 - **BREAKING:** Gateway auth mode "none" is removed; gateway now requires token/password (Tailscale Serve identity still allowed).
 
 ### Fixes
+- Gateway: suppress AbortError and transient network errors in unhandled rejections. (#2451) Thanks @Glucksberg.
+- TTS: keep /tts status replies on text-only commands and avoid duplicate block-stream audio. (#2451) Thanks @Glucksberg.
 - Security: pin npm overrides to keep tar@7.5.4 for install toolchains.
 - Security: properly test Windows ACL audit for config includes. (#2403) Thanks @dominicnunez.
 - CLI: recognize versioned Node executables when parsing argv. (#2490) Thanks @David-Marsh-Photo.
