How to upgrade vega lite to v3

I could not find any link to update vega lite version2 to version 3 in kibana.
I am using kibana 6.3.2 and my vega version is 2.
I want to upgrade to v3 for creating interactive graphs and Selection Predicate
My ELK stack is running in ubuntu 18.04

Thanks
Joe

I would suggest opening an issue in the Kibana Github repo requesting support for vega lite v3.
