[Guitone](http:\/\/guitone.thomaskeller.biz), my little GUI frontend for the [monotone SCM](http:\/\/www.monotone.ca), is currently licensed according to the terms of the GPLv3+ and was previously – before version 0.8 – licensed under GPLv2+. Newer development however forces me to re-license it again, this time under slightly less restrictive “copyleft” terms, under LGPLv3.<\/p>\n
The reason for this is my usage of the [Graphviz library](http:\/\/www.graphviz.org) to render monotone revision trees. Graphviz is released under EPL (older versions under CPL even), and this license is strictly incompatible to any pure GPL version. I contacted the Graphviz guys and I also contacted the legal affairs support of the FSF and checked the options I had and the result is now that I have to adapt, one way or another. I could either use the “command line interface” of Graphviz or choose another license for guitone. I didn’t want to go the first route, simply because I have a working implementation and because I didn’t want to make slow calls into external binaries, so a new license had to be chosen on my side.<\/p>\n
So, starting with the upcoming version 1.0 guitone is licensed under LGPLv3. I contacted the previous contributors of guitone and all parties are ok with the license change, so the actual license change will pop up in the [current development’s head shortly](https:\/\/code.monotone.ca\/p\/guitone\/source\/tree\/h:net.venge.monotone.guitone\/).<\/p>\n
