During our finalization of the compliance request we discovered an issue that needed to be resolved with the standards alliance. They are currently helping us resolve it right now and hopefully it will be done in the next couple of days. This does mean that we will release a firmware 1.1.5r2 to all users and we might fix a minor bug in this release at the same time. I know the process is slow and I wish we could speed things up, but not rushing helps us reduce the risk of making a mistake. I apologize that the email was sent out early, but everything in it still applies it is just taking a little longer than what we thought.
@thekiefs at this time we are not releasing the firmware broadly to Google Home users. The main reason is that Google Home does not provide users a way to choose which devices get updated and when. This could result in middle of the night updates, updates while on vacation, etc. Since the update can unintentionally change settings, we decided to push the update to Google Home users upon request. PM me if you would like to have this option and I will gladly help you out.
