The Evolution of Symfony: Now and to the Future!

With the release of 6.2, Symfony will contain somewhere near *500* new features from just the past 12 months! Wow!

And, while many of these are small, the landscape of *how* Symfony apps are developed continues to evolve. In this talk, we'll look at some of the most important changes, from new dependency injection attributes, framework-extra bundle features in Symfony, Symfony UX, testing, and more! Basically... a quick catch-up on 12 months, *thousands* of commits, and hundreds of releases across numerous repositories. Let's go!
