On January 27, Apple today released the tvOS 15.3 (19K547) system update for Apple TV HD/4K, the third major update to the tvOS 15 operating system, which was first introduced in September 2021, and tvOS 15.3 was released more than a month after the launch of tvOS 15.2.
tvOS 15.3 can enter the system through the Settings app > Software Update, OTA updates on Apple TV, Apple TV with automatic software update enabled will automatically upgrade to tvOS 15.3.
Apple's tvOS updates are generally smaller in scale, with a focus on bug fixes, performance updates, and minor tweaks. No new features have been discovered in tvOS 15.3 at this time, so it's unclear what will be included in the update.
