Any packaging system worth using will have support for semver extensions; it pains me that too many systems (including this one) don't appear to.<p>For example, "1.2.3+myfix1" should be valid, and "1.2.3+myfix2" should be considered a later version than "1.2.3" -- and both should pass any dependency declaration against which version 1.2.3 would pass.<p>If anyone can think of other workable solutions that lessen the pain of parallel development and local branching, I'd love to hear them.
