Important: #102875 - Updated Dependency: Doctrine DBAL 4

See forge#102875


TYPO3 v13 ships with Doctrine DBAL with at least version 4.0.

TYPO3 extends some Doctrine DBAL classes, enriching behaviour and provide these as public API surface, for example Connection, QueryBuilder and the ExpressionBuilder and are most likely used by extensions. Minor signature changes and removed methods are not mitigated and passed as breaking changes.

Custom extensions using low-level Doctrine DBAL API and functionality directly need to adapt, consult the upgrade guides for Doctrine DBAL on how to migrate.

See Doctrine DBAL 4.0 Upgrade Guide and Doctrine DBAL 3.8 Upgrade Guide for further information about Doctrine DBAL API changes and how to mitigate them.
