v1.0.0

1.0.0 is a major update of the API, introducing many new features and enhancements.
Note: The 1.0 API is not compatible with earlier versions of the library.

Feature highlights:

• Inherits all of the new features in librdkafka v1.0.0
• General improvements to client classes:
  • Strongly typed configuration.
  • Construction is via builder classes:
    • Allows/enforces that event handlers are specified at construction time.
    • More extensible.
  • Header support.
  • New Message class abstraction and related changes.
  • Consistency in error reporting across library (via exceptions).
  • Support for fatal errors.
• Added AdminClient:
  • CreateTopics, DeleteTopics, CreatePartitions, AlterConfigs, and DescribeConfigs methods.
  • Moved ListGroups and GetMetadata methods from the Producer and Consumer classes to AdminClient.
• Producer specific improvements:
  • New serialization interface:
    • Non-blocking support for async serializers.
    • Very flexible:
      • e.g. can be easily extended to support header serialization.
  • Capability to specify custom timestamps when producing messages.
  • Message persistence status support.
  • Renamed ProduceAsync variants with a callback to Produce.
• Consumer improvements:
  • A new rebalance API.
  • New deserialization API analogous to the new serialization API.
