Ghostscript has long been developed under a two-license scheme: new work
would appear in a non-free release, then be placed under the GPL one year
later. No longer: Ghostscript hacker Raph Levien has announced
that the current development version of Ghostscript is now GPL-licensed.
Note that distributors tend to ship a third branch of
based on the (older) GPL version, so it may be a little
while before the leading-edge makes it into distributions. (Thanks to Kurt
