Hi @darinda !

Thank you for this PR! Is this everything that needs to be done to support eZ 3 and Symfony 5?

In any case, I will need to spend some time on the package before it is released to support eZ 3, but finding the time might prove challenging.

Hey @emodric ,

unfortunately no. There are some cross-dependencies to https://github.com/netgen/NetgenInformationCollectionBundle which are yet to be solved. Unfortunately infocollection bundle itself is still in an alpha phase concering it's eZ 3 support.

I'll most probably create a separate branch for making enhanced binary file bundle compatible with information collection bundle, though. I'll issue another PR for this, when it's done.
