Version 1.10.0 (2016-08-02)

Important: As of Sarama 1.10 it is necessary to tell Sarama the version of
Kafka you are running against (via the config.Version value) in order to use
features that may not be compatible with old Kafka versions. If you don't
specify this value it will default to 0.8.2 (the minimum supported), and trying
to use more recent features (like the offset manager) will fail with an error.

Also: The offset-manager's behaviour has been changed to match the upstream
java consumer (see #705 and #713). If you use the offset-manager, please ensure
that you are committing one greater than the last consumed message offset or else
you may end up consuming duplicate messages.

New Features:

• Support for Kafka 0.10
  (#672,
  #678,
  #681, and others).
• Support for configuring the target Kafka version
  (#676).
• Batch producing support in the SyncProducer
  (#677).
• Extend producer mock to allow setting expectations on message contents
  (#667).

Improvements:

• Support nil compressed messages for deleting in compacted topics
  (#634).
• Pre-allocate decoding errors, greatly reducing heap usage and GC time against
  misbehaving brokers (#690).
• Re-use consumer expiry timers, removing one allocation per consumed message
  (#707).

Bug Fixes:

• Actually default the client ID to "sarama" like we say we do
  (#664).
• Fix a rare issue where Client.Leader could return the wrong error
  (#685).
• Fix a possible tight loop in the consumer
  (#693).
• Match upstream's offset-tracking behaviour
  (#705).
• Report UnknownTopicOrPartition errors from the offset manager
  (#706).
• Fix possible negative partition value from the HashPartitioner
  (#709).
