Just improved Caddy performance by fixing header casing on the hot path! 🚀 When using Go's net/http, make sure to use canonical HTTP header casing (e.g. Content-Type instead of content-type). Non-canonical keys trigger string formatting and allocations on every lookup. https://github.com/caddyserver/caddy/pull/7911#pullrequestreview-4817897747

🛡️ Symfony Docker now provides a rootless production image that contains only what is strictly necessary to run #FrankenPHP and #Symfony.

They are 60% smaller than before, dropping from 704MB down to just 290MB! 📉✨

We have also merged numerous improvements, such as:

✍️ Use of EOF syntax in the Dockerfile for better readability
🧹 Automatic removal of code only needed during installation

Windows Support for FrankenPHP: It’s Finally Alive! - Kévin Dunglas

It’s happening! I am thrilled to announce the immediate availability of official Windows support for FrankenPHP. Since the project's initial release, this has been by far the most requested feature. While many of you have been successfully running FrankenPHP on Windows via WSL (Windows Subsystem for Linux), native support was the "white whale" we’ve been

I've just dramatically improved my "Symfony Docker" project.

It now supports Dev Containers, autonomous (YOLO) coding agents such as Claude Code, Xdebug out of the box, instantaneous hot reloading with FrankenPHP, and slim, rootless images for production. 🐘

I presented these features at SymfonyLive Paris. Here is the detailed breakdown and the slides from my talk: https://dunglas.dev/2026/03/coding-at-the-speed-of-thought-the-new-era-of-symfony-docker/

Coding at the Speed of Thought: The New Era of Symfony Docker - Kévin Dunglas

If we want to discuss Developer Experience (DX) in 2026, we have to talk about instantaneous feedback and coding agents. At SymfonyLive Paris 2026, I presented "Coding at the Speed of Thought: Symfony DX in 2026", where I detailed the bleeding-edge features we have brought to the PHP and Symfony ecosystems. To make this vision

J'ai même été personnellement menacé par un membre du PS qui m'a lancé "viens, on sort" devant toutes les personnes présentes car je tentais de faire respecter les procédures démocratiques. Des problèmes similaires se sont répétés dans un très grand nombre de bureaux de vote. Malgré ces méthodes d'un autre âge, ils n'ont pas pu stopper la vague. Ne décevons pas l'espoir qui se lève. Unissons-nous !

@lukasrotermund@social.tchncs.de Not sure I'm following you. Symfony Docker has always focused on dev envs setup, and Docker is ideal for safely running coding agents. Use what you like, though!
