## Version 2.1.1 (2025-01-08)

### Bug Fixes

* **Fixed response mutation during redaction**: The v2.1.0 performance optimization inadvertently caused API response data to be mutated when event handlers were registered. This resulted in sensitive fields (like tokens) being replaced with `[REDACTED]` in the actual response returned to the caller, causing authentication failures. The `dataResponse` is now deep-cloned before redaction to preserve the original data.

## Version 2.1.0 (2024-12-09)

### New Features

* **Session Invalidation**: Added `invalidateSession()` method for proper logout handling. This method:
  * Stops the action queue to prevent new requests
  * Waits for pending requests to complete (configurable timeout)
  * Deletes session cookies (`frontastic-session` and `__rememberMe`)
  * Prevents "zombie session" issues where stale cookies persist after logout

* **Queue Improvements**: Added `flush()` method to wait for all queued actions to complete before proceeding. Useful for session invalidation and cleanup scenarios.

* **Event Handler Check**: Added `hasEventHandlers()` method to EventManager for checking if handlers are registered for specific events.

### Performance Improvements

* **Eliminated deep cloning**: Replaced expensive `JSON.parse(JSON.stringify())` operations with targeted shallow copies
* **Skip event processing when no handlers**: Event handling methods now return early if no handlers are registered, providing zero overhead when events aren't used
* **Single redaction pass**: Redaction now happens once per API call instead of once per event
