Had the nice surprise 1.14.4 has been released with some big fixing.
Most noticeably there is mention to 2.6.2 framework support and some notes about Esp32 BLE fix/improvement and Esp8266 WiFi improvements if I correctly understood.
Not sure though which is now default arduino framework.
Also I couldn’t find any post/indication if firmware upgrade is suggested (for WiFi/BLE stability) and in case which is suggested arduino framework.
Last upgrade brought few issues to WiFi connectivity hence I am not reluctant to experiment!
