+## [0.6.7] — 2026-08-22
+
+### Changed
+- **All system audio is now the safe screen-share choice.** On supported
+  PixelPass builds, the single **All system audio** row shares ordinary desktop
+  sound while excluding PeerSpeak's own call playback. There is no longer a
+  second, technical-sounding desktop-audio choice to understand before sharing.
+
+### Fixed
+- **Sharing desktop audio no longer sends the call back to its listeners.**
+  PeerSpeak marks every playback path it owns, passes the active echo-canceller
+  identity to PixelPass, and uses a fail-closed PipeWire fan-out so voice,
+  watched shares, and notification sounds cannot enter the screen-share mix.
+- **Screen-share audio failures are visible without becoming unsafe.** Missing,
+  unsupported, or newly unsafe streams stay out of the capture and produce a
+  useful warning; warnings clear again when the condition or share ends.
+- **Stopped and failed shares clean up promptly.** Remote viewers and their
+  players are reaped when a stream ends, and leaving a call tears down the
+  PixelPass host, capture graph, and viewer processes instead of leaving a
+  stale sharing state or warning behind.
+
+### Packaging
+- **The Linux AppImage bundles the matching PixelPass helper.** The one-file
+  build therefore carries the desktop-audio exclusion capability it advertises
+  rather than depending on an unrelated system PixelPass version.
+
+### Compatibility
+- **Wire-compatible with 0.6.6.** This release changes local screen-share audio
+  routing and lifecycle behavior; no PeerSpeak audio, friends, files, or gossip
+  protocol version changed.
