A number of months ago I wrote about plans for some of the Wayland code to be re-licensed under the LGPLv2. That didn't happen and now Kristian is looking at a new license for the Wayland reference code.

Instead of the LGPLv2, Kristian Høgsberg is now looking at moving the "wayland-demos" code from the GPL to the MIT license. " The intention was to make it easier to move code between the reference implementation and the actual libraries, but another goal is to facilitate easy code sharing between the sample compositor and other Wayland compositors. So instead, I'm going to go for the more pragmatic option of just moving the remaining GPLv2 code in the wayland-demos repo the MIT license instead."

There's few copyright holders on this code, and they are all in favor of this change, so there shouldn't be any issues. There's a mailing list thread about the Wayland licensing code change on the Wayland-devel mailing list.
