@aarepuu Multiple eggs is no problem for us, I'd like to get you up to the latest hardware if possible. Please go ahead and email support so we can work out details.
Incidentally, the way I've been releasing firmware baselines is as individual board support packages. So if you wanted to get the v2.1.6 baseline, for example, it's contained in Arduino board package http://update.wickeddevice.com/package_airqualityegg-2.1.6_index.json, for example. The latest source code for any given model, i.e. pre-release, is available on git-hub as well in repositories like: http://github.com/wickeddevice/aqev2fw_no2co_esp.
