[edit] Notes
- Note 0: Was never revised.
- Note 1: Compatible to version 3 of the GPL but not compatible to version 2.
- Note 2: 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]
- Note 3: Incompatible with the BSD license.
- Note 4: Only the modified license, without the advertising clause.
