Jul 1, 2025July 2025: Performance-focused feature delivery and stability hardening for OpenFrontIO. Key features introduced include: (1) Experimental units flag and UI visibility to hide experimental features in private lobbies and solo games by default; (2) Automatic train stations and early-game automation, connecting factories to the rail network and streamlining infrastructure; (3) Per-player gold pop-up visuals when trade ships land, making earnings and unit gains immediately visible; (4) Emoji table UI improvements with a close button and Tailwind styling for consistent rendering; (5) UnitGrid performance optimization through type-based grouping to reduce CPU usage during lookups. Major fixes address rendering and data integrity: (6) Railroads redrawn in dark mode to prevent disappearances; (7) Memory leak fix in UnitGrid when units move; (8) Conquest FX integration with sword animation and gold transfer display; (9) Accurate attack cancellation logging; (10) Alliance rule enforcing that dead players cannot send alliance requests. Overall, these changes improve early-game pacing, UX clarity, rendering stability, and analytics accuracy.
