Elasticsearch graph - 2.3 release

Hi, does anybody know targeted release date of ES 2.3?
Is it still the plan for graph plugin to be part of that release?

Well... https://twitter.com/elastic/status/715213393955676160

Hi @clandestino_bgd_2

The graph plugin was just released!

  • You can find the download page here
  • You can find the reference docs here

And if you have any questions, feedback, etc, we just launched a new section of discuss.elastic.co for Graph-related things here

It seems it is a commercial plugin...
Very disappointing.
