Let me know if you'd like any assistance updating the snap and which release is appropriate for "stable" release.
Last stable release was NOV 2018, snap version: 383. Latest revision in "edge" which pulls from Git repo is 1422. These numbers do NOT match what the actual software version is; snaps use versions based on "builds".
I can submit a PR but releasing a new "stable" version is pretty easy, depending on what you consider stable.
@allmightyspiff and I have collaborated in the past as I built the original snap when working at SoftLayer.
