• Jenkins — Replaced sleep-based waits in QueueTest with Awaitility-based condition polling, improving test readability and reducing timing assumptions.
  PR merged: jenkinsci/jenkins#26786

• Spring Boot — Polished code to use Java instanceof pattern matching in condition handling, improving readability and removing redundant casts.
  PR merged: spring-projects/spring-boot#50419

• Apache Seata — Removed an external network dependency from HttpClientUtilTest, making the test suite more reliable and deterministic.
  PR merged: apache/incubator-seata#8099

• Floci — Refactored digest encoding to use JDK HexFormat, replacing manual byte-to-hex conversion with a cleaner standard-library approach.
  PR merged: floci-io/floci#772

• Byte Buddy — Improved diagnostics for external agent attachment by enhancing the generated debugging output for troubleshooting attachment failures.
  PR merged: raphw/byte-buddy#1901

• Apache Empire-db — Fixed an off-by-one issue in StringUtils.lastIndexOfAny and added test coverage for the corrected behavior.
  PR merged: apache/empire-db#20

• Caffeine — Simplified cache name snapshot creation while preserving behavior and improving implementation clarity.
  PR merged: ben-manes/caffeine#1955

• Spring Framework — Polished collection usage in HttpHeadersTests, improving test readability and modernizing collection construction.
  PR merged: spring-projects/spring-framework#36760
