• Feature - Aws::CloudWatchLogs - Added support for destinations. You can now
  use destinations to subscribe to cross-account real-time feed of log events
  from CloudWatch Logs and have it delivered to an Amazon Kinesis stream for
  custom processing, analysis, or loading to other systems.

• Feature - Aws::S3 - Added support for the new long tail storage class and the new
  storage class headers in the GET and HEAD Object responses.

• Feature - Aws::S3 - Added support for the new object delete notification events.

• Issue - Aws::Glacier - Aws::Glacier::Account#vaults was not populating the account
  in the call to list vaults.

• Issue - Aws::EC2 - Resolved a regression with serializing Aws::Structure types in
  Aws::EC2::Client requests. The Aws::Query::EC2ParamBuilder class is responsible
  for testing protocol specific implementations but it tests with input that is loaded
  from a JSON document into a vanilla Ruby hash which does not trigger this behavior.

  The other protocol builder classes have full unit test suites, while the EC2 param
  builder did not. A test case has been added to cover this regression.

  See related GitHub issue #881.

• Feature - KMS Client-Side-Encryption - Added support to Aws::S3::Encryption::Client for using AWS Key Management Service (KMS) to manage master encryption keys.

  s3_enc = Aws::S3::Encryption::Client.new(kms_key_id: 'kms-key-id')
  s3_enc.put_object(bucket:'aws-sdk', key:'secret', body:'data')
  s3_enc.get_object(bucket:'aws-sdk', key:'secret').body.read
  #=> 'data'

  This implementation is compatible with objects written by the AWS SDK for Java
  encryption client.
