Fundamental shift of the usage of Kentucky. Instead of being an additional library to add to your existing or base level code, Kentucky now serves as the base level for all CSS development.
It provides the user with a series of folders, some of which include various files that help jumpstart development by providing mixins, variables, etc.
Kentucky is not meant to be an updatable product as developers should start with it as a core and edit it's included files, in addition to creating their own.
Kentucky's growth will continue but the changes made to it should always be considered incompatible with previous versions.
