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. to 11. is a patch/bugfix update.
Before updating
The pre-upgrade tasks chapter contains a list of tasks that should be completed prior to upgrading to a major release.
The only tasks that need to be completed 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.
Alternatively, running composer outdated - will present a list of any TYPO3 packages that have patch/bugfix updates.
Execute the update
To execute the update, run composer update --.
This will update all TYPO3 packages. The -- signals that any dependencies of TYPO3 should also be updated.
Post update
Once Composer has completed updating the installation of TYPO3, log in to the backend and clear all caches.
