Frequently asked questions
Is Qt 6.10 still safe to use?
Qt 6.10 left standard support on 7 Apr 2026. It still receives security updates under extended support until 7 Oct 2026 — 59 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download Qt 6.10?
Yes — the final release (6.10.3) generally remains available from vendor archives and OS package mirrors, but installing it means running software with known, unpatched vulnerabilities.
What should I upgrade Qt 6.10 to?
Upgrade to Qt 6.11, the newest actively supported branch (supported until 22 Sept 2026).
