Now that I compare the sub-folder of the latest zip to the root of a prior one, I am seeing more differences. So in addition to the new parent folder, this describes changes to some documentation, additional license files, and some texture folders. Ultimately, this could be a tool for someone to use who wants to summarize the differences after all parties are done making changes and the zip is being created and uploaded to the download folder. This is the result of comparing just one of the zips to a prior version.
