Do you have plan new release for elasticsearch-v5.2x , v5.3x v5.4x

HI. 
i wonder if you have a plan for new release(for elasticsearch-v5.2x , v5.3x v5.4x)
i have tried to modify elasticsearch-http-user-auth for elasticsearch-v5.3.1 .
but it is difficult for me. there are many compile error. There are many changes to elasticsearch API (remove RestFilter, RestFilterChain, change xContent.createParser..etc..  )
