The fix for DDC-2624 had a side effect on recomputation of changesets in preUpdate events. The method wasn't adjusted to the changes in its sister method computeChangeSet() and had wrong assumptions about the computation. Especially: 1. Collections have to be skipped 2. Comparison was changed to strict equality only.

Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
