[Opera 釋出] Next 12.00A #1429 最佳化與卡卡問題調整

RC 前夕總是會有一段爆肝的衝刺，看來 12 版 Wahoo 好像真的要出來見客了。當然讓人看了恨得牙癢癢的卡卡問題似乎看到了曙光。

 

Improvements to Performance, Mail, HTML5 Drag'n'drop and more!

As Opera fans I am sure you are aware that we are always working to make our browser even faster. So perhaps you won't be surprised to hear that this snapshot includes some nice performance improvements in software rendering, when run on a processor with SSSE3 available. No doubt you will be keen to try this for yourself but here is a quick graph comparing the last two snapshots on one of our test machines, when running the canvasbench, Retro DOM and Retro Canvas tests. I'm sure you will agree they show some very decent speed improvements!

老鳥們應該都知道我們對速度的追求，所以相信你們對這版著重在改善軟體成像的效能不會感到驚訝（t7：拖到現在才做最佳化還好意思說），當然這必須得在備有 SSSE3 的處理器上才會看到效果。上圖是我們比較近兩個 snapshot 的結果，不信的話你們可以自己試試。比較的項目包含 canvasbench、Retro DOM 和 Retro Canvas 測試。

Next up we have a range of really nice fixes and improvements for our Mail client. Rather than trying to do them all justice I would encourage you to have a good read of the Mail section in the Changelog below. I'm sure you will find plenty of stuff to make you smile. Though perhaps I should highlight the fix for the POP crash on 64-Bit Windows as we know a few of you have been waiting patiently for this!

第二就是我們修正和改善了我們的郵件管理起器。看看我們提供的更新記錄，你就會更了解了。讓一些人引頸企盼的在 64 位元的 Windows 系統地下的當機問題也得到修正了。

We have also done a fair bit of work to improve the Desktop HTML5 Drag and Drop implementation fixing various issues on all three platforms. Again, have a look at the Changelog for more details.

另外，我們還對 HTML5 的拖放實作作了一些改善，當然囊括了三個平台。（t7：Dropbox 真的可以用拖放上傳 開心）

Another highlight for you bug hunters out there is that we now allow you to customize your User-Agent. Whilst we would strongly advise you not to run Opera like this all the time it can be handy to temporarily tweak your User Agent string to match that of another browser. This will let you see if a site is failing to load because we don't fully support it, or simply that the site's developers have intentionally blocked Opera. Enjoy investigating and let us know if you discover anything interesting.

另一個重磅功能就是自訂 User-Agent。但我們強烈建議你不要長時間使用自訂的 User-Agent，偶爾拿來解決瀏覽器因為無法完全相容導致無法載入的問題和騙騙那些故意阻擋 Opera 的不肖企業或公司是 OK 的。嘗試看看，有問題請記得回報。

As always, thanks for testing!

WARNING: This is a development snapshot: It contains the latest changes, but may also have severe known issues, including crashes, and data loss situations. In fact, it may not work at all.

昨天一天兩發的 DT 文已經講明白 RC 已經將近了，但令人開心的絕對不是這個，而是 DT 終於對 Opera 對 Position:Fixed 元素過敏的體質做了一些調養了。根據慣例我會擇最後的一篇來翻譯，無論如何，大家可以試試看，真的有變得比較順了，放心啟用平滑捲動吧（了不起就再關掉而已）！

不過說真的，最佳化後的效果還是很明顯的。最好的標準就是開啟硬體加速後，在快速撥號下切換面板時，快速撥號們都可以很滑溜的「滾到一邊去」。不過硬體加速的最佳化看來還遠遠沒有達到可以「出廠」的標準，而且 DT 大概也覺得這條魚不能再拖下去。所以就棉被一蓋，把硬體加速預設停用後強推 12 正式版，之後再來慢慢修。

起碼我目前用起來是還算滿意啦！不過說真的，1429 我一直無法正常安裝，因為一直當，所以最後我只好用解壓縮的方式更新……

給關心 t7yang 的朋友：

 今天（其實是昨天）終於想不開去申請微網誌了（菸酒生怨念比較重，想要適時宣洩一下），挑了一家看起來最不邪惡的來用。有興趣的話可以加我當好友，雖然我現在還不太會用就對了。http://www.plurk.com/t7yang
