Month: 2026-03 — Canary repository (opentibiabr/canary). Focused on reliability, gameplay balance, and observability, delivering user-visible features alongside critical fixes and data integrity improvements. Key features delivered: - Logging system enhancement: SPDLOG formatting (commit 563c5fdc42ae4a4ddd75899d90a671c6146777b0). Safer, more flexible log messages with standard fmt-style formatting, improving maintainability and troubleshooting. - Inventory management enhancement: Loot pouch reordering and validation (commit 3acfcd3ed3887e80d1fa6db5228e934d7feb79d8). Enables reorganization within store inboxes, with stricter validation and adherence to transfer restrictions to prevent invalid moves; includes related style and minor formatting tweaks. - Monk quest bonus integration into Wheel of Destiny (commit 0bdc79068f16d9b20d2490356f92aebc37fe8e6a). Adds Monk quest bonus to server/client point calculations and validates completion, enhancing player progression tracking and rewards consistency. Major bugs fixed: - Summoned Creatures Healing Fix in Combat (commit b334dfe4444cc237ea831121f74e4fd8516c541c). Corrected healing interaction so summoned creatures heal only when the caster is not the target, preventing unintended self-healing and improving combat balance. Overall impact and accomplishments: - Strengthened gameplay fairness and reliability through corrected combat healing behavior and robust validation on item transfers. - Improved observability and maintainability with standardized logging, aiding faster incident response. - Enhanced player engagement by delivering new Monk quest bonuses and ensuring accurate points calculation across server and client. Technologies/skills demonstrated: - SPDLOG formatting and safe log message construction; logging hygiene improvements. - Server-client data synchronization for dynamic bonus calculation. - Robust inventory validation logic and transfer rule enforcement. - Quest-state validation and storage-backed progress tracking. Business value: - Reduced gameplay friction and potential exploitation by clarifying combat healing rules and transfer validations. - Improved developer efficiency via safer logging and clearer observability for debugging and performance monitoring. - Increased player satisfaction and retention through timely quest bonuses and accurate rewards."
