Problems with Data Types, Low Severity 3

rdkafka.h
[+] enum rd_kafka_resp_err_t 3

	Change	Effect
1	Name of member with value 14 has been changed from RD_KAFKA_RESP_ERR_GROUP_LOAD_IN_PROGRESS to RD_KAFKA_RESP_ERR_COORDINATOR_LOAD_IN_PROGRESS.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Name of member with value 15 has been changed from RD_KAFKA_RESP_ERR_GROUP_COORDINATOR_NOT_AVAILABLE to RD_KAFKA_RESP_ERR_COORDINATOR_NOT_AVAILABLE.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
3	Name of member with value 16 has been changed from RD_KAFKA_RESP_ERR_NOT_COORDINATOR_FOR_GROUP to RD_KAFKA_RESP_ERR_NOT_COORDINATOR.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

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,eos" to "all,generic,broker,topic,metadata,feature,queue,msg,protocol,cgrp,security,fetch,interceptor,plugin,consumer,admin,eos,mock".	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.
