+# Changelog
+
+## 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
+
+- TypedHandler: pass typedRequest.localData into a TypedTools instance so handlers can access transport-layer context (e.g. websocket peer).
+- TypedTools: add a public localData property to store transport-specific context available to handlers.
+- VirtualStream.decodePayloadFromNetwork: preserve built-in objects (Set, Map, Date, RegExp, Error, Promise or thenable) to avoid incorrect transformation.
+- VirtualStream.encodePayloadForNetwork / decodePayloadFromNetwork: added proper recursion for arrays and objects to correctly handle nested payloads and virtual streams, with path tracking to support deduplication logic.
+
+## 2024-10-16 - 3.1.10 - fix(VirtualStream)
+Fix stream closure logic in `writeToWebstream` method
+
+- Added `writer.releaseLock()` call before closing WritableStream when `closingBit` is received in `writeToWebstream` method.
+
+## 2024-10-16 - 3.1.9 - fix(VirtualStream)
+Ensure writable streams are correctly closed asynchronously to prevent potential sync issues.
+
+- Updated VirtualStream to use 'await' when closing writable streams, ensuring proper asynchronous handling.
+
+## 2024-10-16 - 3.1.8 - fix(VirtualStream)
+Fix stream closing behavior to correctly handle closing bits
+
+- Introduced a 'closingBit' constant to properly signal the end of stream data.
+- Updated the 'readFromWebstream' function to send a closing bit upon completion if 'closeAfterReading' is true.
+- Modified the 'close' method to optionally send a closing bit when terminating the stream.
+
+## 2024-10-16 - 3.1.7 - fix(VirtualStream)
+Fix issue in VirtualStream to handle null values during data writing.
+
+- Ensured writableStream closes gracefully when null values are encountered.
+- Added a null check before writing data to the writableStream to prevent errors.
+
+## 2024-10-16 - 3.1.6 - fix(VirtualStream)
+Fix backpressure handling in VirtualStream workOnQueue method
+
+- Resolved an issue in the workOnQueue method of VirtualStream where concurrent execution was not properly managed.
+- Introduced a workingDeferred promise to ensure proper queue handling and resolve potential race conditions.
+
+## 2024-10-16 - 3.1.5 - fix(virtualstream)
+Add console log for debugging backpressure feedback loop
+
+- Inserted a console log message to provide insight when waiting due to backpressure in the workOnQueue method.
+
+## 2024-10-16 - 3.1.4 - fix(VirtualStream)
+Corrected the logic for backpressure handling in response
+
+- Fixed backpressure flag assignment in the response handling logic of VirtualStream.
+- Ensured correct negation logic for checking receive backpressure status.
+
+## 2024-10-14 - 3.1.3 - fix(VirtualStream)
+Fix keepAlive flag handling in VirtualStream and added stream closure in tests
+
+- Ensure that the keepAlive status is correctly maintained in the keepAlive trigger method.
+- Added closure of VirtualStreams in the test suite for proper resource cleanup.
+
+## 2024-10-14 - 3.1.2 - fix(core)
+Fix incorrect backpressure logic in VirtualStream class
+
+- Corrected the logic for determining backpressure status by checking the available space in the receiveBackpressuredArray.
+- Introduced a looping mechanism to wait when the other side is backpressured before sending more data.
+
+## 2024-10-14 - 3.1.1 - fix(virtualstream)
+Fix handling of virtual streams for proper shutdown
+
+- Ensured that writeToWebstream method checks for remaining items in receiveBackpressuredArray before closing.
+- Corrected package.json dependency for @push.rocks/tapbundle.
+- Updated @types/node to version 22.7.5.
+
+## 2024-10-11 - 3.1.0 - feat(virtualstream)
+Enhance VirtualStream with optional closure when reading from webstream
+
+- Added an optional parameter `closeAfterReading` to the `readFromWebstream` method.
+- The stream will close automatically after reading if `closeAfterReading` is set to true.
+
+## 2024-10-11 - 3.0.33 - fix(test)
+Increase delay duration before stopping the server in test suite.
+
+- Adjusted the delay time from 1000 ms to 10000 ms before stopping the server to ensure tests complete smoothly.
+
+## 2024-09-06 - 3.0.32 - fix(virtualstream)
+Fix keep-alive loop handling and test cleanup
+
+- Prevent unnecessary keep-alive loop from starting on the responding side
+- Add logging for keep-alive loop initiation in VirtualStream
+- Temporarily comment out stream close and tap forceful stop in test to avoid abrupt termination
+
+## 2024-09-06 - 3.0.31 - fix(core)
+Updated dependencies and added close method to VirtualStream
+
+- Updated dependencies in package.json for better compatibility
+- Added close method to VirtualStream class in ts/classes.virtualstream.ts for more graceful stream termination
+
+## 2024-05-31 - 3.0.28 - Error Handling
+Enhancement to error handling mechanisms.
+
+- Logs now include the method to which an error was given.
+
+## 2023-08-04 - 3.0.0 - Core
+Introduced a breaking change.
+
+- Major update to core functionalities.
