To celebrate the holidays and 20 years of Symfony, we’re offering a special gift to the community 🎁 Watch Fabien Potencier’s keynote “20 Years of Symfony, What’s Next?” — free and available now.

This week, most Symfony contributors were enjoying the holidays, so development activity focused on miscellaneous bug fixes. Meanwhile, we released the first tagged version of Symfony AI, as the first step on the road to a stable release.

This week, we published an article about how we controlled 1,200 screens in real time with Symfony during SymfonyCon Amsterdam 2025. We also celebrated a new SymfonyCasts course on building Symfony bundles. Finally, we shared a blog post detailing 20 years of Symfony coding in numbers.

A look at 20 years of Symfony through code statistics, revealing how contributions, complexity, and long-term design choices shaped the framework.

Ever wondered what makes a great Symfony bundle? This new SymfonyCasts course takes you from an empty directory to a production-ready bundle that feels right at home in the Symfony ecosystem.

At SymfonyCon 2025, we wanted to celebrate Symfony’s 20th anniversary with a live, collective experience: 1200 developers holding up their phones while we lit up their screens in real time from the stage. To make that work reliably, we combined Symfony/PHP-FPM for the application logic with a dedicated Mercure/FrankenPHP setup for long‑lived connections, giving us both robustness and massive concurrency. This post walks through the architecture and lessons learned from turning a “simple” colored screen idea into a live demo that worked flawlessly in front of a full conference hall.
