Qt End of Life Dates

Developers rely on cross-platform application development frameworks to create graphical user interfaces and applications that can run seamlessly on various software and hardware platforms, including Linux, Windows, macOS, Android, and embedded systems. Qt, a framework created to address this need, has been maintained by The Qt Company since its inception. With a history of providing a comprehensive set of libraries and tools, Qt has become a go-to solution for developers looking to build applications that can run across different platforms. The framework's versatility and extensive community support have made it a popular choice among developers.

The Qt framework has undergone significant evolution over the years, with a total of 19 versions released. Currently, 18 of these versions have reached their end-of-life, leaving only one active version. The latest stable version, 6.11.1, is the current standard for developers. However, version 6.11 is slated to reach its end-of-life on September 22, 2026, marking an important milestone for developers who need to plan their application maintenance and updates accordingly. The most recent end-of-life date was April 7, 2026, for version 6.10, demonstrating the ongoing evolution of the framework.

The security landscape for Qt is remarkably clean, with a total of 0 CVEs tracked and no critical vulnerabilities reported. As a result, there is no most affected version, and the framework is not listed on the Known Exploited Vulnerabilities catalog. This pristine security record is a testament to the framework's robust design and the diligence of its maintainers. Developers using Qt can focus on building their applications without the burden of addressing known security vulnerabilities, allowing them to concentrate on creating innovative and reliable software solutions. To ensure continued support and security, developers should keep their Qt versions up to date and plan for future updates and migrations.
