Added an null check in AIObjectiveManager.cs to avoid accessing removed resources
Use shuffledGaps instead of gapList to ensure update order requirement(already in master)
Updated parallelism count
Fixed parallelism count issue
Added SingleThreadWorker to handle single-thread related works
Fixed incorrect order when updating gaps
Potentially Fixed#39
Replaced direct access to GameMain.Server.ConnectedClients with array snapshots in multiple server-side classes to prevent concurrent modification issues during parallel updates. Also updated PhysicsBody and LevelTrigger to avoid static/shared state in parallel contexts, improving thread safety and reliability.
* Fixed? the cause of gap crashes. May require further monitor and check :(
* Fixed a bug that will cause the server stop responding
* Fixed (?) an issue causing a SetPosition() will crash the game
Removed CL release, Added manual dispatcher inputs
Implemented custom Lua converters for various thread-safe lists, ImmutableList, ImmutableHashSet, and ImmutableDictionary types. This allows seamless conversion between C# collections and Lua tables, improving Lua scripting integration with these collection types.
Changed ResetReceivedEvents from partial to regular method in EntitySpawner to ensure proper event queue clearing. Updated Level.cs to clear tempCellsLocal instead of tempCells, addressing potential issues with thread-local storage.
Replaced instance fields with ThreadLocal collections in Hull.GetConnectedHulls and Level.GetCells to ensure thread safety during parallel updates. Methods now return copies of the collections to prevent concurrent modification issues.
Refactors event, entity, and physics management to use thread-safe and lock-free data structures (Immutable collections, ConcurrentQueue, ConcurrentDictionary, Channel) for improved concurrency and performance. Replaces O(n) queue lookups with O(1) set/dictionary checks, ensures atomic updates for shared state, and optimizes queue draining and deferred action processing. Updates related code to use new APIs and patterns, and adds documentation for thread safety and workflow.
Fixed an issue causing gap.update crashes the game(engine issue)
Fixed an potential issue that on MacOS we cannot get core count and cause MaxDegreeOfParallelism will be set to 0. Now if we cant get that number we simply use a fixed 16 instead

Replaced static entity lists (e.g., HullList, GapList, MapEntityList, etc.) with thread-safe copy-on-write wrappers to improve concurrency and prevent race conditions. Updated usages and related methods to support the new thread-safe collections, ensuring atomic operations and lock-free reads throughout the codebase.
Eliminated redundant locks and related comments in EntitySpawner and Entity classes, simplifying the spawn and remove queue handling. Also removed outdated comments in GameScreen regarding thread safety. These changes assume entity spawning and removal are no longer performed from multiple threads, improving code clarity and maintainability.
Refactored multiple components to defer Farseer physics transform operations using PhysicsBodyQueue, preventing unsafe calls from parallel contexts. This change addresses thread safety issues with Farseer's DynamicTree and ensures transforms are executed in a safe context. Also increased the spawn amount limit in DebugConsole from 100 to 100000.
Refactored SoundChannel and SoundManager to use explicit locking for OpenAL operations and channel assignment, preventing race conditions during parallel sound playback. Added thread-local stacks in DynamicTree to ensure thread safety during parallel physics queries and raycasts. These changes address concurrency issues when sounds or physics queries are triggered from multiple threads.
Introduces a thread-safe queue for deferring physics operations (such as body creation and transforms) to the main thread, ensuring Farseer Physics is not accessed from parallel contexts. Updates Holdable, Item, MapEntity, and GameScreen to use the new PhysicsBodyQueue for safe physics operations during parallel updates, and refactors PhysicsBodyQueue to support general deferred physics actions.
Introduces PhysicsBodyQueue to safely defer physics body creation to the main thread, addressing thread-safety issues with Farseer Physics during parallel updates. Updates LevelResource, TriggerComponent, BallastFloraBehavior, and MapEntity to use the queue for all physics body creation and refresh operations, ensuring they are processed outside of parallel loops. Also adds cleanup of the queue at round end.
Refactored various static and instance collections to use [ThreadStatic], ThreadLocal, or local variables to prevent concurrent modification issues during parallel updates. This affects status effect targets, affliction lists, damage modifiers, and cached data in Character, CharacterHealth, Limb, Explosion, Hull, Submarine, and ToolBox classes. Also replaced Dictionary caches with ConcurrentDictionary where appropriate for thread safety.
Replaces direct increments of LastClientListUpdateID with a thread-safe IncrementLastClientListUpdateID method and uses Interlocked for atomic operations. Refactors EntitySpawner to lock access to the spawn/remove queue for thread safety. Updates INetSerializableStruct to use concurrent collections for cached variables and type behaviors, improving thread safety in networking code.
Refactored various collections (lists, dictionaries, queues, and caches) in AI, character, animation, and item component systems to use thread-safe patterns and concurrent data structures. This includes introducing copy-on-write wrappers, ConcurrentDictionary, ConcurrentQueue, and ThreadLocal where appropriate to ensure safe concurrent access and mutation, improving stability in multi-threaded scenarios.
Add a marker to help distinguish EP from other SV Executables
Fixed a "Failed to copy object. Source is null." introduced by last update
Uses dynamic ThreadCount instead of fixed 16
Re-Removed most PF support
Re-Parallelzed Level update and Character Update(a conflict warning will be issued
Replaced static lists and dictionaries with thread-safe ConcurrentDictionary or ThreadLocal collections for various item components and systems. Updated all relevant code to use snapshots (ToArray, ToList) for safe iteration, and added helper methods for marking and clearing changed connections. These changes improve thread safety and prevent potential concurrency issues in multi-threaded scenarios.
Replaces static Item.ItemList and related collections with thread-safe data structures using ConcurrentDictionary and ImmutableHashSet. Adds thread-safe helpers for marking items for deconstruction and managing item lists. Updates all usages of Item.ItemList and DeconstructItems to use new APIs, improving performance and safety in multi-threaded contexts. Also refactors MeleeWeapon and Projectile impact queues to use ConcurrentQueue, and updates related logic throughout the codebase.
