Chinese subtitles embedded in MKV files now display correctly instead of showing empty boxes, even when the subtitle asks for a font your device doesn't have.

CHANNELS Your library as always-on TV channels, with a nostalgic cable-box programme guide. Tune in and join whatever's on, or watch any upcoming programme from the start. Make your own channels by genre, folder and time of day, and they follow you between iPhone, iPad, Mac and Apple TV through iCloud, so channel 3 at 9 PM is the same programme on every screen. MORE SUBTITLE LANGUAGES Chinese (Simplified and Traditional), Japanese and Korean subtitles now display correctly instead of empty boxes.

This update adds an occasional, well-timed rating request after successful playback. It never interrupts playback, casting or Picture in Picture.

• Films and shows with more than one soundtrack now start in English, rather than whichever language the file happened to list first. • Choose your own default in Settings — pick any language and every title follows it. • You can still change the audio track from the player whenever you like. • Subtitles now have a preference of their own, and stay off unless you turn them on.

• A new spotlight at the top of the home screen featuring your latest additions. • Watch a title's trailer from its page. • See the cast of any movie or show, and jump from an actor to everything of theirs in your library. • Lock Screen and Control Center playback controls now work for every file type.

Downloads: keep films and episodes on your device and watch them with no connection to your server. Manage them from the new Downloads tab. Casting: your phone is now a proper remote for Chromecast, with a scrubber, play and pause, 15-second skips, volume and mute. Stopping a cast returns you to exactly where the television got to, and casting is far more reliable, with stalls and missing sound fixed.
