This document discusses the release of Symfony 3.0.0 and what is new compared to Symfony 2.x. Symfony 3.0 does not contain any new features, but rather focuses on compatibility layers and removing deprecated code and methods from Symfony 2.8. It provides a simple migration path for updating from Symfony 2.x to 3.0 using Composer. The key changes are removing deprecated functionality, standardizing the directory structure, and increasing the required PHP version to 5.5.9+.
