for all devices, not only device ID 0. Use /M1!<x> or /M0!<x> to create/remove entities for device ID <x>.
• Changed MQTT auto-discovery messages' flag to "retain" so that parameters remain available after reboot of Home Assistant.
