December 2024 monthly summary: This cycle focused on delivering business value through improved data interoperability, bookmarking capabilities, and release readiness for Scout 25.1. Key outcomes span both repositories: scout.docs and scout.rt. - DataObjects support in Scout JS: Migrated interfaces to classes and enhanced data serialization to improve interoperability with Scout Java backends, enabling type-safe data exchange and reducing client-side boilerplate. - Scout 25.1 documentation/build updates: Updated build requirements, plugin migrations, and version references across the migration guide, docs, and site content to align with Scout 25.1 (Maven/git-commit-id-plugin changes, plugin groupId updates, homepage/domain changes, and version bumps). - Bookmarking enhancements in Scout RT: Introduced PageResolver for bookmarking and refactor creation/activation; UUID-based identification to support bookmarking and inspector functionalities. - Test robustness improvements: Made tests order-independent for interface hierarchy to ensure deterministic test results. - Build, documentation, and dependency hygiene: Standardized dependency management with Selenium BOM, updated build config, and refreshed project documentation and references. Overall impact: Accelerated, reliable integration between Scout JS clients and the Java backend; improved test reliability and CI feedback; and a cleaner upgrade path for Scout 25.x with better maintainability and developer productivity.
