Qt will be introducing a "start-up license" to help small companies make use of the Qt tool-kit for commercial desktop and mobile applications. The Qt open-source licenses have also now been updated.

Going forward, new versions of Qt will be under a commercial license, GPLv2, GPLv3, and LGPLv3. However, the difference is that LGPLv2.1 will no longer be there. Qt is also working to unify their product offering.

More details on these Qt licensing changes via today's press release.
