The CakePHP dev's have made it super simple to display your cakephp version, I have only just stumbled across it when looking for something else in the API. Like me you might not have spotted it, its not an essential bit of code but a nice to have for those administering many sites on various servers and much better than finding the version text file on each install. I display the version number in the system setup part of the sites admin dashboard along with other framework related settings...
