 # scalatest-embedded-kafka
 A library that provides an in-memory Kafka broker to run your ScalaTest specs against. It uses Kafka 0.10.1.0 and ZooKeeper 3.4.9.
-            
-For Kafka 0.10.0.x support, override `org.apache.kafka % kafka` dependency with older version:
-
-    libraryDependencies += "org.apache.kafka" % "kafka" % "0.10.0.1" % test
-    dependencyOverrides += "org.apache.kafka" % "kafka" % "0.10.0.1"
-        
-This override is required because Kafka Broker 0.10.1.0 doesn't support older clients.
 
 The version supporting Kafka 0.8.x can be found [here](https://github.com/manub/scalatest-embedded-kafka/tree/kafka-0.8) - *this is no longer actively supported, although I'll be happy to accept PRs and produce releases.*
