+* SoftAP mode added for configuration possibility on a new WiFi (hold button A and then click reset on M5Stack models with mechanical buttons, touch button A while you see CONFIG progress during boot on M5Stack Core2). 
+* No SD card needed. When you save configuration from the web interface, it is saved to both - SD card and internal flash memory. You can then remove the SD card and reboot. To archive your settings to SD card, insert SD card and save configuration from web interface.  
+* If you start blank M5Stack just programmed with M5 Nightscout Monitor firmware, it will enter the SoftAP mode directly for easy web configuration.  
+* SSID name length extended to 63 characters.
