[samuelvi]

Hi, are you going to support Symfony 4? thanks!

[jsamouh]

any update ?

Not sure it will be needed as Symfony 4.1 will handle route translation natively : https://symfony.com/blog/new-in-symfony-4-1-internationalized-routing

@remmel yeah but that means people/organizations currently using this Bundle will need to rewrite all their routing configuration (and that can be quite a large task depending on your application..).
