Silex ends as a project in June 2018. Lots of people still using it. Even if Sf4 + Flex ideas are pretty similar to Silex, it takes some time to learn the new concepts and philosophy.

Could we prepare a short upgrading guide for Silex users? It wouldn't be a comprehensive and ultra detailed guide, just a quick overview of the main changes: where to put the app config, how to define services, controllers + routes with annotations, etc.

If you are a Silex developer, please add a comment here telling us what would be the most important things to explain. Thanks!
