Three months after its previous 25.08 release, Niri, a Wayland compositor known for its scrollable-tiling layout, where windows are arranged in columns on an infinite strip, rolls out a new 25.11 version, bringing many improvements.

The headline feature is the new Alt-Tab switcher, developed through multiple design iterations. It shows large live previews, fades long window titles, and properly masks windows blocked from screencasts.

Because Niri users often work with many terminal windows, the switcher operates on windows rather than applications, and it uses a debounce delay so that transient focus changes don’t pollute the recent-windows list. It can also scope switching to the current workspace or monitor.
