The change-log for HTC One update is no different from the dual-SIM version. HTC One users can expect to see Android version bump to 4.2.2, launcher bar enhancements, lock-screen widgets, home button options, new quick settings panel in notification shade, and gallery/ camera app improvements. The update will also bring new Zoe file format, and video highlights to the phone.
Like all other HTC updates, this one also is available over-the-air. HTC will notify you once the update reaches your smartphone, however you can also try to trigger it manually by going to Settings << About Phone << Software update.
If you have already got the update, do let know about the experience in comments.
