 # Changelog
 
+## 2025-12-04 - 4.0.0 - BREAKING CHANGE(typedrouter)
+Introduce options object for TypedRouter.routeAndAddResponse (localRequest, skipHooks); add defaultRouteOptions and make hook calls respect skipHooks; bump package version to 3.2.3
+
+- Changed TypedRouter.routeAndAddResponse signature to accept an options object ({ localRequest?: boolean; skipHooks?: boolean }) instead of a boolean second argument — this is a breaking API change.
+- Added TypedRouter.defaultRouteOptions with defaults { localRequest: false, skipHooks: false }.
+- Routing now respects options.localRequest and options.skipHooks; hook calls (onIncomingRequest, onOutgoingResponse, onIncomingResponse) are skipped when skipHooks is true to avoid hook recursion or duplicate handling (useful for broadcast-received messages).
+- Bumped package.json version to 3.2.3.
+
+## 2025-12-04 - 3.2.2 - fix(typedrequest)
+Add skipHooks flag to TypedRequest to optionally suppress global hooks for internal requests
+
+- Introduce public skipHooks boolean on TypedRequest (default false) with documentation comment explaining it should be used for internal/logging requests to prevent infinite loops.
+- Guard calls to global hooks (onOutgoingRequest and onIncomingResponse) in TypedRequest.fire() so hooks are not invoked when skipHooks is true.
+
+## 2025-12-04 - 3.2.1 - fix(typedrouter)
+Use globalThis-backed globalHooks for TypedRouter to enable cross-bundle sharing; fix merging and clearing of global hooks.
+
+- Replace static globalHooks field with getter/setter that stores hooks on globalThis so hooks are shared across bundles.
+- Fix setGlobalHooks to merge new hooks with existing ones (avoiding accidental overwrite).
+- Update clearGlobalHooks to clear the globalThis storage used for hooks.
+
+## 2025-12-04 - 3.2.0 - feat(typedrouter)
+Add request/response hooks and monitoring to TypedRouter; emit hooks from TypedRequest; improve VirtualStream encoding/decoding; re-export hook types
+
+- Introduce ITypedRequestLogEntry and ITypedRouterHooks interfaces to represent structured traffic log entries and hook callbacks.
+- Add static globalHooks on TypedRouter with helper APIs TypedRouter.setGlobalHooks and TypedRouter.clearGlobalHooks for global traffic monitoring.
+- Add instance-level hooks on TypedRouter (setHooks) and a unified callHook() that invokes both global and instance hooks safely (errors are caught and logged).
+- TypedRequest now emits onOutgoingRequest before sending and onIncomingResponse after receiving, including timestamps, duration and payload/error details.
+- TypedRouter now emits lifecycle hooks while routing: onIncomingRequest when a request arrives, onOutgoingResponse for responses (both success and handler-missing error cases), and onIncomingResponse when responses arrive to be fulfilled.
+- VirtualStream.encodePayloadForNetwork and decodePayloadFromNetwork were enhanced to recurse into arrays and nested objects (preserving special built-ins) to correctly handle embedded virtual streams.
+- Re-export ITypedRequestLogEntry and ITypedRouterHooks from the package index for external consumption.
+
 ## 2025-12-03 - 3.1.11 - fix(virtualstream)
 Expose transport localData to handlers via TypedTools; improve VirtualStream payload encode/decode to preserve built-ins and handle nested arrays/objects
