Mar 1, 2026March 2026: Stabilized the caching and backoff behavior in aws/aws-sdk-java-v2 by fixing the exponential backoff calculation in maxStaleFailureJitter. This prevents negative jitter values and avoids unintended caching behavior, improving retry reliability and cache correctness for clients. Overall impact: Enhanced reliability and predictability of client retries under transient errors, reducing risk of cache-related instability across Java SDK users. This contributes to higher service resilience and smoother developer experience in production systems using the AWS SDK for Java v2. Technologies/skills demonstrated: Java, retry/backoff algorithms, caching strategies, code hygiene and auditability through a dedicated commit (3ea1b37a2d022ae2e376943ec2cc9573042dced2).

Sep 1, 2025September 2025 (2025-09): Focused stabilization of JSON processing in aws/aws-sdk-java-v2 by rolling back the Jackson library upgrade to 2.19.0 to restore stable behavior. The INCLUDE_SOURCE_IN_LOCATION setting of JsonFactory had been disabled during the upgrade; the rollback reverts that behavior and remedies incompatibilities, ensuring consistent client parsing and preventing regressions in downstream JSON handling.
