­　　Chrome 61 正式版今天發布，并增加了很多開發者相關的功能。在 Mac、Windows 和 Linux 系統中，Chrome 61 開始支持 WebUSB API，以及 PaymentRequest API。高級網絡平臺 API 支持大多數硬件外設，如鍵盤、鼠標、打印機和游戲手柄。為了使用教育、科學或工業等專用 USB 外設，用戶必須使用系統級權限查找和安裝可能不安全的驅動程序和軟件。

­　　Chrome現在支持 WebUSB API，在用戶同意的情況下允許網絡應用與外設通信。這可實現上述設備提供的所有功能，同時仍可保證網絡的安全。

­　　PaymentRequest API 可以提供安全、無縫的跨平臺結賬體驗。在 Chrome 61 中，瀏覽器還支持網絡信息 API，這意味著網站可以訪問設備信息，比如設備內存 API 可以檢測內存占有，以優化網頁應用。

­　　在 Android 版 Chrome 61 中，新增加了全新的 Web Share API 網絡分享功能，瀏覽器可以激活 Android 原生分享功能。

­　　Chrome 61.0.3163.79 contains a number of fixes and improvements -- a list of changes is available in the log. Watch out for upcoming Chrome and Chromium blog posts about new features and big efforts delivered in 61.

­　　Security Fixes and Rewards

­　　Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed.

­　　This update includes 22 security fixes. Below, we highlight fixes that were contributed by external researchers. Please see the Chrome Security Page for more information.
