Since Nokia announced its switch to Windows Phone 7, people have been worried about the future of Qt. Well, it turns out Nokia is still going full steam ahead with Qt, since it has just announced the plans for Qt 5. Some major changes are afoot code and functionality-wise, but the biggest change is that Qt 5 will be developed out in the open from day one (unlike Qt 4). There will be no distinction between a Nokia developer or third party developer.
自诺基亚宣布转向WinPhone 7开始，人们一直担心Qt的未来。看来，诺基亚仍将对Qt全力以赴；刚刚，诺基亚宣布了其Qt 5计划。部分主要变更包括即将到来的代码和功能方面更新，但最大的改变在于，Qt 5将从第一天起就采取开放式开发模式（不同于Qt 4）。自此，诺基亚开发者和第三方开发者将别无鸿沟可言。

Lars Knoll announced the changes, as well as the intended goals and scope of Qt 5, on Qt Labs. There are four goals for Qt 5, and according to Knoll, to achieve these goals, it is needed to break binary compatibility; source compatibility will be maintained 'for the majority of cases'. Knoll promises the transition will be far less painful than the transition from Qt 3 to Qt 4. In any case, these are the four goals:
在Qt实验室，Lars Knoll 在传达Qt 5目标与范围的同时，宣布了这一变更。据Knoll所言，Qt 5有四大目标；要达成这些目标，需要破除二进制兼容性；‘主要套件（cases）’的源码兼容性将被维护。Knoll承诺该次转变将比从Qt 3 转至 Qt 4的转变要轻松得多。任何上下文中，都有以下四点目标：

Make better use of the GPU, allowing you to create smooth (and accelerated) graphics performance even with limited resources
●更充分利用GPU资源，允许你在即使资源十分有限的情况下创建平滑（和加速）的图形效果

Making your creation of advanced applications and UIs easier and faster (with QML and Javascript)
●（协同QML 和 Javascript，）让你创造高级应用与UI的过程更加简单快捷

Make apps connected to the web be as powerful as possible, i.e. to embed and power up web content and services into any Qt app
●使连接到Web的应用尽可能地强大，比如将Web内容和服务嵌入并运行于任何Qt应用之中

Reduce the complexity and amount of code required to maintain and implement a port.
●减少维护和实现端口的复杂度和代码量

The focus will be on X11/Wayland on Linux, Windows, and Mac; other platforms will be on thebackburner from within Nokia. "The goal of the Qt 5 project is to offer the best possible functionality on each platform, implying that Qt will begin to offer more differentiated functionality on some OS’s, while still offering efficient re-use for the absolute majority of the code across platforms," Knoll adds.
主要聚焦平台将会是Linux上的X11/Wayland， Windows，以及 Mac；其他平台诺基亚将视其为后期支持平台。“Qt 5项目的目标是为各大平台提供可能的最佳功能；这意味着Qt将开始为某些操作系统提供更加个性化的功能，同时仍旧支持绝大多数代码的跨平台高效重用，” Knoll补充道。

The remainder platforms currently supported by Qt will have to be added to Qt 5 by the community, which ought to be easier now since Qt is switching to open governance mode. "Qt 4 was mainly developed in-house in Trolltech and Nokia and the results were published to the developer community," Knoll writes, "Qt 5 we plan to develop in the open, as an open source project from the very start. There will not be any differences between developers working on Qt from inside Nokia or contributors from the outside."
其他当前由Qt支持的平台不得不由社区加入Qt 5；由于现在Qt已经转向开放管理模式，这应该会容易些。“Qt 4主要是由Trolltech 和 Nokia关上门来开发的，只是将结果公布在开发者社区，” Knoll写道，“Qt 5作为一个从一开始就开源的项目，我们计划在开放中开发。诺基亚内部致力于Qt的开发者和外部贡献者之间将不再有任何区别。”

The plan is to have a beta release somewhere at the end of 2011, with the final release hitting somewhere in 2012.
据计划，诺基亚在2011年年末将发布一个beta发行；最终发行将是在2012年。
