The first major update for mini.css v2 (Fermion) adds a plethora of new features:

• A brand new tooltip component
• Predefined layouts for the grid system, media object pattern documentation
• Sticky headers and footers
• Fluid input groups
• Accessibility updates and guidelines for most modules and components

Apart from the above, both flavors have been updated to the latest version, some styling changes have been made to existing components, bugs have been squashed, shortcoming documented and big chunks of the codebase optimized. Finally, some aesthetic changes have been made to the documentation pages.
