TYPO3 Version and Release Management

Release Information

For every (E)LTS version, you can look up:

• which releases there have been (e.g. 13.4.0, 13.4.1, 13.4.2, etc.)
• what kind of release it is (maintenance/security)
• what the release contains ("release notes")

You can find more information on individual major releases here (including download options):

• Release information for version 14
• Release information for version 13
• Release information for version 12
• Release information for version 11
• Release information for version 10

Where Do I Find the Version Numbers?

Alongside the TYPO3 version, the PHP version is also important for your system's security. Your TYPO3 instance should run on at least PHP 8.2 (supported until 2026-12-31), 8.3 (supported until 2027-12-31) or 8.4 (supported until 2028-12-31) – TYPO3 versions 12, 13 and 14 support these PHP versions.

You can find the software versions in use (TYPO3, PHP, database) in the TYPO3 backend via the list icon in the top right. There you'll also see the installation method (Composer or classic mode), the web server, the operating system in use, the scheduler's last run, and any errors that occurred, with a link to the system log. The "application context" indicates whether you're in a test or production environment.

In TYPO3, you should generally only use long-term versions – these are always the latest minor versions of a major release, i.e. 14.3, 13.4, 12.4, 11.5, and so on. The minor versions below that (e.g. 13.0–13.3) are called sprint releases and aren't suitable for production use. The two most recent major releases each receive Long Term Support (LTS).

Long Term Support (LTS)

LTS versions receive free maintenance and security updates for 1.5 years, and a further 1.5 years of security updates only, also free of charge.

Extended Long Term Support (ELTS)

Extended Long Term Support (ELTS) is a paid support offering from TYPO3 GmbH for TYPO3 versions that drop out of LTS after three years. Typically, ELTS is offered for two major versions at a time – so if v14 and v13 are in LTS, ELTS is offered for v12 and v11. Security updates continue to be delivered as part of this service.

You can learn how to find out about released patches and how to apply them in our article on TYPO3 security updates.

TYPO3 Roadmap

The TYPO3 Association regularly updates its development work via a roadmap. It shows which TYPO3 versions remain in LTS or ELTS status, and for how long: typo3.org/cms/roadmap

PHP

What Is PHP?

PHP is a server-side scripting language used to generate dynamic web pages. It runs on the web server and loads and processes content from databases, then sends it to the browser as finished HTML.

What Role Does PHP Play for TYPO3?

PHP is essential for TYPO3, since the entire CMS is built on it. TYPO3 is fully written in PHP – from the core to the backend to the extensions.

Notes

Make sure that PHP, the programming language TYPO3 runs on, is also updated regularly. Any version below 8.2 should no longer be used. You can find the official PHP roadmap at php.net/supported-versions.php.
