Hangouts 4.0 has not been around all too long, but today, Google is slowly starting to roll out Hangouts 5.0 for all through Google Play. The overall feel of the 5.0 update should be very similar to 4.0, although, Google has likely gone through and squashed a ton of little bugs and made the experience on Hangouts smoother.
Once we have played with the update for a bit, we will update this post with what you can expect to see once the update hits your device.
The Google Play link to Hangouts has been placed below, but for those here who are not patient, you can sideload the apk by downloading it from here.
Has the update hit your device yet?
