May 1, 2025May 2025 (fedimint/fedimint): Key features delivered include Esplora-based data access and environment simplification (removed electrs; added optional esplora port for mutinynet/regtest) and API usability improvements (public FeeConsensus fields; LNv2 select_gateway exposed). Major bugs fixed include crypto provider initialization robustness (lazy initialization with tokio::sync::OnceCell; ensure provider is installed before API client connects), on-chain payments reserves handling fix (retain_reserves set to false), WASM build fix for the Lightning invoice crate (Bolt11InvoiceDescriptionRef reference), gateway federations re-registration after LN connect, and Esplora URL handling correctness improvements (unit tests; improved URL parsing). Maintenance and tooling updates include dependency bumps, Nix lock updates, clippy lint fixes, and test/script adjustments for ldk-node logs. Overall impact: reduced runtime errors, more reliable LN connectivity and API client integrations, and a smoother developer experience with enhanced maintainability. Technologies/skills demonstrated: Rust async patterns (tokio, OnceCell), WASM compatibility adjustments, unit testing, Nix/Flakes tooling, dependency management, and proactive maintenance practices.
