Fedimint Files

Self-hosting a gateway just got easy. Gateways use Iroh now, so they work behind NAT with no firewall rules or domain setup. The Gateway UI makes it simple to manage your Gateway's Lightning channels, on-chain wallet, and ecash wallet across federations. Run it as a standalone Docker service or look for packages on Umbrel and Start9 coming soon after release.

Breaking Changes

ConnectorRegistry replaces Connector enum. The networking layer has been refactored. Connector is replaced by ConnectorRegistry from the new fedimint-connectors crate, which supports multiple transport protocols (WebSocket, Iroh, HTTP, Tor). ClientBuilder::open() and ClientBuilder::preview() signatures have changed accordingly.

RocksDb now uses builder pattern. Construction changed from direct instantiation to RocksDb::build().open().

Balance methods renamed for clarity. Methods like get_balance() are now get_balance_for_btc() to support multi-currency.

P2PConnectionStatus struct replaces Option\<Duration>. RTT is now returned as a struct rather than an optional duration.
