 ### Version 0.7 (4 April 2014)
 
 This version introduces optional integrations into Symfony2, Silex and Twig. You can still use the library in any other framework. I decided to include these bridges because there exist integrations from other developers, but they use outdated versions of cocur/slugify. Including these small bridge classes in the library makes maintaining them a lot easier for me.
