Symfony 4 support

[Tristan Bessoussa]

This bundle does not support Symfony4. Unless this bundle isn't maintained, which should be mentionned, Symfony4 should be added.

Hi @tristanbes, thanks for getting involved. I've added a link to the (in-progress) PR that addresses this.

[Martin Hujer]

@sampart this can be closed as the Symfony 4 support was merged in the linked PR.

Good spot. Thanks, @mhujer.
