We’ve received some good feedback from the community on the first release candidate of version 1.7.0, and have made some improvements that we wanted to share with you.  This second release candidate is more stable and features some code-tightening as well (MIME types are now case insensitive, a limited SRS list persists again, and more.)  This is the most stable release yet of the new 1.7.0 branch and we encourage you to try it out.  If all goes according to plan, we should have a final release around the corner.
