Thanks Again Trolltech!
As announced just minutes ago at the KDE 4.0 Release Event, Trolltech’s Qt to be licensed under the GPL v3 - both Qt3 and Qt4. Thanks Trolltech, this saves the distributors and everyone quite some license compatibility mess headaches. :-)
"I am very pleased that Trolltech has decided to make Qt available under GPL v3," commented Richard Stallman, author of the GPL and president of The Free Software Foundation. "This will allow parts of KDE to adopt GPL v3, too. Even better, Trolltech has made provisions for a smooth migration to future GPL versions if it approves of them."
