This list helps users to understand whether a particular license > is a free software license, and whether it is compatible with the GNU General > Public License (GNU GPL). Like the previous version of the EUPL (EUPL-1.1), > the EUPL-1.2 is included in the section for free licenses that are GNU > GPL-incompatible, but with an important caveat. While the EUPL-1.2's copyleft > by itself is incompatible with the GNU GPL, the license provides a few > mechanisms for re-licensing which enable combination with GNU GPL-licensed > works. We explain the situation more fully in the entry itself: > > This is a free software license. By itself, it has a copyleft comparable > to the GPL's, and incompatible with it. However, it gives recipients > ways to relicense the work under the terms of other selected licenses, > and some of those -- the Eclipse Public License in particular -- only provide > a weaker copyleft. Thus, developers can't rely on this license to > provide a strong copyleft. > > The EUPL allows relicensing to GPLv2 only and GPLv3 only, because those > licenses are listed as two of the alternative licenses that users may > convert to. It also, indirectly, allows relicensing to GPL version 3 or > any later version, because there is a way to relicense to the CeCILL v2, > and the CeCILL v2 gives a way to relicense to any version of the GNU GPL. > > To do this two-step relicensing, you need to first write a piece of code > which you can license under the CeCILL v2, or find a suitable module > already available that way, and add it to the program. Adding that code > to the EUPL-covered program provides grounds to relicense it to the > CeCILL v2. Then you need to write a piece of code which you can license > under the GPLv3+, or find a suitable module already available that way, > and add it to the program. Adding that code to the CeCILL-covered > program provides grounds to relicense it to GPLv3+. > These comments are very similar to the ones we made for the EUPL-1.1, as the > EUPL-1.2 is an update that is very much in line with its predecessor. The > biggest change was adding the GNU GPLv3 only as an alternative license, > simplifying the process of incorporating EUPL-1.2 code into a GNU GPLv3 only > project. Note, however, that the two-step re-licensing process previously > described is still needed in order to incorporate EUPL-1.2 code into a GNU > GPLv3+ project. > > With all that said, the EUPL-1.2 is the newest addition to our list of free > licenses, but more will be added in the future.
