* MultiLangDaemon: Make shutdown grace configurable (#204)
Allow configuring the amount of time that the graceful shutdown process will wait for the client to complete its shutdown.
* Release 1.8.2 of the Amazon Kinesis Client for Java (#218)
* 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.
Should the checkpoint fail the attempted sequence number is provided in the InitializationInput#getPendingCheckpointSequenceNumber otherwise the value will be null.
* PR #188
* Support timeouts, and retry for GetRecords calls.
Applications can now set timeouts for GetRecord calls to Kinesis. As part of setting the timeout, the application must also provide a thread pool size for concurrent requests.
* PR #214
* Notification when the lease table is throttled
When writes, or reads, to the lease table are throttled a warning will be emitted. If you're seeing this warning you should increase the IOPs for your lease table to prevent processing delays.
* PR #212
* Support configuring the graceful shutdown timeout for MultiLang Clients
This adds support for setting the timeout that the Java process will wait for the MutliLang client to complete graceful shutdown. The timeout can be configured by adding shutdownGraceMillis to the properties file set to the number of milliseconds to wait.

* Calling shutdown on the RetrievalStrategy (#222)
Fixes a bug where the retriever wasn't being shutdown when a record processor was being shutdown.
* 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.

Support timeouts for calls to the MultiLang Daemon
This adds support for setting a timeout when dispatching records to
the client record processor. If the record processor doesn't respond
within the timeout the parent Java process will be terminated. This
is a temporary fix to handle cases where the KCL becomes blocked
while waiting for a client record processor.
The timeout for the this can be set by adding
`timeoutInSeconds = <timeout value>`.
The default for this is no timeout.
Setting this can cause the KCL to exit suddenly, before using this
ensure that you have an automated restart for your application

MultiLangDaemon Feature Updates
The MultiLangDaemon has been upgraded to use the v2 interfaces, which allows access to enhanced checkpointing, and more information during record processor initialization. The MultiLangDaemon clients must be updated before they can take advantage of these new features.
