[Opera 釋出] Next 12.00Alpha #1301 不要追蹤與 XHR
這幾天 DT 又開始了瘋狂趕工的狀態了，一連好幾發的 snapshot 還真是讓人有點應接不暇啊。雖然 DT 使出了「連續技」，但真正把我打動是這篇要說的 snapshot。廢話不多，來看看原文（有需要的話，還有我的三流翻譯）。
Core update with Do Not Track, and mail and theme fixes
由 Haavard. 2012年2月10日星期五下午7:19:41
As you can see from the changelog, this build introduces quite a few fixes, changes and improvements. Since there's a lot of it, I'll highlight a few important things below.
This Wahoo builds adds support for Do Not Track, which allows browser users to opt out of being tracked on the web. It is currently disabled by default, but can be enabled by enabling the following option in Opera's Preferences dialog: "Preferences > Advanced > Security > Ask websites not to track me"
t7yang 註：點這個連結也可以快速切換 DNT 開關。
Note that this will only work if the site actually honors the request. Few sites currently do, and the effect of DNT will have to be evaluated to see if it is a viable solution in the long run.
SSL performance（SSL 效能）
This build also introduces a first round of optimizations for faster SSL handling (CORE-41667):（ 這次的更新也推出了第一階段對加速 SSL 處理（CORE-41667）的最佳化： ）
- TCP optimization to eliminate roundtrips
- Improved session negotiation to save on waiting times
- Improved connection handling which improves both HTTP and HTTPS connections
- Quicker closing of connections allows for new connections at an earlier stage
- Parallelizing OCSP/CRL uses half as much time to do revocation checking
- Strict transport security improves security and will also improve speed when servers start using this feature
As an example, the first load at skandiabanken.no was reduced by one second or more. With 10 subsequent page loads, the time to open the page was almost cut in half in total.
With CORE-41784 (XMLHttpRequest Level 2 upload and progress events), we completed our support for progress events in XMLHttpRequest, for upload, download, and timeout update. This will improve the upload experience on Google services (no more Flash uploaders on YouTube and Gmail), and more sites are to follow.
t7yang 註：讀者可以試試用這版去開 GMail，就可以感覺到有別於以往的飛快反應速度，真的很過癮。
There are numerous other improvements, including Core, mail and theme fixes. Take a look at the changelog for more information.

最後要提的是，面板的切換條已經修好，還有比這個更開心的事嗎？哈哈哈…不過話說回來這版開 GMail 真的是爽度十足。另外有網友爆料說接下來 DT 會開始開發對 HTML5 拖曳上傳的支援，希望進度可以快一點 XD
