The Qt Company · Dev / Framework · 1 supported · 18 end-of-life · updated June 2026 · what is end-of-life? →
This is when each Qt release line stops receiving security updates. 1 release line is still supported — the next to reach end-of-life is Qt 6.11 on 22 Sept 2026. Running an end-of-life version means new vulnerabilities stay unpatched.

Qt end-of-life — frequently asked
What Qt versions are still supported?
As of June 2026, these Qt release lines still receive security updates: 6.11. The latest supported release is 6.11.1. Versions older than these (6.10, 6.9, 6.8, 6.7, 6.6, 6.5, 6.4, 6.3, 6.2, 5.12, 6.1, 6.0, 5.14, 5.15, 5.13, 5.9, 5.6, 4.8) are end-of-life and no longer patched.
When does Qt 6.11 reach end of life?
Qt 6.11 reaches end-of-life on 22 Sept 2026 — about 3 months away. After that date it stops receiving security patches.
Is Qt end-of-life?
No — Qt still has supported release lines (6.11). But individual older versions are end-of-life, so what matters is the specific version you run.
How do I know when my Qt version reaches end of life?
Check the version you run on its product page, or monitor Qt on IsItPatched to get an email alert before the release line you use reaches end-of-life — so you can upgrade in time.
