Preparing Polaris 1.7.0 release

[Jean-Baptiste Onofré]

Hi folks,

To maintain our "almost" monthly release cadence, I propose to start
preparing 1.7.0 release.

I'm volunteering for this release. I propose cutting the release next
week to finalize 1.7.0 out of the last week of July.

Thoughts?

Regards
JB
