The title-as-submitted ("Underscore.js author breaks 100s of modules because of a disliking of semver") is unnecessarily personalizing and editorializing. I'd suggest a title of just the facts: "Underscore.js 1.7.0 breaks modules by rejecting semantic versioning". (The native title, "Fix the versioning", contains insufficient detail to convey either the important warning-to-Underscore-users nor reflect the issues discussed.) This issue highlights an interesting philosophical split. I suspect the same minimalist, intentional aesthetic that has made Ashkenas's projects so beloved equally drives his dislike of version-inflation, whatever its convenience is to downstream systems on autopilot.
