Apr 1, 2026Month 2026-04 focused on hardening cross-platform error handling in SuperTux/supertux. Delivered Windows-specific stack-trace support via preprocessor adjustments and refactored error messaging to use std::string for clarity and safety; standardized SDL Messagebox handling. This work reduces user-facing errors, accelerates debugging, and improves maintainability. Commits fc1087ec44ac60100dab45c9a07fd3c2be2f5a27 and 5ceef208deef809f391e9310577a20dc9bdb75c6 underpin the changes.

Mar 1, 2026March 2026: Key deliveries focused on save-system stability, input/navigation robustness, and release readiness. Implemented Save Versioning and Save State Stability to manage cross-version upgrades, back up old worldmaps, reset save state for new saves, and prevent clobbering during upgrades. Enhanced Input Handling and UI Navigation to avoid menu conflicts with an open console, added SDL 2.26.0-compatible console scrolling, and ensured controller bindings re-establish when switching input types for multiplayer. Advanced release readiness for 0.7.0 with Android/Flatpak builds, CI release artifact improvements, and release notes; enabled major user-facing features (revamped story mode, new music, enhanced multiplayer) and groundwork for cross-platform distribution. These changes reduce upgrade risk, improve player experience, and accelerate deployment and distribution.

Dec 1, 2025December 2025 monthly summary for SuperTux: Focused on delivering cross-platform stability, packaging readiness, editor usability, and targeted performance/cleanup improvements. The month saw significant strides in Linux session experience, build/distribution pipelines, and editor tooling, with a clear emphasis on business value—reliable releases, easier distribution, and better in-game UX. Key business-value driven outcomes include improved Linux session startup by defaulting to Wayland, enhanced packaging/CI support with Flatpak integration, and clearer packaging signals in CMake to improve dependency handling across environments. Overall impact: stronger cross-platform compatibility (Linux, BSDs, Ubuntu Touch considerations), more maintainable build pipelines, and more polished editor and rendering tooling, reducing post-release issues and accelerating future feature work. Technologies/skills demonstrated include: CMake packaging refinements and conditional build optimizations, Flatpak CI integration and workflow automation, Wayland/SDL integration for modern Linux desktops, editor UX/keyboard input handling, and viewport/window-management improvements, plus code cleanups and asset/icon management.

Sep 1, 2025Concise monthly summary for 2025-09 (SuperTux/supertux): Restored MovingSprite action-setting semantics to the previous behavior and improved code readability. The changes fixed an unintended behavioral drift while keeping the gameplay stable. Performed a targeted readability cleanup in spawn_explosion_sprites in moving_sprite.cpp without altering runtime behavior. These steps reduce regression risk, improve maintainability, and preserve expected user experience.
