# Changelog # Changelog
### Release 2.0.3 (October 8, 2018)
[Milestone #23](https://github.com/awslabs/amazon-kinesis-client/milestone/23)
* Fixed an issue where the `KinesisAsyncClient` could be misconfigured to use HTTP 1.1.
Using HTTP 1.1 with `SubscribeToShard` is unsupported, and could cause misdelivery of records to the record processor.
* [Issue #391](https://github.com/awslabs/amazon-kinesis-client/issues/391)
* [PR #434](https://github.com/awslabs/amazon-kinesis-client/pull/434)
* [PR #433](https://github.com/awslabs/amazon-kinesis-client/pull/433)
* Lower the severity of `ReadTimeout` exceptions.
`ReadTimeout` exceptions can occur if the client is unable to request data from Kinesis for more than client timeout, which defaults to 30 seconds. This can occur if the record processor blocks for more than the timeout period. `ReadTimeout` could also occur as part of [Issue #391](https://github.com/awslabs/amazon-kinesis-client/issues/391).
* [Issue #399](https://github.com/awslabs/amazon-kinesis-client/issues/399)
* [PR #403](https://github.com/awslabs/amazon-kinesis-client/pull/403)
* Added a callback that allows applications to take actions after DynamoDB table creation.
Applications can now install a callback that is called after creating the DynamoDB table by implementing `TableCreatorCallback`.
* [PR #413](https://github.com/awslabs/amazon-kinesis-client/pull/413)
* Updated the guava dependency to 26.0-jre.
* [PR #420](https://github.com/awslabs/amazon-kinesis-client/pull/420)
* [Issue #416](https://github.com/awslabs/amazon-kinesis-client/issues/416)
* Added some additional debug logging around the initialization of the `FanOutRecordsPublisher`.
* [PR #398](https://github.com/awslabs/amazon-kinesis-client/pull/398)
* Upgraded AWS SDK version to 2.0.6
* [PR #434](https://github.com/awslabs/amazon-kinesis-client/pull/434)
### Release 2.0.2 (September 4, 2018) ### Release 2.0.2 (September 4, 2018)
[Milestone #22](https://github.com/awslabs/amazon-kinesis-client/milestone/22) [Milestone #22](https://github.com/awslabs/amazon-kinesis-client/milestone/22)

### Recommended Upgrade for All Users of the 2.x Amazon Kinesis Client
**:warning: It's highly recommended for users of version 2.0 of the Amazon Kinesis Client to upgrade to version 2.0.3 or later. A [bug has been](https://github.com/awslabs/amazon-kinesis-client/issues/391) identified in versions prior to 2.0.3 that could cause records to be delivered to the wrong record processor.**
**:information_source: Amazon Kinesis Client versions 1.x are not impacted.**
Please open an issue if you have any questions.

[Milestone #22](https://github.com/awslabs/amazon-kinesis-client/milestone/22) [Milestone #23](https://github.com/awslabs/amazon-kinesis-client/milestone/23)
* Fixed an issue where the a warning would be logged every second if `logWarningForTaskAfterMillis` was set. * Fixed an issue where the `KinesisAsyncClient` could be misconfigured to use HTTP 1.1.
The logging for last time of data arrival now respects the value of `logWarningForTaskAfterMillis`. Using HTTP 1.1 with `SubscribeToShard` is unsupported, and could cause misdelivery of records to the record processor.

* [Issue #381](https://github.com/awslabs/amazon-kinesis-client/issues/381) * [PR #434](https://github.com/awslabs/amazon-kinesis-client/pull/434)
* Moved creation of `WorkerStateChangedListener` and `GracefulShutdownCoordinator` to the `CoordinatorConfig`. * [PR #433](https://github.com/awslabs/amazon-kinesis-client/pull/433)
Originally the `WorkerStateChangedListener` and `GracefulShutdownCoordinator` were created by methods on the `SchedulerCoordinatorFactory`, but they should have been configuration options. * Lower the severity of `ReadTimeout` exceptions.
The original methods have been deprecated, and may be removed at a later date. `ReadTimeout` exceptions can occur if the client is unable to request data from Kinesis for more than client timeout, which defaults to 30 seconds. This can occur if the record processor blocks for more than the timeout period. `ReadTimeout` could also occur as part of [Issue #391](https://github.com/awslabs/amazon-kinesis-client/issues/391).

* [PR #388](https://github.com/awslabs/amazon-kinesis-client/pull/388) * [PR #403](https://github.com/awslabs/amazon-kinesis-client/pull/403)
* Removed dependency on Apache Commons Lang 2.6. * Added a callback that allows applications to take actions after DynamoDB table creation.
The dependency on Apache Commons Lang 2.6 has removed, and all usages updated to use Apache Commons Lang 3.7. Applications can now install a callback that is called after creating the DynamoDB table by implementing `TableCreatorCallback`.

* [Issue #370](https://github.com/awslabs/amazon-kinesis-client/issues/370) * Updated the guava dependency to 26.0-jre.

* [PR #387](https://github.com/awslabs/amazon-kinesis-client/pull/387) * [Issue #416](https://github.com/awslabs/amazon-kinesis-client/issues/416)
* Added method `onAllInitializationAttemptsFailed(Throwable)` to `WorkerStateChangedListener` to report when all initialization attempts have failed. * Added some additional debug logging around the initialization of the `FanOutRecordsPublisher`.
This method is a default method, and it isn't require to implement the method. This method is only called after all attempts to initialize the `Scheduler` have failed. * [PR #398](https://github.com/awslabs/amazon-kinesis-client/pull/398)
* [PR #369](https://github.com/awslabs/amazon-kinesis-client/pull/369) * Upgraded AWS SDK version to 2.0.6
