Hi @filosganga ,
Made version update changes for Kafka and confluent schema registry, to use some of the features present in confluent schema registry:4.1.1 library. For exp: confluentinc/schema-registry#680 to register different aggregate event types with same topic name.
If you feel this PR add value, could you please review and merge the code changes.

@jadireddi any examples available

@jadireddi I believe that while the schema registry will support multiple types per topic. The confluent serializer doesn't yet do it out of the box? Is it a correct assumption?

sorry for last reply.. Edited.

@filosganga , You are right. With the new feature , registering multiple schema's under same subject, .
the confluent serializer doesn't yet do it out of the box. Above pull request is only for subject naming strategy.

For example :
`val schemaRegistryEndpoint = "http://localhost:8081"

val schemaRegisterProps: Map[String,String] = Map[String,String](
"key.subject.name.strategy" → "io.confluent.kafka.serializers.subject.TopicRecordNameStrategy",
"value.subject.name.strategy" → "io.confluent.kafka.serializers.subject.TopicRecordNameStrategy"
)
val schemaRegistryClientSettings = new SchemaRegistryClientSettings (schemaRegistryEndpoint, com.ovoenergy.kafka.serialization.avro.SchemaRegistryClientSettings.DefaultAuthentication, 12, 4 )

val schemaRegistryClient = JerseySchemaRegistryClient(schemaRegistryClientSettings)

val serializer = avroBinarySchemaIdSerializer[UserCreated](schemaRegistryClient, isKey = false, includesFormatByte = true,
props = schemaRegisterProps)`

Above example schemaRegisterProps takes care of naming strategy. For brief note, kindly refer:
