 ### Fixes
 
 - Telegram: pass `parentPeer` for forum topic binding inheritance so group-level bindings apply to all topics within the group. (#9789, fixes #9545, #9351)
+- CLI: pass `--disable-warning=ExperimentalWarning` as a Node CLI option when respawning (avoid disallowed `NODE_OPTIONS` usage; fixes npm pack). (#9691) Thanks @18-RAJAT.
 - CLI: resolve bundled Chrome extension assets by walking up to the nearest assets directory; add resolver and clipboard tests. (#8914) Thanks @kelvinCB.
 - Tests: stabilize Windows ACL coverage with deterministic os.userInfo mocking. (#9335) Thanks @M00N7682.
 - Heartbeat: allow explicit accountId routing for multi-account channels. (#8702) Thanks @lsh411.
