The ctcsound repo has been transferred from https://github.com/fggp to https://github.com/csound. All links to the previous repository location are automatically redirected to the new location. However, to avoid confusion, I recommend updating any existing local clones to point to the new repository URL. You can do this with the following command from your local clone:

git remote set-url origin https://github.com/csound/ctcsound
