The README claims that 4.x does not support puppet 2.7.x, yet the "policy" is not to merge patches that break 2.7.x. Due to that I'm sure there are a lot of 2.7.x installations out there that have a 4.x version of stdlib installed. That's going to cause a rather rude surprise if some future version of 4.x stops working where a prior minor release was functioning. I'd like to suggest that the documentation be changed to reflect 4.x supporting 2.7.x and that a new major version bump is made when 2.7.x support can in fact be dropped. An alternative solution would be update the README with a note to developers about the kinda/sorta/maybe/fishy/quasi support of 2.7.x.
