v0.18.1 is released before upgrading (which shouldn't take more than a few days)
A bird in the hand is worth two in the bush, and an update that fixes bugs which break basic functionality is worth upgrading for immediately rather than waiting for over-the-rainbow. 2FA alone makes it pretty much not a realistic discussion, honestly.
It's another few days with websockets, broken sorting, a front-page-breaking bug, and no 2FA. Plus the site is even more broken for everybody running the latest version of Jerboa till 0.18.0 gets installed.
