PackagesMayHaveChangedEvent
New in version 10.3
The event was introduced to replace the Signal/Slot
\TYPO3\.
The PSR-14 event \TYPO3\
is a marker event to ensure that Core is re-triggering the package ordering and
package listings.
Attention
This event is dispatched when an extension is changed in the Extension Manager, therefore starting with TYPO3 v11 this event is only dispatched in legacy installations, not in Composer-based installations. Use installer events by Composer for Composer-based installations.
