FLTK 1.4 will be in Ubuntu 25.10 "Questing Quokka" 25.10 when released

[Manolo]

I've upgraded my Ubuntu 25.04 to 25.10 beta and noticed FLTK 1.4.3

is available there as a standard package. Therefore FKTK 1.4 will soon

be available for Ubuntu users: Ubuntu 25.10 "Questing Quokka" release is 

announced for Oct 9, 2025.

Noticeably, Ubuntu 25.10 removes support for X11-only user sessions

and offers only Wayland-based sessions. Although Wayland sessions

do run X11 programs, it's good FLTK transitioned to Wayland in parallel

with version 1.4.
