⁠Versioning

GRUBRUBY_IMAGE_VERSION starts versioning 8001 to not be confused with Ruby patchlevels. To understand the versioning of these images, we use the following format:

RUBY_MAJOR.RUBY_MINOR.RUBY_MINOR.GRUBRUBY_IMAGE_VERSION

So if you download version 2.5.1.8001 you are getting Ruby-version 2.5.1 and version 8001 of Grubruby.
