一直以来 Google 都会每个月为 Pixel 装置推出软件更新，当中会有安全更新, Bug Fix 修正, 新功能改进等等，就是在每个月的首个星期一推送。
最新 Google 就公布不再以首个星期一为目标。Pixel 用家仍会每个月收到更新推送，但就不一定是首个星期一，而是当 Google 完成所需测试后，就会立即推送至 Pixel 装置。
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.
