Full Release Notes

## ⚠️ Breaking Changes

- `iroh`
    - added
        - “passive” mode for mDNS discovery
            - `MdnsDiscovery::new(node_id: NodeId)` → `MdnsDiscovery::new(node_id: NodeId, advertise: bool)`
    - changed
        - The `subscribe` method for the `Discovery` trait now returns a stream of `DiscoveryEvent` rather than a `DiscoveryItem`. A discovery event now includes expiry events that notify you when a node that was passively discovered (usually by mDNS) can no longer be found.
            - `fn subscribe(&self) -> Option<BoxStream<DiscoveryItem>>` → `fn subscribe(&self) -> Option<BoxStream<DiscoveryEvent>>`
