Given that my evaluation version of Student 2015-16 is expiring and Student 2016-17 will be out in May, I am trying to decide which version to upgrade to. Any suggestion on this? I found the new Flattening Surface feature of 2015 useful. Are the new 3D printing features and GUI in 2016 worth the upgrading?
Given that you are a student (regardless is it worth it or not at a design level) I would advise you to get the new version when the old version runs out.
Potential employers will be impressed that you have been actively keeping up to date with the software and training yourself with new releases.
At a business level it's a whole different story and many factors come into play.
