tvOS, the operating system that runs on the fourth-generation Apple TV, is also set to receive some updates this fall alongside iOS, macOS, and watchOS.

tvOS isn't getting as many changes as these other operating systems, but as can be seen in the video below, there are some important new features being added that make it easier to find content and easier to watch live television.

New in tvOS 10 is Siri's ability to search for movies by topic, bringing up content around a theme. Queries like "Show me high school comedies from the 80s" or "Find me movies about dinosaurs" now work. Siri's also gaining the ability to open live channels directly through a Live Tune-In feature that works when you say something like "Watch CBS News" or "Watch ESPN," and Siri can also manage HomeKit accessories.

At WWDC, Apple mentioned that YouTube search is on the way, allowing users to ask Siri to find cute kitten videos or videos of hamsters eating tiny burritos, but that's actually a feature that's going to be available ahead of the fall release of tvOS.

A new Single Sign-On option for pay TV apps is available in tvOS 10, allowing users to sign in once with their cable credentials to access live cable content available through their cable subscription. Apple plans to introduce a new Remote app for iOS devices that mirrors the layout of the Siri remote, and developers are getting a lot of new APIs to build into their apps.

For the first time, games will be able to require a controller, so more complicated controls will be possible, and there are also APIs for recording and live broadcasting, using HomeKit, and accessing iCloud Photo Library photos.

Other new features in tvOS include a dark mode, a Continuity option for easier text input on the iPhone, automatic app downloads, a "Memories" feature in Photos, and a redesigned Apple Music app.

Not all tvOS features are working in the developer beta now, including Single Sign-On, but Apple will likely add functionality as the beta testing process progresses.
