This is the first release of the new EasyAdmin 4.x version 🎉 This is the first EasyAdmin release to support Symfony 6.x (in addition to Symfony 5.x).
This version has the exact same features as 3.5.16, but both branches (3.x and 4.x) will start diverging soon and only 4.x will get new features. Update your Symfony 5.x and 6.x to EasyAdmin 4.x as soon as possible.
