Breaking: #84744 - Raise doctrine/dbal-version

See forge#84744


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 -.


Users not having prefixes in DateInterval fields will be greeted by a ConversionException.

We do not expect many (if any) TYPO3 users to be affected by this change.

You can read up on the topic at and

Affected Installations

Users with existing DateInterval fields that don't yet use the proper field prefix.


Manually provide the proper prefixes in your DateInterval fields.

If you didn't use negative DateIntervals yet, you can safely prefix your data with +.
