Frequently asked questions
Is Qt 6.8 still safe to use?
Qt 6.8 left standard support on 2 Apr 2025. It still receives security updates under extended support until 8 Oct 2029 — 1,156 days from now — but only if you are enrolled. Without it, no fixes reach you.
Can I still download Qt 6.8?
Yes — the final release (6.8.3) 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 6.8 to?
Upgrade to Qt 6.11, the newest actively supported branch (supported until 22 Sept 2026).
