About Signal Desktop
Signal Desktop ships steady notification controls while holding firm on its minimalist philosophy.
Signal Desktop is in its standard beta rhythm — incremental weekly releases that ship small UX refinements and bug fixes, with occasional substantive features. The v8.27.0 beta cycle delivered genuine notification controls: per-muted-thread preferences, app badge customization, and a restore-defaults button. Outside that, the last month is largely maintenance: text zoom options, group search UX tweaks, and performance passes. Nothing here signals a product pivoting or expanding its scope.
