Aug 1, 2025August 2025 (2025-08) monthly summary for smithy-rs: Delivered two key capabilities that strengthen reliability and developer experience. First, robust AWS SSO credentials error handling with test gating behind the sso feature flag, reducing user confusion and improving CI signal. Second, configurable and buildable RetryPartition components (TokenBucket and ClientRateLimiter) with updated tests, TOML configurations, codegen tests, and documentation to support flexible retry strategies. These changes improve production reliability, enable more nuanced rate control, and streamline adoption for downstream clients. Additionally, the work refined API surface and documentation to reduce maintenance burden while clarifying sharing semantics of the retry components.
