­　　Chrome 61 正式版今天發(fā)布，并增加了很多開(kāi)發(fā)者相關(guān)的功能。在 Mac、Windows 和 Linux 系統(tǒng)中，Chrome 61 開(kāi)始支持 WebUSB API，以及 PaymentRequest API。高級(jí)網(wǎng)絡(luò)平臺(tái) API 支持大多數(shù)硬件外設(shè)，如鍵盤(pán)、鼠標(biāo)、打印機(jī)和游戲手柄。為了使用教育、科學(xué)或工業(yè)等專(zhuān)用 USB 外設(shè)，用戶(hù)必須使用系統(tǒng)級(jí)權(quán)限查找和安裝可能不安全的驅(qū)動(dòng)程序和軟件。

­　　Chrome現(xiàn)在支持 WebUSB API，在用戶(hù)同意的情況下允許網(wǎng)絡(luò)應(yīng)用與外設(shè)通信。這可實(shí)現(xiàn)上述設(shè)備提供的所有功能，同時(shí)仍可保證網(wǎng)絡(luò)的安全。

­　　PaymentRequest API 可以提供安全、無(wú)縫的跨平臺(tái)結(jié)賬體驗(yàn)。在 Chrome 61 中，瀏覽器還支持網(wǎng)絡(luò)信息 API，這意味著網(wǎng)站可以訪問(wèn)設(shè)備信息，比如設(shè)備內(nèi)存 API 可以檢測(cè)內(nèi)存占有，以?xún)?yōu)化網(wǎng)頁(yè)應(yīng)用。

­　　在 Android 版 Chrome 61 中，新增加了全新的 Web Share API 網(wǎng)絡(luò)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
