# CONFLICTS This document explains why certain conflicts were added to `composer.json` and references related issues. - `doctrine/orm:>= 2.16.0` This version makes Sylius Fixtures loading fail on the product review fixtures. References: https://github.com/doctrine/orm/issues/10869 - `stof/doctrine-extensions-bundle:1.8.0` This version introduced configuring the metadata cache for the extensions, what breaks the `Timestampable` behaviour. This package is not exactly the root of the problem, but it started using a bugged feature of the `gedmo/doctrine-extensions` package. References: - https://github.com/stof/StofDoctrineExtensionsBundle/issues/455 - https://github.com/doctrine-extensions/DoctrineExtensions/issues/2600 - `twig/twig:3.9.0`: This version has a bug, which lead to a fatal error: `An exception has been thrown during the rendering of a template ("Warning: Undefined variable $blocks").`
