Month: 2025-07. This period delivered a stable release baseline and a broad set of quality and reliability improvements across the fandango repository. Key features delivered include the Release 1.0.3 baseline (initial release), configuration updates (pyproject.toml), and groundwork for upcoming releases. The team also expanded validation by incorporating evaluation into tests and performed preparatory work for future releases. Major bugs fixed span code quality, typing, documentation, and core stability, including Black formatting across the codebase, MyPy typing fixes, README and docs updates, SQL query hardening with a new where clause, XML handling fixes, core/REST/script/tar stabilization, dependency maintenance (docutils and missing deps), and extended timeouts for external service calls. The combined changes enhance reliability and repeatable deployments, reduce runtime failures, and improve maintainability. Technologies/skills demonstrated include Python typing and static analysis (MyPy, typing improvements), code formatting with Black, dependency management, test-driven validation (evaluation now part of tests), and robust handling of SQL/XML and external service interactions.
