Patch/Bugfix update

What are patch/bugfix updates

Patch/Bugfix updates contain bugfixes and security updates. They never contain new features and do not break backwards compatibility.

For example, updating from TYPO3 version 11.5.2 to 11.5.3 is a patch/bugfix update.

Before updating

The pre-upgrade tasks chapter contains a list of tasks that should be actioned prior to upgrading to a major release.

The only tasks that need to actioned for a patch/bugfix update are making a backup and updating the reference index.

Check if updates are available

There are two ways to check if a patch/bugfix update is available for an installation of TYPO3.

All supported versions of TYPO3 and their version numbers are published on

Alternatively, running composer outdated -m "typo3/*" will present a list of any TYPO3 packages that have patch/bugfix updates.

Execute the update

To execute the update, run composer update --with-all-dependencies "typo3/*".

This will update all TYPO3 packages, the --with-all-dependencies signals that any dependencies of TYPO3 should also be updated.

Post update

Once Composer has finished updating the installation of TYPO3, log in to the backend and clear all caches.
