No Validation for required checkboxes
Steps to reproduce with latest master (I don't know if it affects 7.6, too):
1) Install styleguide extension
2) create a new item Styleguide > Form engine - required
3) Go to tab "Select"
if you look at the section "select_4 selectCheckBox, minitems=1, maxitems=2":
1) there is no error message or red outline
2) if you compile all the fields except that one, you can save the item: so, IMO, the validation does not work

The problem here seems now partially solved;
AFAICS the only validation still failing is:
Styleguide > Form engine - required > tab "Select" > "select_5 selectTree, minitems=1, maxitems=3"
There is another problem, which is the absence of text inside the "Review fields with failed validations" popover opened clicking on the "i" icon
