We managed to also pick up a new updated apk for Hangouts today too. Looks like it is a very minor update, only taking it from version 22.214.171.1243199 to 126.96.36.1998356 (at least on the Xperia Z). Doesn’t make it a very big update, but an update nonetheless. According to the PLay Store, this update adds in some more Emoji icons, a little butter to makes things faster and slicker and a bunch of various bug fixes.
As always, if you don’t see it in the Play Store yet then hit up one of the links below to download the APK and get it loaded.
