Nov 1, 2025November 2025 monthly summary for openfrontio/OpenFrontIO: Stabilized WebSocket logging pathway by fixing a null socket crash, significantly improving connection reliability and log integrity. The fix was implemented with defensive checks in the WebSocket handling logic and validated through targeted tests and code reviews. In addition, I expanded the release package with regression tests, updated internationalization support via translateText() and en.json, and prepared UI update screenshots to accompany release notes. These changes reduce crash risk in production, improve observability of the WebSocket subsystem, and support a smoother developer and user experience.

Jul 1, 2025July 2025 (OpenFrontIO) — Delivered two features and one bug fix that materially improve structure visualization, icon readability, and unit health accuracy. Implemented structure level display on icons/sprites with multi-zoom text overlays using a bitmap font and container-based rendering. Improved UI readability with new icon shapes, a structure-type filter, and refined zoom thresholds/offsets for icons, including support for construction site icons and a texture creation refactor. Fixed health bar display for inactive ships so health bars render only for active units within valid health ranges, with automated tests added. Business impact: faster scene interpretation for operators, reduced visual noise, and more reliable health indicators, contributing to a smoother user experience and lower support overhead. Technical impact: enhanced rendering pipeline, better UI scalability, and maintainability through targeted refactors and tests. Technologies demonstrated: bitmap font rendering, container-based rendering, UI filtering logic, texture creation refactoring, and test-driven validation.
