I'm starting a new project with Symfony and I was wondering if I should use Symfony 4 or 3.4 considering the fact that Symfony 4 has a lot of changes and new mindset.
So, if I use Symfony 4 will all the popular bundles (FOS...etc) be compatible with Symfony 4? Also has anyone faced any compatibility issue when using Symfony 4 compared to 3.4?
You can still find most of those libraries (bundles) on the Symfony's recipes server, you can look for your current libraries to check if they were moved to Symfony 4 or not:
And check the Github repo if you want to learn more about Recipes :
