Important: #98484 - Extensions outside of document root for Composer-based TYPO3 installations¶
TYPO3 v12 requires the Composer plugin
typo3/cms-composer-installers with v5,
which automatically installs extensions into Composer's
directory, just like any other regular dependency.
However, in order to allow linking and rendering assets in the public web folder, the TYPO3 installation symlinks public folders to a specific location. For more details and the background about the change, read more:
Please note that this only affects TYPO3 installations in Composer mode.
