I’ve started the process of upgrading the theme to use Foundation 4, and I hope to have a beta out sometime this week. I’ve updated the grid and top menu. There is still work to do with Featured Posts using Orbit, the Main Menu (nav-bar which was dropped in F4 and achievable through other ways), and general refinement.
I also want to add Clearing support to gallery posts.
Updates to come later this week.
Update: Base Station 1.0 alpha is now available and comes with Foundation 4.
