Under the edit field (e.g https://commons.wikimedia.org/w/index.php?title=User:Josve05a&action=edit) it says " Creative Commons Attribution-ShareAlike 3.0 license and the GFDL. " but the link at the legal footer at the bottom of all pages link to 4.0. I know that content licensed under 4.0 can't be relicensed to 3.0, but content under 3.0 can be relicensed to 4.0. If we change the legal footer bar to 3.0, will that have legal effects to content submitted while the legal footer had a link to 4.0? Or are we relicening everything to 4.0?
