Replacing New Relic plugin with new version in Github

Hi Logstash folks!

New Relic has developed a new version of logstash-output-newrelic, and have replaced the Ruby Gem associated with it. We were hoping to replace the repo in your org with our own, or have that one point to ours. Who should we speak to about the best way to move forward with consolidating these projects?

Links:
Old plugin repo: https://github.com/logstash-plugins/logstash-output-newrelic
New plugin repo: https://github.com/newrelic/logstash-output-plugin
Ruby gem: https://rubygems.org/gems/logstash-output-newrelic

Please let me know how to proceed.

Thanks in advance!
