Mar 1, 2026March 2026 monthly results for smeup/jariko: Focused on reliability, security, and maintainability. Delivered locale-aware BigDecimal parsing with Italian comma support and strict error handling, with tests validating dot and comma formats and cross-platform line ending normalization in RpgParserFacade. Strengthened privacy by removing tracking of local configuration files to prevent accidental sharing of sensitive settings. Improved code quality with a camelCase naming convention refactor for readability and consistency. These changes reduce data parsing errors for international users, harden data privacy, and set a maintainable baseline for future quality improvements.

May 1, 2025May 2025 performance and stability focus for smeup/jariko. Key outcomes include speedups in compile-time data resolution via map-based lookups and tryToResolve, structural data-access improvements with new by-name maps, a clarified feature flag (createSymbolTable not implemented) to reduce risk, targeted refactors of DS builders and input handling for future Kotlin compatibility, and a stability-focused BOMInputStream overhaul with a controlled revert to ensure reliable I/O behavior. These changes improve build speed, API clarity, and overall maintainability, delivering tangible business value in faster iterations and more predictable behavior.
