This is the list of changes since release v3.3.

1. Important Notes

  • Removed aws-iot component and related example, if you need to implement aws-iot, please refer to https://github.com/espressif/esp-aws-iot.
  • Removed ibm-mqtt component and related example, if you need to implement MQTT, please refer to https://github.com/espressif/esp-mqtt.
