May 2025 monthly summary for breez SDK Greenlight: Implemented BreezServices lifecycle management and graceful shutdown within the Breez SDK Greenlight CLI. Centralized BreezServices under a CommandHandler, introduced an abort command for testing, and improved shutdown robustness by ensuring ongoing tasks complete before disconnection using the sender's closed status. These changes reduce shutdown risk, improve reliability in production, and enhance testability.

In March 2025, delivered performance and build optimizations for Breez SDK (breez/breez-sdk-greenlight). Focused on runtime efficiency and developer productivity to enable faster iteration and more robust SDK behavior. Key changes include a performance refactor of BreezServer and ApiKeyInterceptor to remove redundant clones and switch to into_iter for chain_api_servers, plus adding a development build profile to Cargo.toml for sdk-cli to speed up development builds by enabling debuginfo and reducing unnecessary debug symbols. These changes improve runtime efficiency, reduce build times, and lay groundwork for faster delivery of SDK improvements to clients.
