- TYPO3 v12: Free support ended on 30 April 2026. Anyone who still requires security updates will need to upgrade or purchase an ELTS licence.
- TYPO3 v13: Security updates until the end of December 2027.
- TYPO3 v14: released in April 2026, bug fixes until the end of December 2027, security updates until the end of June 2029. Currently the most sensible option for upgrades.
- TYPO3 v11 and earlier: now only supported via ELTS, with a limited remaining support period.
What is ELTS? Extended Long-Term Support is a paid maintenance service provided by TYPO3 GmbH for versions whose regular support has expired. You will continue to receive security patches, but no new features. ELTS is therefore an extension, not a solution: licence fees are payable annually and will also expire at some point.
We’ll advise you on which option is more cost-effective in your case. For an installation with many custom extensions and a tight budget, ELTS for one year may be the right decision. In most cases, upgrading is the more economical option, as you’ll then be back on the regular support cycle.
