Wayland Gets a License Fix

A problem with Wayland’s license was recently uncovered when a Wikipedia editor pointed out a discrepancy between the license statement in the project’s FAQ, and the license found in the actual code. The code was licensed under a Historical Permission Notice and Disclaimer (HPND) license when it should have been licensed under MIT. This confusion arose out of the project’s initial plan to retain full compatibility with the X11 window manager license, but the license text was copied from an older version of X11. Our own Bryce Harrington submitted the patch to apply the correct license to the code and address this problem, and it appears there will be little to no problem implementing the new license.

This engine is not yet available for the average user to download and use, but the community hopes to make its updates a part of GIMP starting with version 2.10.
