I am trying to create a custom post type for a software project. The details like description and screens are kept with the post. Additionally, I need to attach each version of the software to the single project. Each new version has unique information like version number and release date but things like title and description are obviously the same as all the other versions. I don't want to have to create a new project each time there is an update but I am having a hard time coming up with anything different. Any ideas on how I should approach this?
