节录重点如下
Storage
We are introducing new ways to reduce the amount of storage space utilized on
your Google TV by reducing app sizes and hibernating background apps.
App Hibernation is a new feature that will automatically force apps to
hibernate when not used for over 30 days (on Android S and above devices). We
also leveraged Android App Bundles for Google TV reducing the size of the
apps by roughly 25%. This frees up space on your device to download even more
apps and to watch your preferred programs without worry.
Best of all, both of these features have already rolled out to your devices
and require no action from you.
我们正在引入新方法，通过减小应用大小和休眠后台应用来减少 Google TV 上使用的存
储空间量。
应用程序休眠是一项新功能，当超过 30 天未使用时（在 Android S 及更高版本的设备
上），它将自动强制应用程序休眠。 我们还利用适用于 Google TV 的 Android App
Bundle 将应用程序的大小减少了大约 25%。 这会释放您设备上的空间，让您可以下载更
多应用程序并安心观看您喜欢的节目。
Performance
We have made updates to both your devices and remotes to eliminate wait time.
We reduced the time it takes to wake up your Google TV, the response time
between your TV and button clicks on your remote, and the amount of time you
see the loading animation when rebooting your device. These improvements are
already rolling out to your devices and will help you get to your content
faster.
我们已对您的设备和遥控器进行了更新，以消除等待时间。 我们减少了唤醒您的
Google TV 所需的时间、您的电视和遥控器上的按钮点击之间的响应时间，以及您在重启
设备时看到加载动画的时间。 这些改进已经在您的设备上推出，将帮助您更快地访问您
的内容。
有 Chromecast with Google TV 的人可以试着按系统更新看看，或许可以减少卡顿感?
