LXQt 2.3 has been released today as the latest stable version of the lightweight desktop environment for Linux-based operating systems, an update that brings new features and improvements.
Coming more than six months after LXQt 2.2, the LXQt 2.3 release introduces a new, more advanced Wayfire backend for the Wayland session, support for adjusting the screen backlight with the mouse wheel on the panel, and support for the ext-workspace-v1 protocol to the Desktop Switcher applet on the panel so that it works with more Wayland compositors.
Fortunately, Debian bookworm will get updates for several years to come.
Iirc, the problem with i386 is that many fundamental libraries and applications no longer officially support the architecture so the Debian team would have to do a lot more debugging.
