Version 3 of the popular Doctrine DBAL library https://www.doctrine-project.org/2020/11/17/dbal-3.0.0.html, almost 10 years after the initial release of version 2. In September 2021, Doctrine ORM 2.10 https://github.com/doctrine/orm/pull/8964, while still supporting DBAL 2 at the same time. Versions prior to 2.10 aren’t compatible with DBAL 3.
Doctrine DBAL has native support for JSON columns. DBAL provides a native type allowing storing PHP arrays as JSON arrays in JSON columns (if supported by the DBMS, otherwise a text column is used) and retrieving them later as PHP arrays.
