What are minor upgrades¶
Minor upgrades contain bugfixes and security updates. They never contain new features and do not break backwards compatibility.
For example, upgrading from TYPO3 version
11.5.3 is a minor upgrade.
The pre-upgrade tasks chapter contains a list of tasks that should be actioned prior to upgrading to a major release.
Check if updates are available¶
There are two ways to check if a minor update is available for an installation of TYPO3.
All supported versions of TYPO3 and their version numbers are published on get.typo3.org.
composer outdated "typo3/*" will present a list of any packages that have updates.
Execute the upgrade¶
To execute the upgrade, run
composer update -W typo3/*.
This will upgrade all TYPO3 packages, the
--with-all-dependencies) signals that any dependencies should also be upgraded.
Once Composer has finished upgrading the installation of TYPO3, log in to the backend and clear all caches.
