+Breaking: #84744 - Raise doctrine/dbal-version
+==============================================
+
+See :issue:`84744`
+
+Description
+===========
+
+The upgrade doctrine/dbal to 2.7.1 came with a potentially breaking change that makes
+it necessary to adjust the format of DateInterval fields.
+
+Those fields can now be negative as well and thus are expected to begin with either
+`+` or `-`.
+
+
+Impact
+======
+
+Users not having prefixes in DateInterval fields will be greeted by a :php:`ConversionException`.
+
+We do not expect many (if any) TYPO3 users to be affected by this change.
+
+You can read up on the topic at https://github.com/doctrine/dbal/pull/2579 and https://github.com/doctrine/dbal/releases/tag/v2.7.0.
+
+
+Affected Installations
+======================
+
+Users with existing DateInterval fields that don't yet use the proper field prefix.
+
+
+Migration
+=========
+
+Manually provide the proper prefixes in your DateInterval fields.
+
+If you didn't use negative DateIntervals yet, you can safely prefix your data with `+`.
