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
11.5.3 is a patch/bugfix update.
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 get.typo3.org.
composer outdated -m "typo3/*" will present a list of any TYPO3 packages that have patch/bugfix updates.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.
Once Composer has finished updating the installation of TYPO3, log in to the backend and clear all caches.
