This week, Symfony development activity was very intense and focused mostly on bug fixes. In addition, we added support for the upcoming Twig 4.0 version and fixed some issues related to changes in the upcoming PHP 8.6 version. Lastly, we published the first talks for the SymfonyCon Warsaw 2026 conference.
