Conflicting mappings

Hi
We use Elastic 2.1.1 on Windows server 2012 R2

And we faced with mappings conflict problem described in "Conflicting doc values in mappings causes shard initialization failures" - https://github.com/elastic/elasticsearch/issues/16563

There said that it will be fixed in 2.3.0 release - when will be 2.3.0 Elastic release?

2.3 will probably be out next month.
