When do you plan to have v4 ready, so we can start changing code and make new builds? When will documentation be updated? When will sample code be updated?
Here is a quote from your documentation:
Because Facebook deprecates versions of their Graph API approximately every two years, the original facebook plugin will no longer function once Graph API v2.1 is deprecated. Thus, on October 30, 2016, migrating to the facebook-v4 plugin will be required.
So when will this get priority? With 1,7 billion users, it’s a great login system.
