Last night Facebook changed the format they use for codes. (codes are an intermediate step in the process of requesting access tokens.) 

This change broke the caching for the convert code step for Django Facebook, breaking login, connect and registration functionality. Fortunately this was quickly reported by developers in a country where there was no Queensday yesterday. 

I encourage everybody to update to 5.0.13 to make sure your Facebook integration keeps on working.
