Original PR: - path: performance and stability improvements on all platforms nodejs/node#5123 Fixes: - path: fix normalize for absolutes nodejs/node#5589 - path: fix verbose relative() output nodejs/node#5389 - path: fix path.relative() for prefixes at device root nodejs/node#5490 - path: fix win32 parse() nodejs/node#5484 - path: fix win32 relative() when "to" is a prefix nodejs/node#5456 The number of regressions already found makes me a bit anxious about landing these changes. Personally I would like to see this live on v5.x for as long as possible before we backport to v4.x, if we do at all. A good sign that it is time to backport this will be when we are having trouble landing other unrelated fixes / changes. Until that happens I think it would make the most sense to hold off and keep this issue updated. I've added the `lts-agenda` tag so that we can discuss this at the next meeting
