Month 2025-01: Delivered a robust overhaul of the filter parsing engine for scenario metadata in znsio/specmatic, providing reliable, TMF-aware filtering capabilities. Key changes include introduction of FilterSymbols, refactoring of FilterSyntax, improved tokenizer robustness, and consolidation of filter grouping logic, accompanied by targeted code cleanup to remove legacy constructs. Expanded test coverage now includes TMF-specific scenarios and combined METHOD/PATH conditions, increasing confidence in production releases and reducing regression risk.

Month 2024-12: Delivered the Advanced Scenario Filtering Engine for znsio/specmatic, unifying filterNot and filter into a single conditional and extending support to AND/OR and not equals. Introduced a modular FilterParser and parsing enhancements to support nested and negated expressions, boosting robustness and test coverage. Architectural refactors improved maintainability and set the foundation for future enhancements in the scenario-filtering feature.

Month: 2024-11 — Documentation-focused sprint delivering comprehensive updates across Specmatic documentation, with emphasis on test hooks, overlays, OpenAPI discriminator support, and configuration guidance. The work enhances developer onboarding, reduces adoption friction, and improves maintainability for long-term product usage.
