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.

Dec 1, 2024December 2024: Cordite/corda project focused on hardening core libraries and simplifying dependency management to enhance security, stability, and maintainability. Completed a targeted upgrade of core dependencies (Jackson and Netty) across the core library stack and removed outdated version constraints. This reduces risk for downstream deployments, enables smoother future upgrades, and improves long-term maintainability. The work also included cleanup of unnecessary overrides to minimize potential conflicts and streamline maintenance workflows.

Nov 1, 2024Month: 2024-11. This period focused on stabilizing the corda/corda build while keeping docs current and future-upgrade readiness. Key feature delivered: Documentation Update for Bouncy Castle Javadoc links — updated the BC package list URL in build.gradle to reference the latest package information, ensuring accurate docs generation and reducing future maintenance with docs tooling. Major bug fix: Jackson version compatibility — reverted Jackson from 2.17.2 to 2.13.5 to resolve compatibility issues with Kotlin dependencies, preventing build failures and enabling continued Kotlin-based development. Impact and accomplishments: Kept the build green and docs accurate, reducing downstream risk and improving developer onboarding; established a stable baseline for upcoming upgrades. Technologies/skills demonstrated: Gradle build configuration, dependency management, version pinning and rollback, Bouncy Castle/Javadoc maintenance, Jackson dependency management, Kotlin compatibility considerations.
