Message From Chrome

I'm gettihng a messge in the addons that x-notifier will soon be unavailable for Chrome. Is this something Chrome is doing, or are you not continuing it anymore?
It will be a shame to lose it because it has been the mail app I have used in multiple browsers for 11 years, and I'd miss it.
Thanks for the work you've done on it all this time, and I hope i can keep using it.
Cheers
