It's just a one-item changelog, but we'll take any improvements we can get
From the outside looking in, it doesn't seem like Google is giving too much time towards improving the Google Voice app or service, but it certainly makes us hopeful when we see an update arrive in the Play Store. Today's update has a single item on the changelog: "Improved the reliability of SMS delivery". Anyone that has used Google Voice for some amount of time knows that things can be a little shaky sending and receiving texts when in low or slow signal areas (and sometimes even in great signal areas), so hopefully this update addresses some of those issues.
As for the future of Google Voice, we can only wonder. In the meantime we know at least some amount of time is being spent over at Google maintaining the app. You can grab a download of this latest version from the Play Store link above.
