  • Version 2.1.2 uses 4 additional Kinesis API's
    WARNING: These additional API's may require updating any explicit IAM policies

  While the original shutdown method will continue to work it's recommended to upgrade to the newer interface.
  • The shutdown has been replaced by leaseLost and shardEnded.
  • Added the leaseLost method which is invoked when a lease is lost.
    leaseLost replaces shutdown where shutdownInput.reason was ZOMBIE.
  • Added the shardEnded method which is invoked when all records from a split or merge have been processed.
    shardEnded replaces shutdown where shutdownInput.reason was TERMINATE.
• Updated the AWS Java SDK version to 2.4.0
