谷歌瀏覽器Google Chrome正式版迎來v91首個版本發布，詳細版本號為v91.0.4472.77，上一個正式版v90.0.4430.212發佈於5月11日，時隔15天Google又發布了新版Chrome瀏覽器，本次升級主要是更新了安全修復和穩定性改進及用戶體驗。
Chrome v91.0.4472.77 正式版（2021-05-26）
谷歌瀏覽器v91正式版主要更新，支持桌面應用程序對剪貼板進行只讀訪問，該功能將允許用戶使用剪貼板鍵盤快捷鍵，如Ctrl+C和Ctrl+V，將文件附加到電子郵件中，而不是僅僅依靠拖放方法。默認啟用WebTransport和WebAssembly SIMD這兩項實驗性功能。前者是一套全新的協議框架/標準，適合與遠程服務器展開安全的多路傳輸通信。後者則是WebSockets的一個替代方案，並提供了類似UDP的數據報雙向通信API。
谷歌瀏覽器v90正式版主要更新，引入了許多以用戶為中心的功能改進，輔以安全性方面的進一步提升。默認向目標網站鏈接均啟用SSL安全傳輸協議(HTTPS)，全新AV1開源視頻編碼器的技術支持，高清視頻佔用大幅減小。新增窗口重命名功能，可重命名已打開的多個窗口，可記住窗口的配置，遇到崩潰重啟會自動恢復狀態。還有WebXR深度API、啟用了URL協議設置程序、效果疊加層、以及安全性方面的諸多改進，比如為了防範緩解NAT Slipstream 2.0攻擊，而屏蔽封鎖了通過554端口的HTTP/HTTPS/FTP服務器訪問。
谷歌瀏覽器v89正式版主要更新，修復了一個零日漏洞，建議用戶儘快更新。優化了對WebHID、WebNFC和Web Serial等適用於HID設備API的支持，此外NFC和串行設備也被認為可以投入生產使用。還初步為WebRTC添加了對AV1編碼的支持。此外桌面端還帶來了Web Share和Web Share Target支持以及其他增強功能。
