.@extend is crucial to future #CSS development (like Firebug crucial): #Maintenance cc/ @TheSassWay

It is now possible to define a custom importer that can be used to find imports using different import semantics than the default filesystem importer that Sass provides. For instance, you can use this to generate imports on the fly, look them up from a database, or implement different file naming conventions. See the Importer Base class for more information. It is now possible to define a custom cache store to allow for efficient caching of Sass files using alternative cache stores like memcached in environments where a writable filesystem is not available or where the cache need to be shared across many servers for dynamically generated stylesheet environments. See the CacheStore Base class for more information.
