Notes
- Template:Fnb Was never revised.
- Template:Fnb Compatible to version 3 of the GPL but not compatible to version 2.
- Template:Fnb The original version of the Artistic License is defined as non-free because it is overly vague, not because the substance of the licence. The FSF encourages projects to use the Clarified Artistic License instead.[1]
- Template:Fnb Incompatible with the BSD license.
- Template:Fnb Only the modified license, without the advertising clause.
