Qt 6.0正式发布了_Qt中国的博客-CSDN博客 https://blog.csdn.net/Qt_China/article/details/111034861

核心库和API

我们为Qt Core做了大量工作，因为它是实现Qt最核心部分的模块，我们做了许多改进。列举几个最重要的例子：

新的属性和绑定系统：该系统将绑定的概念（使QML在Qt5取得了巨大成功）带回到了Qt的核心，并使其可用于C 。
字符串和Unicode：Qt 5时我们朝着使Qt与Unicode完全对齐的方向发展，所以许多工作已经完成。但是，剩下的一些部分已在Qt 6中得到了清理。更多详细信息将很快在另一篇博文中介绍。
QList在Qt 5中经常受到批评，因为它是对存储在其中的大于指针的对象进行堆分配，这给内存分配器带来了很大的压力。在Qt 6中，我们对此进行了更改，并将QList和QVector统一为一个类。有关更多详细信息，请参见我们在Qt 6中有关QList的博客。
QMetaType和QVariant是Qt元对象系统的基础。没有QMetaType，信号和插槽将无法实现，动态调用需要QVariant。 Qt 6中的这两个类几乎完全重写，您可以在此处找到详细信息。

Qt中与图形无关的其他部分也完成了显著的改进。比如完成了Qt Concurrent的大量重写，使得多线程应用程序的开发更加简单。我们对Qt Network也做了大幅整理和改进（具体内容请参考这篇博文）

Qt 6.0 Released https://www.qt.io/blog/qt-6.0-released

Core libraries and APIs

Much work has gone into Qt Core, as it is the module that implements the most central parts of Qt. We've gone through many areas there and made improvements. To name some of the most central ones:

The new property and binding system: This system now brings the concept of bindings that made QML such a huge success in Qt 5 available from C .
Strings and Unicode: With Qt 5, we started aligning Qt fully with Unicode, where we completed a lot of the work, but a few items remained that we now cleaned up for Qt 6. More details will come in a separate blog post later on.
QList has been a class that was often criticized in Qt 5, as it was heap allocating objects stored in there that were larger than a pointer, leading to pressure on heap allocation methods. In Qt 6, we changed this and unified QList and QVector into one class. See our blog post about QList in Qt 6 for details.
QMetaType and QVariant are fundamental to how our Qt’s meta-object system works. Signals and slots would not be possible without QMetaType and QVariant is required for dynamic invocations. Those two classes got an almost complete rewrite with Qt 6, and you can read about the details here.

Other parts of Qt that are not related to graphics have also seen large changes. For example, Qt Concurrent has undergone an almost complete rewrite and now makes development of multi-threaded applications more effortless than ever. Qt Network has seen lots of clean-up and improvements. See this blog post for details.
