This release introduces a new feature: a "delete" reaction. This is useful when the import reaction is used to handle an item at a time and not a full dataset. In such a case, the deletion cannot be handled automatically, since External Import does not have the entire dataset for comparison. This way, it is possible to handle such a scenario from within External Import, without having to develop a custom reaction. Read the documentation for more details: https://docs.typo3.org/p/cobweb/external_import/main/en-us/User/Reaction/Index.html
The release also includes a minor bugfix improving the handling of null substructures.
