Events to modify link handler
You may have to modify the list of available link handlers based on
some dynamic value.
Changed in version 12.0: Starting with TYPO3 version 12.0 you can use the following PSR-14 events:
Supporting both TYPO3 v12 and v11 to modify the available link handlers
If you want to be compatible to both TYPO3 v12 and v11, you can keep your
implementation of the hooks
described in Hooks and implement the
event listeners at the same time. Remove the hook implementation upon dropping
TYPO3 v11 support.
