Yup, they were released in PBE first!



There are instructions within the app itself. Basically, download it, run it, choose your locale, click change, and let it patch. DO NOT click the "Launch" button on the patcher, instead, click the "Ok" button (or whatever it says, I forget x.x It should be obvious which button, though) on the app and you should be good to go!



You need to run it every time League has a new patch, but other than that everything should work perfectly.
