I'd like to get back to my proposed update of the KDE licence policy https://community.kde.org/Policies/Licensing_Policy/Draft
I got some comments from Matija Šuklje which I incorporated and it now includes a handy changelog. -Note that Qt is LGPL 3 not 2.1 -Code copied from Qt can be GPL 3 as well as GPL 2, check comparible with your code -Allow AGPL for web apps -Encourage AGPL for web apps -Allow icons to be CC-BY-SA 4 -Allow media files to be CC-BY-SA 4 and no longer allow CC-BY-SA 3 -Note CC-BY-SA 4 is LGPL 3 compatible -Documentation to be CC-BY-SA 4 -MIT text now one of the more standard variants (modern style with sublicence) -Links to SPDX licences The main change is for docs and other non-code files to become CC-BY-SA 4. This allows it to be converted to code (it's one-way compatible with LGPL 3) and allows us to share with other popular sources such as wikipedia. CC-BY-SA 4 is also better maintained, better understood and internationally recognised than the old FDL licence. Jonathan
