FLTK 1.4.0 brings Wayland support

FLTK 1.4.0 has been released. This new version of the Fast Light Toolkit contains some major improvements, such as Wayland support on both Linux and FreeBSD. X11 and Wayland are both supported by default, and applications using FLTK will launch using Wayland if available, and otherwise fall back to starting with X11. This new release also brings HiDPI support on Linux and Windows, and improves said support on macOS. Those are the headline features, but there's more changes here, of course, as well as the usual round of bugfixes.

Right after the release of 1.4.0, a quick bugfix release, version 1.4.0-1, was released to address an issue in 1.4.0 - a build error on a single test program on Windows, when using Visual Studio. Not exactly a major bug, but great to see the team fix it so rapidly.
