Symfony blog posts for August 2025

This week, Symfony completed the migration to PHPUnit 12 in the 7.4 branch, which required many changes during the past weeks, such as replacing annotations with attributes. In addition, we updated the container XML dumping process to not require the PHP XML extension. Finally, we also published more details about the hackday to be celebrated during the SymfonyCon Amsterdam 2025 conference.

This week, Symfony released the maintenance versions 6.4.24, 7.2.9, and 7.3.2. Meanwhile, we began deprecating the XML configuration format in some components, enhanced the YAML configuration format to support auto-completion and updated the container XML dumping process to remove some dependencies.
