SEDE needs its footer updating from this:
To the new one:
Meta Stack Exchange is a question and answer site for meta-discussion of the Stack Exchange family of Q&A websites. It only takes a minute to sign up.Sign up to join this community
I've submitted a pull request for this the other day, although it's to just remove the list of sites altogether (and synchronize the CSS a little):
Linking to the full list of Stack Exchange sites seemed more practical than attempting to keep the footer up to date with all of those categories.
Additionally, the legal page will now point to the version on the Stack Exchange hub to avoid inconsistencies that arise from changes there, and the contact link points to the contact page on Meta instead of the team email.
