[Fedorator] updating images in fedorator

Hello, Not sure what is going on with my fedorator. I edited releases.py to have version 27. When I run python releases.py it said that there is not tqdm module to import. Weird as it ran well to have isos for fedora 26. I updated raspian but there was not python-tqdm. I installed python pip and then installed tqdm. Now it complains that loading json has no option for encoding. Erased encoding="utf-8" It said that there is nothing to dowload. Cleared the iso directory and started to download ... but it is dowloading version 26 ... which now makes sense that it has nothing to dowload, as it had all files for 26 previous my action of delete. Any hints? I am willingly to try and give feedback. Best regards Neville
