Qt LTS: Long-Term Support Releases

Ensure development stability and reliability with Qt Framework’s Long-Term Support (LTS) releases. When your development team needs a solid foundation that ensures your applications run smoothly and can withstand challenges over time, Qt LTS is the answer.

Stability Above All

The Qt LTS releases prioritize maintaining existing features, ensuring your applications run smoothly across different platforms and devices for years without backward compatibility issues and regressions.

Support and Maintenance

Qt LTS comes with dedicated technical support, security patches and bug fixes, ensuring your software remains robust, secure and stable over the long haul, while Qt minimizes the hassle of unexpected disruptions for you.

Strategic Predictability

In released environments for e.g. business applications and embedded systems, Qt LTS protects your investment, allowing for predictability and consistency. Your team can devote more energy to innovation rather than upkeep.

Maintenance for
at Least 5 Years

The Qt LTS releases are Minor releases and a part of the regular Qt Framework release cycle.

Qt LTS Release Cycle

New Qt LTS release every 2 years;
Every 4th Minor release is an LTS release.
Each LTS release is maintained for 5 years. (From Qt 6.8 onwards)
The maintenance period can be further expanded. Additional commercial or professional services available.

Discover the Release Cycle

The Qt Long-Term Support (LTS) is the cornerstone of a robust development strategy.

Stability and Reliability over the Years

The Qt LTS releases are dedicated Qt Framework Minor releases, designed to provide long-term stability. Typically used for products in production, the Qt LTS releases enable maintaining system consistency with predictable development cycles and maintenance costs.

Qt LTS releases are available with the Commercial Qt licenses.

Easier Regulatory Compliance

With the tightening cybersecurity regulations, such as the EU Cyber Resilience Act (CRA), obligations on e.g. vulnerability management and lifecycle security updates are significantly easier to comply with the longer maintenance periods and ready-made building blocks offered by Qt LTS. They provide the Maintenance releases and security patches throughout the years, and allow preparing for the update to the next LTS in an organized manner.

What About After the LTS Maintenance Period?

If you need support, maintenance, or security patching beyond the standard Qt LTS maintenance period, there are possibilities to extend the support and security maintenance period, depending on which release you are using.
