Vinod, If 2.7.0 is "not-yet-ready", then we should not be bumping 1.2 to 2.7.0. But, we should be okay to bump master(1.3) up to 2.7.0 so that we start general-purpose testing against that.
Please go ahead and create a jira for that, and we should be able to bump up trunk to go against that. Thanks, -Sushanth
