Is OJS GDPR compliant?

Hi Alec, hi everyone,

I follow up on this in order to ask some further and updated information, hoping also to serve for others to arrive here in the future.
Is this still the final guide to read? https://docs.pkp.sfu.ca/gdpr_pkp_guide.pdf
And then, a very direct question: as per OJS 3.1.4 installation, without any edit to it, is the software already compliant with GDPR or I should consider anyway to add a “privacy&cookie” consent bar, trying to use a free external service for it, for example?
Thank you very much
Leonardo
