* Release 1.9.1 of the Amazon Kinesis Client Library for Java
Updated versions, and added release notes.
* Added note about the update of the AWS Java SDK
* Allow providing a custom IKinesisProxy implementation.
* PR #274
* Checkpointing on a different thread should no longer emit a warning about NullMetricsScope.
* PR #284
* Issue #48
* Upgraded the AWS Java SDK to version 1.11.271
* PR #287
Release 1.8.8
* Fixed issues with leases losses due to `ExpiredIteratorException` in `PrefetchGetRecordsCache` and `AsynchronousFetchingStrategy`.
PrefetchGetRecordsCache will request for a new iterator and start fetching data again.
* PR#263
* Added warning message for long running tasks.
* PR#259
* Handling spurious lease renewal failures gracefully.
Added better handling of DynamoDB failures when updating leases. These failures would occur when a request to DynamoDB appeared to fail, but was actually successful.
* PR#247
* ShutdownTask gets retried if the previous attempt on the ShutdownTask fails.
* PR#267
* Fix for using maxRecords from `KinesisClientLibConfiguration` in `GetRecordsCache` for fetching records.
* PR#264
* Release 1.8.5 of the Amazon Kinesis Client for Java
Release 1.8.5 (September 26, 2017)
* Only advance the shard iterator for the accepted response.
This fixes a race condition in the `KinesisDataFetcher` when it's being used to make asynchronous requests. The shard iterator is now only advanced when the retriever calls `DataFetcherResult#accept()`.
* PR #230
* Issue #231
* 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.
* PR #222
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.
