Deprecate old branches and close their issues (< 7.x) and start with a fresh 10.x branch

+1

There's lots of history as you say, but these older versions have not been actively maintained for a long time. Go ahead and deprecate and clean up as you've described.

Thanks @jeremy! We'll do so!

I've closed all issues that were left for 6.x as outdated now. Only 21 open issues left, while there were over 350 of the old ones. :P

Thank you very very much @lrwebks for the cleanup!

10.x is also set up as default branch now. Supported branches were set correctly already.

Automatically closed - issue fixed for 2 weeks with no activity.
