Like most small-backing Chromium clones it's usually ~2 months behind on patches (normal and security) and the published source is about ~10 months behind. Being effectively closed for the release version and very small from a development side it does wonky things like redirect your "Google" searches through their servers since they don't have proper search agreements.

I.e. it's basically "an interesting Chromium clone maintained by a couple of folks out of Estonia". If you're cool with that it can be a nifty browser, for many that just makes it to unproven to dump access to their entire online world into.
