version control - old links

Hi

I'm interested to know how people manage version control for Rise courses.  I had an incident where someone reviewed an old link and thought I hadn't done any updates that they asked for, but I had copied the old course and made changes to the copy.  Is there anyway to stop people from using old links?  I'm aware that you can apply a password when you share it but can you then change that password to ensure if they try to use the link again,  they cannot view it or is it a case that once you have added a password you can not change it?

thanks in advance
