You won’t see mention of it in the release notes, but the latest version of Google+ for Android now has a Chromecast button. Android Police spotted the Chromecast icon and says you can cast a main Google+ stream to a television over Wi-Fi using Google’s $35 Chromecast dongle. Using your Android phone or tablet, you can scroll through your feed — just the “Everything” feed at the moment — or let the app automatically scroll as new content becomes available. We’ve seen situations in the past where the Chromecast icon appeared and disappeared, so it’s possible Google is just testing the feature for now.
