Sylius 2 migration won’t get simpler because you postpone it. You’ll just have less time, more pressure, and fewer calm decisions.
That’s why we built practical Sylius 2 planning resources: checklist + Plugin Compatibility Radar.

The Summit is canceled. But we’re still meeting in Poznań on May 24 🇵🇱
We can’t imagine a year without community energy.
That’s why we’re launching PHPers Day. Smaller but still full of heart.

The first centuries after Christ were a time of intense development of religion. Evangelists played a not insignificant role in this process. Let's watch @mpzalewski talk: The Shines and Shadows of #BDD.
