+Breaking: #97752 - MailerAdapterInterface removed
+=================================================
+
+See :issue:`97752`
+
+Description
+===========
+
+The :php:`\TYPO3\CMS\Core\Mail\MailerAdapterInterface` has been removed,
+since the interface became unused in v7 due to removal of Core's
+:php:`SwiftMailerAdapter` implementation, which had been used as hook
+subscriber in the also removed :php:`MailUtility::mail()` method.
+
+Impact
+======
+
+Implementing the interface in custom extension code will trigger
+a PHP Error.
+
+Affected installations
+======================
+
+All installations implementing the interface in custom extension code,
+which is very unlikely. The extension scanner will report any usage as
+strong match.
+
+Migration
+=========
+
+Remove any usage of the interface in extension code.
