Improvement
- Kafka metrics templates used in document generation should maintain
  order of tags
- Consolidate MockTime implementations between connect and clients
- Fix repeated words words in JavaDoc and comments.
- Cache lastEntry in TimeIndex to avoid unnecessary disk access
- AbstractIndex should cache index file to avoid unnecessary disk
  access during resize()
- Have State Stores Restore Before Initializing Toplogy
- SSLTransportLayer should keep reading from socket until either the
  buffer is full or the socket has no more data
- Improve KTable Source state store auto-generated names

Bug
- QueryableStateIntegrationTest.concurrentAccess is failing
  occasionally in jenkins builds
- KafkaProducer is not joining its IO thread properly
- Kafka connect: error with special characters in connector name
- Streams metrics tagged incorrectly
- ClassCastException in BigQuery connector
- ClientQuotaManager threads prevent shutdown when encountering an
  error loading logs
- Streams configuration requires consumer. and producer. in order to

  character

- RecordQueue.clear() does not clear MinTimestampTracker's maintained
  list
- Selector memory leak with high likelihood of OOM in case of down
  conversion
- GlobalKTable never finishes restoring when consuming transactional
  messages
- IllegalArgumentException if 1.0.0 is used for
  inter.broker.protocol.version or log.message.format.version
- Using standby replicas with an in memory state store causes Streams
  to crash
- Issues with protocol version when applying a rolling upgrade to
  1.0.0
- A metric named 'XX' already exists, can't register another one.
- Flaky Unit test:
  KStreamKTableJoinIntegrationTest.shouldCountClicksPerRegionWithNonZeroByteCache
- AbstractCoordinator not clearly handles NULL Exception
- Request logging throws exception if acks=0
- KTable state restore fails after rebalance
- Make loadClass thread-safe for class loaders of Connect plugins
- Inconsistent protocol type for empty consumer groups
- Broken symlink interrupts scanning the plugin path
- NetworkClient should not return internal failed api version
  responses from poll

  disconnects

Test
- KafkaStreamsTest fails in trunk
- SelectorTest may fail with ConcurrentModificationException
