Problems with Data Types, Medium Severity 1

	Change	Effect
1	Value of member RD_KAFKA_ADMIN_OP__CNT has been changed from 6 to 9.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Symbols, Low Severity 1

	Change	Effect
1	Type of 1st parameter rktparlist has been changed from rd_kafka_topic_partition_list_t* to rd_kafka_topic_partition_list_t const*.	Replacement of parameter data type may indicate a change in its semantic meaning.

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