The 0.4 release of libLicense features a reorganization of the code creating three separate packages. This release introduces KDE4 integration, initial internationalization support and a more polished GTK license chooser. In addition to source files, we've released Fedora i386 and source rpms. Soon we will also release debs, for both Debian and Ubuntu, and updated Gentoo ebuilds.
The new version of the license chooser widgets includes an explicit "No license" option and a new warning about unknown combinations of license attributes.
