Jul 1, 2025July 2025: Delivered security, stability, and serialization improvements in the corda/corda repository, with targeted feature delivery and rigorous test maintenance. Upgraded Jackson to 2.19.1 to leverage newer features and security patches, and removed an unused property collector override in CordaModule.kt for cleaner configuration. A test reliability issue led to a temporary downgrade of constants.properties to 2.17.3 to restore test stability. Implemented a serialization visibility fix to ensure fields on CordaSerializable classes are preserved during property collection, accompanied by minor formatting cleanups. These changes reduce test flakiness, improve runtime stability, and strengthen the security posture, supporting safer deployments and smoother releases.

May 1, 2025Month: 2025-05 summary for corda/corda. Strengthened vulnerability-scanning readiness across multi-module fat-jar builds through publishing and packaging improvements, standardized POM metadata across publications, and tightened test capsule artifact handling. Aligned the publishing flow with the 4.11 baseline by forward-merging scannable jars updates to ensure scanner compatibility and artifact visibility. Improved artifact taxonomy with a more suitable classifier and clearer documentation to aid maintenance and tooling integration. Overall, these efforts reduce packaging variability, improve security posture, and enable faster, safer delivery of updated artifacts.
