Google has updated its official iOS YouTube app
to v1.4, making a pair of significant changes. Perhaps most important is the addition of suggestion overlays, which recommend clips to watch next. The feature brings the iOS app closer to par with the desktop website.
Similarly the app now supports closed captioning for live streams, not just fixed-length clips. Other changes are minimal, only fixing stability glitches which sometimes caused the app to crash. YouTube is a free download, and runs on devices supporting iOS 6 or later.
