FutureMUD Engine 2.0.0

Upgrade note: Back up your database, configuration, and world files before upgrading, and test the upgrade against a copy of your live database first. Engine 2.0.0 requires the .NET 10 runtime and MySQL 8.0. The Engine applies supported schema migrations during startup; do not point an older Engine build at a database after it has been upgraded to 2.0.0.

Release packages are framework-dependent, single-file archives for Windows x64, Linux x64, and Linux ARM64. Linux hosts may need to restore the executable bit after extraction with chmod +x MudSharp.

This is a very large release covering more than 1,200 commits since Engine 1.55.0. The list below groups small related fixes so it remains useful to players, builders, administrators, and operators.

Characters, Bodies, and Survival

• Added support for multiple simultaneous bodies belonging to one character identity, including focus switching, secondary-body lifecycle handling, reconnect and reboot persistence, admin creation controls, and clearer diagnostics.
• Added body-form provisioning, body backups, projection, cloning, and possession workflows, with tighter authority checks around spawning, seizing, and controlling character instances.
• Expanded racial hunger, thirst, satiation, and body-size scaling, including configurable racial limits and improved food-yield handling.
• Improved character creation knowledge selection, race and role setup, skill aliases, and recovery from incomplete or drifted starting data.
• Improved health strategies, wounds, infections, surgery interactions, offline healing, and the way injuries behave when a character changes bodies.
• Added configurable temperature consequences and expanded climate-aware item and body behaviour.
• Expanded drugs and dependence with more effect types, delivery vectors, stacking, withdrawal, offline progression, and safer cloning of drugs with optional metadata.
• Improved character, race, name, characteristic, tattoo, scar, disfigurement, hearing-profile, wear-profile, and description builders.
• Added optional email-registration bypass configuration for games that deliberately use a different account-approval workflow.
• Fixed a range of character load-order, corpse stripping, inventory transfer, and duplicate-item persistence problems.

Combat, Weapons, and Arenas

• Added complete sling and blowgun support using the normal ammunition system for damage, lodging, recovery, and poison delivery.
• Added configurable weapon poisons and delivery through eligible weapon and ammunition attacks.
• Added natural ranged attack families for spit, breath weapons, swooping breath attacks, buffeting attacks, and explosive natural attacks.
• Improved natural ranged attacks so authored range, item targets, scatter impacts, bodypart selection, area targets, penetration, and on-use scripts resolve consistently.
• Added builder support for fire profiles and liquid surface reactions, including damage, pain, stun, material tags, and extinguishing interactions on bodies and items.
• Expanded weapon and shield type support and improved seeded combat definitions used by new worlds.
• Added the Subdue combat strategy, including weapon-pressure and control behaviour suitable for guards, enforcers, and hostage-taking NPCs.
• Improved default combat settings, auxiliary combat actions, clinch and grapple choices, target loss, surrender, helpless-target handling, and NPC combat strategy selection.

• Fixed ambiguous, invalid, boundary, and long-horizon calendar and celestial calculations.

World Building, Rooms, and Pathfinding

• Added an incremental hierarchical pathfinding index for large worlds, with idle-slice rebuilding, live validation, automatic fallback, and diagnostics.
• Updated pathfinding when builders create or remove cells, exits, and portals so routes do not require a reboot to become correct.
• Improved actor-specific path suitability, closed and locked door handling, portal anchors, and route invalidation.

• Improved blocked-task throttling, scheduler coalescing, empty-work gating, and host lookups to reduce repeated or unnecessary work.
• Added builder and manager diagnostics that explain why work is blocked instead of silently retrying.
• Parent organisations, consolidated accounting, cross-currency finance, autonomous vehicle or animal work, and deeper native workflows remain post-2.0 extensions.

Deliberate 2.0 Boundaries

• Vehicle routes, timetables, coordinate movement, and moving room-scale interiors are not part of this release.
• AI Storyteller availability and quality depend on the external provider configured by each game.
• Advanced multi-body social identity, disguise, recognition, and campaign-specific legal policy remain builder and game-design concerns rather than automatic Engine rules.
• Some systems in this release are foundations that need game-specific content and builder configuration before players will encounter them.
