If you're running an HTC One on AT&T (other carrier devices don't apply here) and use the HTC Backup app, you'll want to pick up today's update. It's got fixes for Sense 5.5 (which you should now have along with the Android 4.4.2 update), supports contacts and text messages, you can choose to back up to Google Drive or Dropbox, and you can now sign in with your Google account.

Good additions, all.
