This is the second in a series of pre-6.0.0 releases designed to let you test out your application with the features and changes coming in 6.0.0, and to give us feedback about any problems that you encounter.

IMPORTANT: This is an alpha release and is intended for testing purposes only. Indices created in this version will not be compatible with Elasticsearch 6.0.0 GA. Upgrading 6.0.0-alpha2 to any other version is not supported.
