AI made engineers faster. It didn't make teams faster. The constraint was never typing; it was everything around it. The SDLC is being rewritten, and we'd like to rewrite it with you. That's why we're introducing Upsun Dispatch. 🚀 Launching September 2026 👉 Read the story: upsun.com/blog/introdu...

Great teaser for the upcoming #PHP documentary. Super happy to be part of it. #symfony

Nowadays I barely write code without an LLM, and my OSS contribs has gone through the roof. Look at #Twig. Steve Yegge's 8 levels of AI-assisted development described my last 2 years exactly. But at the org level, challenges are different. So I tried to map an org scale: upsun.com/blog/8-stage...

Most engineering teams already use AI. The real gap is whether the whole org is moving together. @fabien.potencier.org maps 8 stages of AI maturity, from leadership silence to autonomous agents. See where your team stands 👉 upsun.com/blog/8-stage...

As an OSS maintainer, my new rule is that anything a frontier model can find with some reasonable effort is a 0-day. Hence why I'm now shipping security releases on public holidays.

#symfony #twig New security releases are scheduled for tomorrow.

During the last few weeks, the #Symfony core team has been hard at work fixing a long list of vulnerabilities for both #Symfony and #Twig. Today, we're publishing that work in the biggest security patch releases ever. Bare with us and wish us luck 🍀

🔥 On démarre la journée à #Symfony_Live Paris 2026 ! Fabien Potencier, @fabpot ouvre le bal avec “Concevoir des TUI en PHP” 💻✨ TUI, Symfony Terminal, et même une PR en live 👀🚀 Let’s go Paris! 🇫🇷🔥 #Symfony #PHP #TechEvent

💻 Pour cette édition #Symfony_Live Paris 2026, Fabien Potencier (@fabpot) enchaîne deux talks ! ⚡ Cette session : "Développer un Coding Agent en PHP : dans les coulisses du "Harness"” ! #PHP #Symfony #TechEvent

My favorite activity when coding: remove code My new favorite activity with my coding agents: let them remove code they generated 😂 Also, I like removing cruft from AGENTS.md or SKILLS.md files Writing code is also about removing code 😀

🤖Fabien Potencier: Keynote à #Symfony_Live Paris 2026 ! “Développer un Coding Agent en PHP : dans les coulisses du 'Harness'” Rendez-vous le 26 mars ! 👀✨ #Symfony #PHP #IA #CodingAgent https://symfony.com/blog/symfonylive-paris-2026-developper-un-coding-agent-en-php-dans-les-coulisses-du-harness

I like when both the agent and me think the same at about the same time. I was about to send it a steer message saying "Stop over-engineer the solutions" when it "thought" the same "Let me undo my overengineered approach and keep it simple. The original ..."

Join #Symfony in London, UK! 💻✨💂 A #MeetUp with great talks, tips from the Core Team, and Symfony community 🙌 🎤 On stage: ➡️Nicolas Grekas: “A Year of Symfony!” 🚀 ➡️Yannick Chenot: “Escaping the Code Maze” 🧩 📍WeWork, 90 York Way, London N1 (Floor 7) 🎟️Tickets: www.meetup.com/symfony/even... #PHP

2026 might be the year every developer wants to build their own agent (coding, personal, ...). A bit like frameworks 10/15 years ago. Great learning exercise and highly recommend as a weekend project.

This morning, I woke up energized and eager to code. Two years ago, I presented a Terminal component at #SymfonyCon, but never published it due to its flawed design. I've now started over with a better plan to address these challenges. Let's see how far I can go. #symfony

Today, at SymfonyCon, we're celebrating 20 years of #Symfony in Amsterdam! Thank you all for your support.

Symfony 7.4 brings a cleaner way to define console inputs: command arguments and options can now be mapped directly to PHP classes and enums using attributes like `#[MapInput]`, `#[Argument]`, and `#[Option]`. Type-safe, structured input for your CLI commands 🎉🍕🥓 #Symfony #PHP #DX

🎉 Something epic is coming for Symfony’s 20th anniversary… 📖 A comic book telling the story of Symfony, 20 years in the making, like never before. Can you guess what it is? #Symfony #DevCommunity #PHP
