voxpupuli/puppet-elasticsearch 6.3.3 on GitHub

Note that this release includes changes to a default value that may affect users that rely on curl or wget to retrieve Elasticsearch package files, as now all certificates are validated by default.
To preserve existing behavior, set $elasticsearch::download_tool_verify_certificates to false.

Fixes

Update puppetlabs-stdlib dependency to < 6.0.0
By default, package files downloaded with tools like wget or curl (i.e., the $elasticsearch::download_tool parameter) now verify certificates by default and a new boolean parameter has been added to indicate whether to ignore certificates ($elasticsearch::download_tool_verify_certificates).
