I've already uploaded new build to Chrome Web Store review, so let's leave this one for the next release :)

Hi @martgil, did we get any reports from users about stuck extension after update, like we had for previous release?

[martgil]

Hello Roma, some of our users are already running 8.5.12 and have successfully have a working installation of them thought their methods of getting it is by uninstalling and reinstalling the extension as the automatic update hasn't reached them yet and they can't wait for it to arrive by itself, so they have uninstall and reinstall the app by themselves and have informed us about this through email.

We haven't had any reports received regarding extension being stuck after update yet. I'll be swift in writing here as soon as we recieved any feedback anytime soon.
