一直以來 Google 都會每個月為 Pixel 裝置推出軟件更新，當中會有安全更新, Bug Fix 修正, 新功能改進等等，就是在每個月的首個星期一推送。
最新 Google 就公佈不再以首個星期一為目標。Pixel 用家仍會每個月收到更新推送，但就不一定是首個星期一，而是當 Google 完成所需測試後，就會立即推送至 Pixel 裝置。
We also dug into how we can deliver the highest quality, best tested updates to Pixel users on a consistent basis. As part of this effort, our security updates, bug fixes and feature updates won’t roll out on a specific day each month. Instead, we’ll deploy updates as soon as they’ve completed the necessary tests to ensure they improve the experience for all Pixel customers.
