Feb 1, 2026February 2026: Delivery focused on stability, compatibility, and gameplay quality for Geyser. Key outcomes include Bedrock 26.0 support with updated Bedrock-raknet/MCPL libraries and a revert to a stable Raknet release, startup hardening to prevent multiple initializations and improved server networking (channel open waits, timeouts, and NIO transport). Collision and physics refinements improve player interaction (copper lantern and chest collisions). Item handling enhancements enforce stack limits and provide fallbacks for protection values across legacy and modern mappings. Reliability and visibility improvements reduce unnecessary data transmission and improve visibility (red eyes on invisible spiders).

Sep 1, 2025Month: 2025-09 — GeyserMC/Geyser focused on delivering parity between Bedrock and Java gameplay, hardening UI reliability, and improving compatibility with older server versions. Key features delivered include a Block Breaking Mechanics Improvement (BlockBreakHandler and refined mining speed handling for Bedrock players) to provide smoother, more accurate block breaking. We added Default-Denied Permissions Configuration to give admins finer control by denying certain permissions by default with denies overriding grants. Dependency upgrades for compatibility (MCProtocollib and fabric-permissions-api) improve stability on older servers. Additional reliability work includes Localization Rendering Improvement with robust translation handling and a mapping fix, and Bedrock Update Notification Respect ensuring update notices are emitted only when enabled by server admins on Fabric/NeoForge. Major bugs fixed include Movement Collision and Position Correction Fixes, which revert unsafe previous changes to ensure correct player position updates and safer anti-cheat interaction; Form Handling Robustness and Safety to close inventories before showing new forms, log invalid actions, and kick players to prevent exploits; Flower Pot Interaction Visual Fix to resolve client-side visual discrepancies, and ensure inventory updates; Happy Ghast Movement Bug Fix removing NO_AI flag restriction to restore expected client-side movement; Skull Hash Validation and UI Cleanup with refined skull hash checks and UI handling; Legacy Color Handling Robustness to properly handle blank legacy color strings and apply defaults. Overall impact and accomplishments: These changes reduce gameplay disruptions, improve reliability across Bedrock/Java, enhance admin control and security, and broaden compatibility with older servers. Together, they deliver smoother gameplay, safer UI interactions, and a more robust, maintainable codebase that supports future feature work and performance goals. Technologies/skills demonstrated: Bedrock-Java parity enhancements, block breaking optimization, UI/UX reliability hardening, server configuration and permission model design, dependency management for compatibility, localization/internationalization handling, and rigorous UI/UX validation across platforms.

Jun 1, 2025June 2025 highlights: Implemented comprehensive 1.21.x compatibility updates, including early 1.21.6 changes, deprecating legacy 1.21.50/60, enabling 1.21.90 support, and gating UI elements (locator bar) to align with server readiness. Introduced ReceiptPacket system property to improve data reliability between Bedrock and Java sides. Hardened resource pack handling with improved console pack downloads, remote error handling, and avoided double-loading of the resource pack registry, reducing user-reported errors. Enabled forward commands with no permission to the backend server on Standalone/ViaProxy, expanding secure cross-server command execution. Resolved critical login and loading reliability issues ("unable to complete login" and Geyser-NeoForge loading) and updated Bedrock protocol library to the latest with Bedrock XUIDs in chat and player lists, plus 1.21.90 item/block palettes. These changes enhance upgrade readiness, user experience, and operator visibility while reducing incident latency for the most common support issues.
