 - Browser/screenshots: stop sending `fromSurface: false` on CDP screenshots so managed Chrome 146+ browsers can capture images again. (#60682) Thanks @mvanhorn.
 - Mattermost/slash commands: harden native slash-command callback token validation to use constant-time secret comparison, matching the existing interaction-token path.
 - Control UI/mobile chat: reduce narrow-screen overflow by shrinking the chat pane minimum width, removing extra mobile padding, widening message groups, and hiding avatars on very small screens. (#60220) Thanks @macdao.
+- Android/Talk Mode: route spoken replies through `talk.speak`, keep compressed playback cleanup deterministic, and fall back to local TTS for legacy gateways that omit Talk error reasons. (#60954) Thanks @obviyus.
+- Android/Talk Mode: keep reply-speaker routing and teardown behavior aligned with the new remote playback path. (#60954) Thanks @MKV21.
