 # Changelog
 ## [Unreleased]
 
+### Changed
+- Core: Refactored connection monitoring from polling to event-driven D-Bus signals for faster response times and lower CPU usage ([#46](https://github.com/cachebag/nmrs/issues/46))
+- Core: Replaced `tokio` with `futures-timer` for runtime-agnostic async support (fixes GTK/glib compatibility)
+
+### Added
+- Core: `ActiveConnectionState` and `ConnectionStateReason` enums for detailed connection status tracking ([#46](https://github.com/cachebag/nmrs/issues/46))
+- Core: `monitor_network_changes()` API for real-time network list updates via D-Bus signals
+- Core: `NetworkManager` is now `Clone`
+
+### Fixed
+- Core: `forget()` now verifies device is disconnected before deleting saved connections ([#124](https://github.com/cachebag/nmrs/issues/124))
+- Core: `list_networks()` preserves security flags when deduplicating APs ([#123](https://github.com/cachebag/nmrs/issues/123))
+- Core: Fixed race condition in signal subscription where rapid state changes could be missed
+- GUI: Fixed UI freeze when connecting/forgetting networks
+
 ## [0.4.0-beta] - 2025-12-11
 ### **Breaking Changes**
 - **nmrs**: Expanded `ConnectionError` enum with new variants (`AuthFailed`, `SupplicantConfigFailed`, `SupplicantTimeout`, `DhcpFailed`, `Timeout`, `Stuck`, `NoWifiDevice`, `WifiNotReady`, `NoSavedConnection`, `Failed(StateReason)`) - exhaustive matches will need a wildcard ([#82](https://github.com/cachebag/nmrs/issues/82))
