Upgrading extensions
List extensions
Like TYPO3's core, extensions are also composer packages. The composer info command will list all
extensions that are currently installed including their name and current version number.
Check for updates
To check if any extension upgrades are available, composer outdated can be used to display a list
of packages that have updates along with their new version number.
Upgrade an extension (minor)
Minor upgrades of an extension can be done with the composer command composer update vendor/.
Upgrade an extension (major)
Major upgrades of an extension can be done with the composer command composer require vendor/.
