Jan 1, 2026January 2026 monthly summary for the helidon monorepo. Focused on stabilizing builds by cleaning up dependency management in the http-media-json module and applying a targeted fix for dependency analysis. These changes reduce build failures, prevent transitive dependency issues from affecting releases, and improve CI reliability for faster feedback and delivery. Key improvements include stabilizing the http-media-json module’s dependencies and Maven configuration, and implementing a dependency:analyze-only fix to prevent false positives during analysis (commit 5aac016d8946976f5b5e4384302a52a45364fa78, referenced by #11077).
