New 'Change the look' options

Question

I just installed a new Developer tenant and noticed some nice changes:

These options are not available in my other Enterprise tenant. Does anyone know when they'll be released? A footer would be amazing in our Intranet

Answer 1

They will be available in First release tenants by February 2019.

By end of March 2019, they will be available in all standard release tenants.
