這個(gè) build 引入了相當(dāng)多的修復(fù)、改變和提升。有幾點(diǎn)尤其值得關(guān)注。例如開始支持 DNT (Do Not Track)。只有網(wǎng)站本身嚴(yán)格自律,DNT 才能幫助保護(hù)用戶隱私,所以 Opera 對(duì) DNT 的實(shí)際意義一直有所保留;SSL 性能;完善對(duì) XHR progress 的支持;和內(nèi)核、M2 郵件客戶端、主題相關(guān)的大量修復(fù)。 如你從更新日志所見,這個(gè) build 引入了相當(dāng)多的修復(fù)、改變和提升。有幾點(diǎn)尤其值得關(guān)注。
隱私
該 build 開始支持 Do Not Track ,它允許瀏覽器使用者選擇在網(wǎng)上不被追蹤。目前該設(shè)置默認(rèn)是關(guān)閉的,可以在首選項(xiàng)對(duì)話框中設(shè)置:首選項(xiàng) > 高級(jí) > 安全性 > Ask websites not to track me"(這個(gè) build 的中文語言包還沒有對(duì)應(yīng)翻譯過來)。
注意,這玩意僅當(dāng)網(wǎng)站確實(shí)尊重此要求的時(shí)候才有用。目前沒幾個(gè)網(wǎng)站這樣做,后續(xù)要評(píng)價(jià) DNT(Do Not Track)的效果,才能判斷長遠(yuǎn)來說它是不是可靠的解決方案(譯者注:這也是 Opera 比其他瀏覽器晚了不少才開始支持 DNT 的原因,只有網(wǎng)站本身嚴(yán)格自律,DNT 才能幫助保護(hù)用戶隱私,所以 Opera 對(duì) DNT 的意義一直有所保留)。
SSL 性能
該 build 開始了加速 SSL 處理的第一輪優(yōu)化 (CORE-41667):
優(yōu)化 TCP 以消除 TCP roundtrip
改進(jìn)會(huì)話協(xié)商以節(jié)省等待的時(shí)間
改進(jìn)連接處理,HTTP 和 HTTPS 連接都會(huì)因此改善
更快地關(guān)閉連接使新連接得以更早開始
用同等的時(shí)間處理 OCSP/CRL 以檢查證書是否吊銷
使用 (HTTP) 嚴(yán)格傳輸安全性 (HSTS) 提升安全性,如果網(wǎng)站服務(wù)器啟用了該特征,訪問速度也會(huì)提高。
例如,第一次載入 skandiabanken.no 可以加快 1 秒甚至更多。加上后續(xù) 10 次頁面載入,相比于優(yōu)化之前,總的加載時(shí)間幾乎減少了一半。
XHR
CORE-41784 (XMLHttpRequest Level 2 上傳和 progress 事件)此內(nèi)核更新使 Opera 得以完整支持 XMLHttpRequest 的 progress 事件,可用于上傳、下載和 timeout update。這可以改善在使用 Google 的服務(wù)時(shí)上傳文件的體驗(yàn)( 在 YouTube 和 Gmail 中上傳文件將不再依賴 Flash ),將來會(huì)有更多網(wǎng)站跟進(jìn)。
更多
改善相當(dāng)多,包括內(nèi)核、M2 (郵件客戶端)和主題(舊稱“皮膚”)的修復(fù)。詳情見更新日志。
