What's New in Qt 6

Qt 6 is the latest version of Qt. It lets you develop applications with intuitive user interfaces for multiple targets, faster than ever before.

Qt 6 is highly compatible with Qt 5. Developers of Qt 5 applications can move seamlessly to Qt 6 while retaining the current functionality, and gradually develop new features that leverage what Qt 6 makes possible.

Qt Essential, Qt Add-ons, and Qt Marketplace

In Qt 6, a new structure streamlines the base installation. The base installation includes primarily the Qt Essentials and a few of the most commonly used Qt Add-Ons. The Qt Add-Ons are moved outside of the main installation, but still available when needed. With the new Qt Marketplace, other add-ons can be installed. In Qt 6, the installation experience is easier and flexible.

Cross-Platform Portability

Cross-platform portability is made simpler in Qt 6, thanks to the modularized codebase and with Qt Platform Abstraction.
