Compatibility issue with Symfony 3.x & 4.x

[ghost]

Dear Madam or Sir,

We have a project which use Cocorico Community Edition with this CocoricoSwiftReaderBundle.

We want to migrate our project to the last LTS version of Symfony (3.x) but your bundle conflict with symfony/symfony and symfony/framework-bundle.

I saw that you intend to migrate Cocorico Community Edition to Symfony 3.4 (the last LTS version) but is it also the case for that bundle as well or not?

(Because, if that's not the case, we'll have to replace it.)

Pending your answer, I would ask you to approve the expression of my sincere most distinguished greetings.

Sincerely.
