Keeping high code quality: how hard can it be?

Session en anglais - Débutant

Keeping good code quality is always a challenge (even harder if you share your work with the world). It becomes crucial for every project maintainer to define and execute technical quality standards, to make not only their, but all the project's users' lives easier. Based on my experience in maintaining Sylius, I will present a variety of techniques to ensure good DX in your project (from testing to low-level technical requirements)

What's (technically) new with Sylius in 2025?
