You knew API Platform back in version 2.6 and still think you know how to use it? Bad news: what you did yesterday is probably obsolete today.

Since version 3, and especially version 4 released last September, API Platform has completely transformed: new philosophy, new mechanisms, new developer experience. In short, the framework has grown — and your old habits might now work against you.

In this talk, we will:
- take stock of what version 4 really means,
- dissect the major changes (and what they imply in practice),
- list common mistakes made when coding “like before,”
- and give you the right reflexes to get the most out of the new version.

Whether you’re coming from v2.6 or just starting out, this talk will help you stop fighting the framework… and finally enjoy its full power.
