The various insider channel (Beta, Dev, & Canary) versions of Edge update themselves. Canary is nightly, Dev is weekly, and Beta approximately every six weeks.
I do not know if the updates follow a phased roll-out schedule or simply go to all users of a given channel at the same time.

Most of the change we think we see in life is due to truths being in and out of favor.
