<li> Starting from Kafka 0.10.0.0, a new client library named <b>Kafka Streams</b> is available for stream processing on data stored in Kafka topics. This new client library only works with 0.10.x and upward versioned brokers due to message format changes mentioned above. For more information please read <a href="#streams_overview">this section</a>.</li>
- <li> If compression with snappy or gzip is enabled, the new producer will use the compression scheme's default buffer size (this is already the case for LZ4) instead of 1 KB in order to improve the compression ratio. Note that the default buffer sizes for snappy, gzip and LZ4 are 0.5 KB, 32 KB and 64KB respectively. For the snappy case, a producer with 5000 partitions will require an additional 155 MB of JVM heap.</li>

<li> The default value of the configuration parameter <code>receive.buffer.bytes</code> is now 64K for the new consumer.</li>
<li> The new consumer now exposes the configuration parameter <code>exclude.internal.topics</code> to restrict internal topics (such as the consumer offsets topic) from accidentally being included in regular expression subscriptions. By default, it is enabled.</li>
<li> The old Scala producer has been deprecated. Users should migrate their code to the Java producer included in the kafka-clients JAR as soon as possible. </li>
