昨日Opera官方中文社区发布了Opera 10.70 snapshot build 9071，并声称这是这是最后一版 10.70，Opera 11 将很快到来。

且14日正式宣布Opera 11 将开始支持扩展，且Opera 11 基于 Opera 10.70 开发，Opera 10.70 不再会发布正式版。

需要注意的是：Opera 10.70 snapshot build 9071是一个开发版，并不推荐普通用户使用，仅供测试。因为此版本存在着很多已知问题，可能会造成崩溃或者数据丢失，甚至无法正常使用。请勿覆盖之前的版本，并在备份数据后安装使用。

关于扩展的信息相信大家都能百度到，在此，我附上原版英文内容给大家分享哈：

Good news, everybody! Today, at Up North Web, Opera Extensions was confirmed to be a feature of Opera 11.

Extensions in Opera is a way for you to easily add new functionality to your Opera browser experience. Developers can easily create extensions using open standards (HTML5, CSS, JavaScript) and supported APIs.

Extensions will be based on the W3C Widget specifications and this is being considered for an Open Standard effort.

Yes, Opera Extensions will be similar in some ways and we have tried to make it easy to port extensions from certain browsers.

We are committed to open web standards and this is an important part of our strategy, so if you find us deviating from other solutions out there, this might be why.

Some extensions have user interface elements, but not all. An extension can for example add a button next to the Google Search field with a popup menu when you click on it. Other extensions don't have user interfaces at all, but run in the background.

Once you have Opera 11 installed you can click on an extension and a small Install-window will appear. Click 'Install' and you're done. You can also drag and drop an extension onto Opera Desktop if you have an extension stored on your computer.

With the first iteration of Opera Extensions we are focusing on open web standards and 'getting it right'. Our alpha release supports injectable JavaScript, callouts, certain UI items and a basic Tabs and Windows API.

Opera Extensions is not available yet. Once Opera 11 is out, you will be able to fully enjoy and use Opera Extensions.

Once Opera 11 Alpha is out, you will be able to find all the information you need to develop and publish extensions on our developer site Dev Opera.

Opera 11 Alpha will be made available soon at http://www.opera.com/browser/next/.
