ESP8266 RAM Optimization
Experimental release - For a stable ESP8266 experience, use v1.8.5.
Changes
- Disabled ArduinoOTA on ESP8266 to free RAM for more critical functions
- ArduinoOTA ran as a background UDP service consuming memory unnecessarily
- ESP8266 already has web-based Safe Update mode for OTA updates
- ESP32 and ESP32-C3 retain ArduinoOTA (plenty of RAM available)
