UPGRADE FROM 2.4 to 2.5

PHP requirements

  • MongoDB ODM 2.5 requires PHP 7.4 or newer. If you're not running PHP 7.4 yet, it's recommended that you upgrade to PHP 7.4 before upgrading ODM.

doctrine/collections v2 compatibility

ODM supports doctrine/collections 2.x along 1.x. Please note that we added findFirst(...) and reduce(...) methods to comply with the new Collection interface. Make sure signatures of new methods comply with your own ones, should you have implemented such methods before.
