Say goodbye to context switching and the "stash-and-switch" headache. By leveraging Git Worktrees alongside modern AI agents, you can now isolate environments and handle bug fixes in parallel while your AI builds features in the background. It’s a total DX game-changer that turns your Git workflow into a multi-threaded powerhouse.
In a previous article, we explored how to generate your first PDF in a few lines of code using Gotenberg and GotenbergBundle, a Symfony bundle that wraps Gotenberg's HTTP API to convert HTML or Office files into PDFs. That was a great start. But what happens when your application needs to generate multiple different PDFs, each with its own layout, styles, data?
The final curtain has fallen on SymfonyLive Paris 2026, and we're still buzzing ✨ (and seeing lines of code). As Symfony's creator and a long-time core sponsor, SensioLabs couldn't have picked a better moment to celebrate open source, innovation, and, most importantly, the amazing community that supports us.

Agile frameworks, such as Scrum and Kanban, are well-known for helping teams focus more effectively on creating value and adapting to changes more easily. However, agility doesn't stop at the team level. Some approaches also address decision-makers and organizations. Evidence-Based Management is one such approach, offering a different perspective with its structured value and progress management based on concrete evidence.

This year was extra special because it was the 20th anniversary of Symfony. SensioLabs was there: we'll tell you all about our experience there!
For business leaders: why testing matters for ROI, risk reduction, and agility explained in management language with numbers and real case studies.
Code review is an essential step in the software development cycle. It improves code quality, reduces bugs, and encourages knowledge sharing within the team. GitLab and GitHub, two of the most popular code management platforms, offer advanced features to facilitate this process. This article covers the various types of code reviews, how to organize them, and how to use templates and checklists to make PRs (pull requests) more efficient.
