- Use simple string concatenation instead of String.format() - Rewrite exception messages so that it follows our style - Merge MqttCommonUtil and MqttValidationUtil into MqttCodecUtil - Hide MqttCodecUtil from users - Rename MqttConnectReturnCode.value to byteValue - Rename MqttMessageFactory.create*() to new*() - Rename QoS to MqttQoS - Make MqttSubAckPayload.grantedQoSLevels immutable and add more useful constructor
