+## [0.4.5] - 2022-10-15
+
+### Added
+
+- Support for peering over UNIX sockets is now available, by configuring `Listen` and peering URIs in the `unix:///path/to/socket.sock` format
+
+### Changed
+
+- `yggdrasilctl` has been refactored and now has cleaner output
+- It is now possible to `addPeer` and `removePeer` using the admin socket again
+- The `getSessions` admin socket call reports number of bytes received and transmitted again
+- The link setup code has been refactored, making it easier to support new peering types in the future
+- Yggdrasil now maintains configuration internally, rather than relying on a shared and potentially mutable structure
+
+### Fixed
+
+- Tracking information about expired root nodes has been fixed, which should hopefully resolve issues with reparenting and connection failures when the root node disappears
+- A bug in the mobile framework code which caused a crash on Android when multicast failed to set up has been fixed
+- Yggdrasil should now shut down gracefully and clean up correctly when running as a Windows service
+
