- Add createPermanentConnections argument to attemptAutoEncryptingTransmission method.
- Reduce risk of misinterpreting acks by adding check for ack sender MAC.
- Reduce _encryptionRequestTimeoutMs from 500 ms to 300 ms since this should give enough (100 %) margin to the level where problems start appearing (150 ms timeout) and also save a lot of time in case of request failure.
- Improve comments.
- Add HelloEspnow.ino example to demonstrate the ESP-NOW mesh backend features.
- Deprecate the ESP8266WiFiMesh class in favour of the new ESP-NOW and TCP/IP backends.
- Update the TCP/IP mesh backend to use the new lwIP version preprocessor flag and remove obsolete preprocessor flags.
