Problems with Data Types, Low Severity 1

rdkafka.h
[+] enum rd_kafka_resp_err_t 1

	Change	Effect
1	Value of member RD_KAFKA_RESP_ERR_END_ALL has been changed from 56 to 75.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

[+] affected symbols: 93 (39.9%)

Problems with Constants, Low Severity 1

	Change	Effect
1	The value of constant RD_KAFKA_DEBUG_CONTEXTS has been changed from "all,generic,broker,topic,metadata,feature,queue,msg,protocol,cgrp,security,fetch,interceptor,plugin,consumer,admin" to "all,generic,broker,topic,metadata,feature,queue,msg,protocol,cgrp,security,fetch,interceptor,plugin,consumer,admin,eos".	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
