Developer Edition was a channel and not a version of Firefox. It used to be Release < Beta (b#) < Aurora (a2) (developers Edition) < Nightly (a1) and now it is Release < Beta (b#) < Nightly (a1)

The current Developer Edition is actually 58.0b4 : https://archive.mozilla.org/pub/devedition/releases/58.0b4/

It is basically Beta builds with Developer Edition features. The Beta builds can have on average nine to fourteen builds for a version on channel.
