Release 1.8.3 of the Amazon Kinesis Client for Java (#224)

* Call shutdown on the retriever when the record processor is being shutdown
  This fixes a bug that could leak threads if using the
  AsynchronousGetRecordsRetrievalStrategy is being used.
  The asynchronous retriever is only used when
  KinesisClientLibConfiguration#retryGetRecordsInSeconds, and
  KinesisClientLibConfiguration#maxGetRecordsThreadPool are set.

 To make it easier for developers to write record processors in other languages, we have implemented a Java based daemon, called MultiLangDaemon that does all the heavy lifting. Our approach has the daemon spawn a sub-process, which in turn runs the record processor, which can be written in any language. The MultiLangDaemon process and the record processor sub-process communicate with each other over [STDIN and STDOUT using a defined protocol][multi-lang-protocol]. There will be a one to one correspondence amongst record processors, child processes, and shards. For Python developers specifically, we have abstracted these implementation details away and [expose an interface][kclpy] that enables you to focus on writing record processing logic in Python. This approach enables KCL to be language agnostic, while providing identical features and similar parallel processing model across all languages.
 
 ## Release Notes
+### Release 1.8.3 (September 22, 2017)
+* Call shutdown on the retriever when the record processor is being shutdown  
+  This fixes a bug that could leak threads if using the [`AsynchronousGetRecordsRetrievalStrategy`](https://github.com/awslabs/amazon-kinesis-client/blob/9a82b6bd05b3c9c5f8581af007141fa6d5f0fc4e/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/AsynchronousGetRecordsRetrievalStrategy.java#L42) is being used.  
+  The asynchronous retriever is only used when [`KinesisClientLibConfiguration#retryGetRecordsInSeconds`](https://github.com/awslabs/amazon-kinesis-client/blob/01d2688bc6e68fd3fe5cb698cb65299d67ac930d/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/KinesisClientLibConfiguration.java#L227), and [`KinesisClientLibConfiguration#maxGetRecordsThreadPool`](https://github.com/awslabs/amazon-kinesis-client/blob/01d2688bc6e68fd3fe5cb698cb65299d67ac930d/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/KinesisClientLibConfiguration.java#L230) are set.
+  * [PR #222](https://github.com/awslabs/amazon-kinesis-client/pull/222)
+
 ### Release 1.8.2 (September 20, 2017)
 * Add support for two phase checkpoints  
   Applications can now set a pending checkpoint, before completing the checkpoint operation. Once the application has completed its checkpoint steps, the final checkpoint will clear the pending checkpoint.
