Just like on mobile, Android TV users turn to the Play Store to install new apps. An update has rolled out that bumps the software up to version 5.4.12. The most immediate difference is a tweaked look, as the interface now sports larger titles.
On the functionality front, there's now an Update All button. Presumably it bumps all of your apps up to the latest versions, just as the Play Store does on smartphones and tablets.
The amount of content hasn't gone up, which remains Android TV's greatest issue. The number of action games, for example, remains at a lowly 35.
But that's not the latest version's fault. If you don't already have the update, you can download it below.
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
