Great new things are coming with the latest Qt release. Read more about asset conditioning support in Qt, rewritten compiler pipeline for QML and JavaScript engine, unification of 3D engines, Qt Location updates, printing support for Linux, to name a few. This version of Qt will be officially supported for one year, but keep in mind that, if needed, you may always extend the support lifetime of your Qt release!

Our CTO Lars Knoll shares an overview of this and more in the release blog.

Maurice Kalinowski shows a complete building automation demo based on Qt and KNX.


Qt for Automation's QtKNX is the smart home library that translates your wishes into the KNX protocol.

Qt KNX is the first major step to bring home automation at the finger tips of Qt users. Multi-platform, elegant, flexible and easy to write software for smart homes will soon be possible. All it takes is the new QtKNX library, and the already existing functionalities of Qt.

Michael Winkelmann shows you how Qt for WebAssembly lets you build Qt applications for web browsers. Code once, deploy everywhere - even on the web! 

Qt for WebAssembly Tech Preview

WebAssembly is now supported by all major web browsers as a binary format for allowing sand-boxed executable code in web pages that is nearly as fast as native machine code. Qt for WebAssembly makes it possible to run Qt applications on many web browsers, without any download steps or special server requirements (other than serving the wasm file). Check out the examples directly in your browser!

basysKom's Frank Meerkötter shows off an industrial HMI built with Qt Quick and Qt OPC/UA.

Qt OPC UA Tech Preview

OPC UA is a central element of the Industry 4.0 story providing seamless communication between IT and industrial production systems. The focus of Qt OPC UA is on HMI/application development and ease of use for client-side development. The Tech Preview allows to connect to servers, read and write attributes, call methods on the server, monitor values for data changes and browse nodes. All this functionality is provided by asynchronous APIs which integrate nicely into Qt applications.
