while discussing download.jboss.org with firstname.lastname@example.org we found
These look to be links to mars and neon.
This is mixing in devstudio versioning with jbosstools which is just really confusing.
No idea what they are for and I haven't seen/noticed any mails or jiras about introducing a new versioning scheme.
I suggest we delete these ASAP since download.jboss.org is already utterly overloaded with different schemes.
