 - TUI/Windows: coalesce rapid single-line submit bursts in Git Bash into one multiline message as a fallback when bracketed paste is unavailable, preventing pasted multiline text from being split into multiple sends. (#4986) Thanks @adamkane.
 - TUI: suppress false `(no output)` placeholders for non-local empty final events during concurrent runs, preventing external-channel replies from showing empty assistant bubbles while a local run is still streaming. (#5782) Thanks @LagWizard and @vignesh07.
 - Auto-reply/WhatsApp/TUI/Web: when a final assistant message is `NO_REPLY` and a messaging tool send succeeded, mirror the delivered messaging-tool text into session-visible assistant output so TUI/Web no longer show `NO_REPLY` placeholders. (#7010) Thanks @Morrowind-Xie.
+- Gateway/Chat: harden `chat.send` inbound message handling by rejecting null bytes, stripping unsafe control characters, and normalizing Unicode to NFC before dispatch. (#8593) Thanks @fr33d3m0n.
 - Agents: return an explicit timeout error reply when an embedded run times out before producing any payloads, preventing silent dropped turns during slow cache-refresh transitions. (#16659) Thanks @liaosvcaf and @vignesh07.
 - Agents/OpenAI: force `store=true` for direct OpenAI Responses/Codex runs to preserve multi-turn server-side conversation state, while leaving proxy/non-OpenAI endpoints unchanged. (#16803) Thanks @mark9232 and @vignesh07.
 - CLI/Build: make legacy daemon CLI compatibility shim generation tolerant of minimal tsdown daemon export sets, while preserving restart/register compatibility aliases and surfacing explicit errors for unavailable legacy daemon commands. Thanks @vignesh07.
