A new PSR-14 event is added that allows to modify the categories to be assigned to an event. The event itself (including already existing categories) as well as the list of categories to be used after import are available. It is possible to change the categories to be assigned, e.g. keep some of the existing categories. That way it is possible for installations to add custom categories to events. Relates: #10623
TYPO3 Events Extension
A basic events extension
This is shared as is. It is developed and used by the agency for some years already. The code and test coverage dates back some years. We continuously try to improve the overall situation. Don't expect heavy documentation at this state.
The main benefit is an import of destination.one events into TYPO3. More info: https://www.destination.one/ You might find old references to "destination data" within the code as there was a rebranding.
