+Noctalia v5.0.0-beta.6 or newer — the first tagged release that accepts
+`plugin_api = 15`, which the panel's settings shortcut
+(`noctalia.openSettings()`) needs — and `topgrade` on `PATH`. A terminal emulator is needed for the update run:
 the plugin uses Noctalia's own detection (`$TERMINAL`, then `ghostty`, `kitty`,
 `alacritty`, `wezterm`, `foot`, `konsole`, `gnome-terminal`, `ptyxis`, `xterm`),
 or the one named in the **Terminal** setting.
