### Other

* `Entity<T>` methods were marked as `readonly` as appropriate.


## 258.0.1

### Bugfixes

* Fix static physics bodies not generating contacts if they spawn onto sleeping bodies.


## 258.0.0

### Breaking changes

* `IMarkupTag` and related methods in `MarkupTagManager` have been obsoleted and should be replaced with the new `IMarkupTagHandler` interface. Various engine tags (e.g., `BoldTag`, `ColorTag`, etc) no longer implement the old interface.

### New features

### Bugfixes

* OutputPanel and RichTextLabel now remove controls associated with rich text tags when the text is updated.
* Fix `SpriteComponent.Visible` datafield not being read from yaml.
* Fix container state handling not forcing inserts.

### Other

* `SpriteSystem.LayerMapReserve()` no longer throws an exception if the specified layer already exists. This makes it behave like the obsoleted `SpriteComponent.LayerMapReserveBlank()`.


## 257.0.2

### Bugfixes

* Fix unshaded sprite layers not rendering correctly.


## 257.0.1

### Bugfixes

* Fix sprite layer bounding box calculations. This was causing various sprite rendering & render-tree lookup issues.


## 257.0.0

### Breaking changes

* The client will now automatically pause any entities that leave their PVS range.
* Contacts for terminating entities no longer raise wake events.

### New features

* Added `IPrototypeManager.IsIgnored()` for checking whether a given prototype kind has been marked as ignored via `RegisterIgnore()`.
* Added `PoolManager` & `TestPair` classes to `Robust.UnitTesting`. These classes make it easier to create & use pooled server/client instance pairs in integration tests.
* Catch NotYamlSerializable DataFields with an analyzer.
* Optimized RSI preloading and texture atlas creation.

### Bugfixes

* Fix clients unintentionally un-pausing paused entities that re-enter pvs range

### Other

* Several SpriteComponent methods have been marked as obsolete, and should be replaced with new methods in SpriteSystem.
* Rotation events no longer check for grid traversal.


## 256.0.0

### Breaking changes

* Moved AsNullable extension methods to the Entity struct.

### New features

* Add DevWindow tab to show all loaded textures.
* Add Vector2i / bitmask converfsion helpers.
* Allow texture preload to be skipped for some textures.

### Other

* Make ItemList not run deselection callback on all items if they aren't selected.
* Cleanup warnings for CS0649 & CS0414.

### Internal

* Move PointLight component states to shared.


## 255.1.0

### New features

* The client localisation manager now supports hot-reloading ftl files.
* TransformSystem can now raise `GridUidChangedEvent` and `MapUidChangedEvent` when a entity's grid or map changes. This event is only raised if the `ExtraTransformEvents` metadata flag is enabled.

### Bugfixes

* Fixed a server crash due to a `NullReferenceException` in PVS system when a player's local entity is also one of their view subscriptions.
* Fix CompileRobustXamlTask for benchmarks.
* .ftl files will now hot reload.
* Fix placementmanager sometimes not clearing.

### Other

* Container events are now documented.


## 255.0.0

### Breaking changes

* `RobustIntegrationTest` now pools server/client instances by default. If a custom settings class is provided, it will still disable pooling unless explicitly enabled.
  * Server/Client instances that are returned to the pool should be disconnected. This might require you to update some tests.
  * Pooled instances also require you to use `RobustIntegrationTest` methods like `WaitPost()` to ensure the correct thread is used.

### Bugfixes

* Fix `EntityDeserializer` improperly setting entity lifestages when loading a post-mapinit map.
* Fix `EntityManager.PredictedDeleteEntity()` not deleting pure client-side entities.
* Fix grid fixtures using a locale dependent id. This could cause some clients to crash/freeze when connected to a server with a different locale.

### Other

* Add logic to block cycles in master MIDI renderers, which could otherwise cause client freezes.


## 254.1.0

### New features

* Add CC ND licences to the RGA validator.
* Add entity spawn prediction and entity deletion prediction. This is currently limited as you are unable to predict interactions with these entities. These are done via the new methods prefixed with "Predicted". You can also manually flag an entity as a predicted spawn with the `FlagPredicted` method which will clean it up when prediction is reset.

### Bugfixes

* Fix tile edge rendering for neighbor tiles being the same priority.

### Other

* Fix SpawnAttachedTo's system proxy method not the rotation arg like EntityManager.


## 254.0.0

### Breaking changes

* Yaml mappings/dictionaries now only support string keys instead of generic nodes
  * Several MappingDataNode method arguments or return values now use strings instead of a DataNode object
  * The MappingDataNode class has various helper methods that still accept a ValueDataNode, but these methods are marked as obsolete and may be removed in the future.
  * yaml validators should use `MappingDataNode.GetKeyNode()` when validating mapping keys, so that errors can print node start & end information
* ValueTuple yaml serialization has changed
  * Previously they would get serialized into a single mapping with one entry (i.e., `{foo : bar }`)
  * Now they serialize into a sequence (i.e., `[foo, bar]`)
  * The ValueTuple serializer will still try to read mappings, but due to the MappingDataNode this may fail if the previously serialized "key" can't be read as a simple string

### New features

* Add cvar to disable tile edges.
* Add GetContainingContainers method to ContainerSystem to recursively get containers upwards on an entity.

### Internal

* Make component lifecycle methods use generics.


## 253.0.0

### New features

* Add a new `SerializationManager.PushComposition()` overload that takes in a single parent instead of an array of parents.
* `BoundUserInterfaceMessageAttempt` once again gets raised as a broadcast event, in addition to being directed.
  * This effectively reverts the breaking part of the changes made in v252.0.0
* Fix CreateDistanceJoint using an int instead of a float for minimum distance.

### Bugfixes

* Fix deferred component removal not setting the component's life stage to `ComponentLifeStage.Stopped` if the component has not yet been initialised.
* Fix some `EntitySystem.Resolve()` overloads not respecting the optional `logMissing` argument.
* Fix screen-space overlays not being useable without first initializing/starting entity manager & systems
* ItemList is now significantly optimized. VV's `AddComponent` window in particular should be much faster.
* Fix some more MapValidator fields.
* Fix popup text overflowing the sides of the screen.
* Improve location reporting for non-writeable datafields via analyzer.

### Other

* TestPoint now uses generics rather than IPhysShape directly.


## 252.0.0

### Breaking changes

* BoundUserInterfaceMessageAttempt is raised directed against entities and no longer broadcast.


## 251.0.0

### Breaking changes

* Localization is now separate between client and server and is handled via cvar.
* Contacting entities no longer can be disabled for CollisionWake to avoid destroying the contacts unnecessarily.

### New features

* Added `DirectionExtensions.AllDirections`, which contains a list of all `Direction`s for easy enumeration.
* Add ForbidLiteralAttribute.
* Log late MsgEntity again.
* Show entity name in `physics shapeinfo` output.
* Make SubscribeLocalEvent not require EntityEventArgs.
* Add autocomplete to `tp` command.
* Add button to jump to live chat when scrolled up.
* Add autocomplete to `savemap` and `savegrid`.

### Bugfixes

* Fix velocity not re-applying correctly on re-parenting.
* Fix Equatable on FormattedMessage.
* Fix SharedTransformSystem methods logging errors on resolves.

### Other

* Significantly optimized tile edge rendering.

### Internal

* Remove duplicate GetMassData method.
* Inline manifold points for physics.


## 250.0.0

### Breaking changes

* The default shader now interprets negative color modulation as a flag that indicates that the light map should be ignored.
  * This can be used to avoid having to change the light map texture, thus reducing draw batches.
  * Sprite layers that are set to use the "unshaded" shader prototype now use this.
  * Any fragment shaders that previously the `VtxModulate` colour modulation variable should instead use the new `MODULATE` variable, as the former may now contain negative values.

### New features

* Add OtherBody API to contacts.
* Make FormattedMessages Equatable.
* AnimationCompletionEvent now has the AnimationPlayerComponent.
* Add entity description as a tooltip on the entity spawn panel.

### Bugfixes

* Fix serialization source generator breaking if a class has two partial locations.
* Fix map saving throwing a `DirectoryNotFoundException` when given a path with a non-existent directory. Now it once again creates any missing directories.
* Fix map loading taking a significant time due to MappingDataNode.Equals calls being slow.

### Other

* Add Pure to some Angle methods.

### Internal

* Cleanup some warnings in classes.


## 249.0.0

### Breaking changes

* Layer is now read-only on VisibilityComponent and isn't serialized.

### New features

* Added a debug overlay for the linear and angular velocity of all entities on the screen. Use the `showvel` and `showangvel` commands to toggle it.
* Add a GetWorldManifold overload that doesn't require a span of points.
* Added a GetVisMaskEvent. Calling `RefreshVisibilityMask` will raise it and subscribers can update the vismask via the event rather than subscribers having to each manually try and handle the vismask directly.

### Bugfixes

* `BoxContainer` no longer causes stretching children to go below their minimum size.
* Fix lights on other grids getting clipped due to ignoring the light range cvar.
* Fix the `showvelocities` command.
* Fix the DirtyFields overload not being sandbox safe for content.

### Internal

* Polygon vertices are now inlined with FixedArray8 and a separate SlimPolygon using FixedArray4 for hot paths rather than using pooled arrays.


## 248.0.2

### Bugfixes

* Don't throw in overlay rendering if MapUid not found.

### Internal

* Reduce EntityManager.IsDefault allocations.


## 248.0.1

### Bugfixes

* Bump ImageSharp version.
* Fix instances of NaN gain for audio where a negative-infinity value is being used for volume.


## 248.0.0

### Breaking changes

* Use `Entity<MapGridComponent>` for TileChangedEvent instead of EntityUid.
* Audio files are no longer tempo perfect when being played if the offset is small. At some point in the future an AudioParams bool is likely to be added to enforce this.
* MoveProxy method args got changed in the B2DynamicTree update.
* ResPath will now assert in debug if you pass in an invalid path containing the non-standardized directory separator.

### New features

* Added a new `MapLoaderSystem.TryLoadGrid()` override that loads a grid onto a newly created map.
* Added a CVar for the endbuffer for audio. If an audio file will play below this length (for PVS reasons) it will be ignored.
* Added Regex.Count + StringBuilder.Chars setter to the sandbox.
* Added a public API for PhysicsHull.
* Made MapLoader log more helpful.
* Add TryLoadGrid override that also creates a map at the same time.
* Updated B2Dynamictree to the latest Box2D V3 version.
* Added SetItems to ItemList control to set items without removing the existing ones.
* Shaders, textures, and audio will now hot reload automatically to varying degrees. Also added IReloadManager to handle watching for file-system changes and relaying events.
* Wrap BUI disposes in a try-catch in case of exceptions.


### Bugfixes

* Fix some instances of invalid PlaybackPositions being set.
* Play audio from the start of a file if it's only just come into PVS range / had its state handled.
* Fix TryCopyComponents.
* Use shell.WriteError if TryLoad fails for mapping commands.
* Fix UI control position saving causing exceptions where the entity is cleaned-up alongside a state change.
* Fix Map NetId completions.
* Fix some ResPath calls using the wrong paths.

### Internal

* Remove some unused local variables and the associated warnings.


## 247.2.0

### New features

* Added functions for copying components to `IEntityManager` and `EntitySystem`.
* Sound played from sound collections is now sent as "collection ID + index" over the network instead of the final filename.
  * This enables integration of future accessibility systems.
  * Added a new `ResolvedSoundSpecifier` to represent played sounds. Methods that previously took a filename now take a `ResolvedSoundSpecifier`, with an implicit cast from string being interpreted as a raw filename.
* `VisibilitySystem` has been made accessible to shared as `SharedVisibilitySystem`.
* `ScrollContainer` now has properties exposing `Value` and `ValueTarget` on its internal scroll bars.

### Bugfixes

* Fix prototype hot reload crashing when adding a new component already exists on an entity.
* Fix maps failing to save in some cases related to tilemap IDs.
* Fix `Regex.Escape(string)` not being available in sandbox.
* Prototypes that parent themselves directly won't cause the game to hang on an infinite loop anymore.
* Fixed disconnecting during a connection attempt leaving the client stuck in a phantom state.

### Internal

* More warning cleanup.

## 247.1.0

### New features

* Added support for `Color[]` shader uniforms
* Added optional minimumDistance parameter to `SharedJointSystem.CreateDistanceJoint()`

### Bugfixes

* Fixed `EntitySystem.DirtyFields()` not actually marking fields as dirty.

### Other

* Updated the Yamale map file format validator to support v7 map/grid files.


## 247.0.0

### Breaking changes

* `ITileDefinitionManager.AssignAlias` and general tile alias functionality has been removed. `TileAliasPrototype` still exist, but are only used during entity deserialization.
* `IMapManager.AddUninitializedMap` has been removed. Use the map-init options on `CreateMap()` instead.
* Re-using a MapId will now log a warning. This may cause some integration tests to fail if they are configured to fail
  when warnings are logged.
* The minimum supported map format / version has been increased from 2 to 3.
* The server-side `MapLoaderSystem` and associated classes & structs has been moved to `Robust.Shared`, and has been significantly modified.
  * The `TryLoad` and `Save` methods have been replaced with grid, map, generic entity variants. I.e, `SaveGrid`, `SaveMap`, and `SaveEntities`.
  * Most of the serialization logic and methods have been moved out of `MapLoaderSystem` and into new `EntitySerializer`
    and `EntityDeserializer` classes, which also replace the old `MapSerializationContext`.
  * The `MapLoadOptions` class has been split into `MapLoadOptions`, `SerializationOptions`, and `DeserializationOptions`
    structs.
* The interaction between PVS overrides and visibility masks / layers have changed:
  * Any forced entities (i.e., `PvsOverrideSystem.AddForceSend()`) now ignore visibility masks.
  * Any global & session overrides (`PvsOverrideSystem.AddGlobalOverride()` & `PvsOverrideSystem.AddSessionOverride()`) now respect visibility masks.
  * Entities added via the `ExpandPvsEvent` respect visibility masks.
  * The mask used for any global/session overrides can be modified via `ExpandPvsEvent.Mask`.
* Toolshed Changes:
  * The signature of Toolshed type parsers have changed. Instead of taking in an optional command argument name string, they now take in a `CommandArgument` struct.
  * Toolshed commands can no longer contain a '|', as this symbol is now used for explicitly piping the output of one command to another. command pipes. The existing `|` and '|~' commands have been renamed to `bitor` and `bitnotor`.
  * Semicolon terminated command blocks in toolshed commands no longer return anything. I.e., `i { i 2 ; }` is no longer a valid command, as the block has no return value.

### New features

* The current map format/version has increased from 6 to 7 and now contains more information to try support serialization of maps with null-space entities and full game saves.
* `IEntitySystemManager` now provides access to the system `IDependencyCollection`.
* Toolshed commands now support optional and `params T[]` arguments. optional / variable length commands can be terminated using ';' or '|'.

### Bugfixes

* Fixed entity deserialization for components with a data fields that have a AlwaysPushInheritance Attribute
* Audio entities attached to invisible / masked entities should no longer be able to temporarily make those entities visible to all players.
* The map-like Toolshed commands now work when a collection is piped in.
* Fixed a bug in toolshed that could cause it to preferentially use the incorrect command implementation.
  * E.g., passing a concrete enumerable type would previously use the command implementation that takes in an unconstrained generic parameter `T` instead of a dedicated `IEnumeerable<T>` implementation.

### Other

* `MapChangedEvent` has been marked as obsolete, and should be replaced with `MapCreatedEvent` and `MapRemovedEvent.
* The default auto-completion hint for Toolshed commands have been changed and somewhat standardized. Most parsers should now generate a hint of the form:
  * `<name (Type)>` for mandatory arguments
  * `[name (Type)]` for optional arguments
  * `[name (Type)]...` for variable length arguments (i.e., for `params T[]`)


## 246.0.0

### Breaking changes

* The fixes to renderer state may have inadvertantly broken some rendering code that relied upon the old behavior.
* TileRenderFlag has been removed and now it's just a byte flag on the tile for content usage.

### New features

* Add BeforeLighting overlay draw space for overlays that need to draw directly to lighting and want to do it immediately beforehand.
* Change BlurLights to BlurRenderTarget and make it public for content usage.
* Add ContentFlag to tiles for content-flag usage.
* Add a basic mix shader for doing canvas blends.
* Add GetClearColorEvent for content to override the clear color behavior.

* Fix the pooled polygons using incorrect vertices for EntityLookup and MapManager.

### Internal

* Avoid normalizing angles constructed from vectors.


## 242.0.0

### Breaking changes

* The order in which the client initialises networked entities has changed. It will now always apply component states, initialise, and start an entity's parent before processing any children. This might break anything that was relying on the old behaviour where all component states were applied before any entities were initialised & started.
* `IClydeViewport` overlay rendering methods now take in an `IRenderHandle` instead of a world/screen handle.
* The `OverlayDrawArgs` struct now has an internal constructor.

### New features

* Controls can now be manually restyled via `Control.InvalidateStyleSheet()` and `Control.DoStyleUpdate()`
* Added `IUserInterfaceManager.RenderControl()` for manually drawing controls.
* `OverlayDrawArgs` struct now has an `IRenderHandle` field such that overlays can use the new `RenderControl()` methods.
* TileSpawnWindow will now take focus when opened.

### Bugfixes

* Fixed a client-side bug where `TransformComponent.GridUid` does not get set properly when an existing entity is attached to a new entity outside of the player's PVS range.
* EntityPrototypeView will only create entities when it's on the UI tree and not when the prototype is set.
* Make CollisionWake not log errors if it can't resolve.

### Other

* Replace IPhysShape API with generics on IMapManager and EntityLookupSystem.

### Internal

* Significantly reduce allocations for Box2 / Box2Rotated queries.


## 241.0.0

* Added `EntityManager.DirtyFields()`, which allows components with delta states to simultaneously mark several fields as dirty at the same time.
* Add `CloserUserUIs<T>` to close keys of a specific key.

### Bugfixes

* Fixed `RaisePredictiveEvent()` not properly re-raising events during prediction for event handlers that did not take an `EntitySessionEventArgs` argument.
* BUI openings are now deferred to avoid having slight desync between deferred closes and opens occurring in the same tick.


## 240.1.2


## 240.1.1

### Bugfixes

* Fixed one of the `IOverlayManager.RemoveOverlay` overrides not fully removing the overlay.


## 240.1.0

### New features

* Added an `AsNullable` extension method for converting an `Entity<T>` into an `Entity<T?>`

### Bugfixes

* Fixed an exception in `PhysicsSystem.DestroyContacts()` that could result in entities getting stuck with broken physics.

### Other

* `GamePrototypeLoadManager` will now send all uploaded prototypes to connecting players in a single `GamePrototypeLoadMessage`, as opposed to one message per upload.


## 240.0.1

### Bugfixes

* Fixed `SharedBroadphaseSystem.GetBroadphases()` not returning the map itself, which was causing physics to not work properly off-grid.


## 240.0.0

### Breaking changes

* `ComponentRegistry` no longer implements `ISerializationContext`
* Tickrate values are now `ushort`, allowing them to go up to 65535.

### New features

* Console completion options now have new flags for preventing suggestions from being escaped or quoted.
* Added `ILocalizationManager.HasCulture()`.
* Static `EntProtoId<T>` fields are now validated to exist.

### Bugfixes

* Fixed a state handling bug in replays, which was causing exceptions to be thrown when applying delta states.

### Other

* Reduced amount of `DynamicMethod`s used by serialization system. This should improve performance somewhat.

### Internal

* Avoided sorting overlays every render frame.
* Various clean up to grid fixture code/adding asserts.

## 239.0.1

### Bugfixes

* Fix logging of received packets with `net.packet` logging level.
* Downgrade `VorbisPizza` to fix audio playback for systems without AVX2 support.

### Other

* Improved performance of some Roslyn analyzers and source generators, which should significantly improve compile times and IDE performance.


## 239.0.0

### Breaking changes

* Robust now uses **.NET 9**.
* `ISerializationManager` will now log errors if it encounters `Entity<T>` data-fields.
  * To be clear, this has never been supported and is not really a breaking change, but this will likely require manual intervention to prevent tests from failing.
* `IClyde.TextInputSetRect`, `TextInputStart` and `TextInputStop` have been moved to be on `IClydeWindow`.
* Updated various NuGet dependencies and removed some other ones, of note:
  * `FastAccessors`, which is a transitive dep we never used, is now gone. It might have snuck into some `using` statement thanks to your IDE, and those will now fail to compile. Remove them.
  * NUnit `Is.EqualTo(default)` seems to have ambiguous overload resolution in some cases now, this can be fixed by using an explicit `default(type)` syntax.
  * This also fixed various false-positive warnings reported by NuGet.

### New features

* Added `MockInterfaces.MakeConfigurationManager` for creating functional configuration managers for unit test mocking.
* Added `ISawmill.IsLogLevelEnabled()` to avoid doing expensive verbose logging operations when not necessary.
* ``string[] Split(System.ReadOnlySpan`1<char>)`` is now available in sandbox.

### Bugfixes

* Fixed auto-generated component delta-states not raising `AfterAutoHandleStateEvent`
* Fixed auto-generated component delta-states improperly implementing `IComponentDeltaState` methods. May have caused bugs in replays.
* Fixed `Robust.Client.WebView` on the launcher via a new release.
* Fixed an exception that could occur when saving a map that had tiles migrated by alias.

### Other

* The `loglevel` command now properly shows the "`null`" log level that resets the level to inheriting from parent. This was already supported by it, but the completions didn't list it.

### Internal

* Experimental SDL2 windowing backend has been replaced with SDL3. SDL3 backend is also more feature-complete, though it is still not in use.
* Updated CEF used by Robust.Client.WebView to 131.3.5.

## 238.0.1

### Bugfixes

* Fixed source generation for auto-networked EntityUid Dictionaries missing a semicolon
* Fixed PlacementManager using the wrong coordinates when deleting entities in an area.


## 238.0.0

### Breaking changes

* Some toolshed command syntax/parsing has changed slightly, and several toolshed related classes and interfaces have changed significantly, including ToolshedManager, type parsers, invocation contexts, and parser contexts. For more detail see the the description of PR #5455

* Added `DAT-OBJ()` localization function, for the dative case in certain languages.
* Client builds for FreeBSD are now made.
* Added `FormattedMessage.TrimEnd()`.
* Added Toolshed `with` for `ProtoId<T>`.

### Bugfixes

* Fix `UniqueIndex<,>.RemoveRange()` and`UniqueIndexHkm<,>.RemoveRange()` clearing the whole set instead of just removing the specified values.
* Avoid server crashes on some weird console setups (notably Pterodactyl).
* Avoid unhandled exceptions during server shutdown getting swallowed due logging into a disposed logger.
* Fix sandbox definitions for `Regex` functions returning `MatchCollection`.
* Fix minor layout bugs with `SplitContainer` and `BoxContainer`.

### Other

* Changed how multi-window rendering presents to the screen with a new CVar `display.thread_unlock_before_swap`. This is an experiment to see if it solves some synchronization issues.
* View Variables no longer clears the window on refresh while waiting on response from server.
* `SpinBox` buttons now have a `+` prefix for the positive ones.
* Improve Toolshed type intersection mechanism

### Internal

### New features

* The game server's `/update` endpoint now supports passing more information on why an update is available.
  * This information is accessible via `IWatchdogApi.RestartRequested`.
  * Information can be specified by passing a JSON object with a `Reason` code and `Message` field.
* Added an "Erase" button to the tile spawn menu.
* Added `OSWindow.Create()`, which allows OS windows to be created & initialised without immediately opening/showing them.

### Other

* Made `WatchdogApi` and some members of `IWatchdogApi` private. These symbols should never have been accessed by content.


## 236.1.0

### New features

* `RequiredMemberAttribute` and `SetsRequiredMembersAttribute` have been added to the sandbox whitelist. I.e., you can now use the `required` keyword in client/shared code.

## 223.0.0

### Breaking changes

* The `ComponentState` class is now abstract. Networked components that don't have state information now just return a null state.

  - Interface data is now stored via key rather than as a flat list which is a breaking change for YAML.
  - BoundUserInterfaces can now be completely handled via Shared code. Existing Server-side callers will behave similarly to before.

* TransformSystem.SetWorldPosition and SetWorldPositionRotation will now also perform parent updates as necessary. Previously it would just set the entity's LocalPosition which may break if they were inside of a container. Now they will be removed from their container and TryFindGridAt will run to correctly parent them to the new position. If the old functionality is desired then you can use GetInvWorldMatrix to update the LocalPosition (bearing in mind containers may prevent this).

* Add AddUi to the shared UI system.

### Bugfixes

* Fix the first measure of ScrollContainer bars.


## 216.0.0

### Breaking changes

Instead of limiting the range at which all entities are sent to a player, it now extends the range at which high priorities can be sent. The default value of this new cvar is 32.5, which is larger than the default `net.pvs_range` value of 25.

### New features

* You can now specify a component to not be saved to map files with `[UnsavedComponent]`.
* Added `ITileDefinitionManager.TryGetDefinition`.

* There is now a built-in type serializer for `DateTime`, so you can put `DateTime`s in your data fields.
* `System.Text.Unicode.UnicodeRange` and `UnicodeRanges` are now available in the sandbox.

### Bugfixes

* UI drawing now properly accounts for a control's draw routine potentially mangling the current matrix.

* Add shape versions of queries for both EntityLookup and MapManager.

### Bugfixes

* Fix PVS full state updates not clearing session entities and causing exceptions.

### Other

* Integration tests now run `NetMessage`s through serialization rather than passing the objects between client and server. This causes tests that missed `[NetSerializer]` attributes on any objects that need them to fail.

### Internal

* Remove a lot of duplicate code internally from EntityLookup and MapManager.


## 206.0.0

### Breaking changes

* tpto will teleport you to physics-center instead of transform center instead.

## 197.0.0

### Breaking changes

* PvsOverrideSystem has been reworked:
  * Session and global overrides now default to always being recursive (i.e., sending all children).
  * Session & global overrides will always respect a client's PVS budgets.
  * Entities with an override will now still be sent in the same way as other entities if they are within a player's view. If you want to prevent them from being sent, you need to use visibility masks.
  * Entities can have more than one kind of override (i.e., multiple sessions).

### New features

* Added a `PvsSize ` field to `EyeComponent`, which can be used to modify the PVS range of an eye.
* Added a new `NetLowLodRange` cvar for reducing the number of distant entities that get sent to a player. If a PVS chunk is beyond this range (but still within PVS range), then only high-priority entities on that chunk will get sent.
* Added a new metadata flag for tagging an entity as a "high prority" entity that should get sent even on distant chunks. This only works for entities that are directly attached to a grid or map. This is currently used by lights & occluders.

### Other

* PVS has been reworked again, and should hopefully be noticeable faster.
* PVS now prioritizes sending chunks that are closer to a player's eyes.


## 196.0.0

### Other

* Drastically improved startup time by running prototype loading in parallel.
  * `AfterDeserialization` hooks are still ran on the main thread during load to avoid issues.
* Various systems in the serialization system such as `SerializationManager` or `ReflectionManager` have had various methods made thread safe.
* `TileAliasPrototype` no longer has a load priority set.
* Straightened out terminology in prototypes: to refer to the type of a prototype (e.g. `EntityPrototype` itself), use "kind".
  * This was previously mixed between "type" and "variant".

### Internal

* `SpanSplitExtensions` has been taken behind the shed for being horrifically wrong unsafe code that should never have been entered into a keyboard ever. A simpler helper method replaces its use in `Box2Serializer`.
* `PrototypeManager.cs` has been split apart into multiple files.

## 0.73.0.0

### Breaking changes

* The entity lookup flag `LookupFlags.Anchored` has been replaced with `LookupFlags.Static`.
* We are now using **.NET 7**.
* `IDependencyCollection`/`IoCManager` `RegisterInstance` does not automatically add the instance to object graph, so `BuildGraph()` must now be called to see the new instances.
  * `deferInject` parameteres have been removed.

### New features

* The server will now check for any unknown CVars at startup, to possibly locate typos in your config file.
* `IDependencyCollection` is now thread safe.

### Bugfixes

### Bugfixes

* `csi` doesn't throw a `NullReferenceException` anymore.

### Other

* The `game.maxplayers` CVar has been deprecated in favor of the new `net.max_connections` CVar. Functionality is the same, just renamed to avoid confusion. The old CVar still exists, so if `game.maxplayers` is set it will be preferred over the new one.
* The new default for `net.max_connections` is 256.
* Debug monitors (F3) now have margin between them.
* F3 (clyde monitor) now lists the windowing API and version in use.
* Added system monitor to F3 with various info like OS version, .NET runtime version, etc...

## 0.70.0.0

### New features

* `game.desc` CVar for a server description to show in the launcher.
* New system for exposing links to e.g. a Discord in the launcher.
  * The engine does not have a built-in method for configuring these, but it does now have a `StatusHostHelpers.AddLink` method to correctly format these from content. The idea is that content wires the types of links (with icon names) up itself via `IStatusHost.OnInfoRequest`.
  * See also [the HTTP API documentation](https://docs.spacestation14.io/en/engine/http-api) for reference.
* `GameShared` now has a `Dependencies` property to allow access to the game's `IDependencyCollection`. This makes it possible to avoid using static `IoCManager` in `EntryPoint`-type content code.

* `IClientStateManager` now has a `PartialStateReset()` function to make it easier for content to rewind to previous game states.
* Added `IClientNetManager.DispatchLocalNetMessage()`, which allows a client to raise a local message that triggers networked event subscriptions.

### Bugfixes

* `IPlayerSession.OnConnect()` now actually gets called when players connect.
* `MapLoaderSystem.TryLoad(.., out rootUids)` now properly only returns entities parented to the map.

### Other

* Invalid placement types for the entity spawn menu now log warnings.
* Slightly improved sprite y-sorting performance.

### Internal

* The current physics map that an entity is on is now cached in the transform component alongside other cached broadphase data. This helps to fix some broadphase/lookup bugs.

* The `grids` yaml node on map files is deprecated and has been merged onto MapGridComponent. Loading maps is backwards compatible for now but is subject to change in future. Saving maps will save in the new format.


## 0.66.0.0

### Breaking changes

* General cleanup to `Tools/version.py`.

## 0.64.1.0

### Bugfixes

* Word-wrapping in `OutputPanel` and `RichTextLabel` has been fixed.

## 0.64.0.0

### Breaking changes

* IMapLoader has been refactored into MapLoaderSystem. The API is similar for now but is subject to change in the future.

## 0.63.0.0

### Breaking changes

* Thanks to new IME support with SDL2, `IClyde.TextInputStart()` and `IClyde.TextInputStop()` must now be appropriately called to start/stop receiving text input when focusing/unfocusing a UI control. This restriction is applied even on the (default) GLFW backend, to enforce consistent usage of these APIs.
* `[GUI]TextEventArgs` have been renamed to `[GUI]TextEnteredEventArgs`, turned into records, and made to carry a `string` rather than a single text `Rune`.
* IoC and `DependencyCollection` `Register` methods now have a `TInterface : class` constraint.
* [ABI] `IoCManager.InitThread` now returns the `IDependencyCollection`.

### New features

* Fixes for compiling & running on .NET 7. You'll still have to edit a bunch of project files to enable this though.
* `FormattedMessage.EnumerateRunes()`
* `OSWindow.Shown()` virtual function for child classes to hook into.
* `IUserInterfaceManager.DeferAction(...)` for running UI logic "not right now because that would cause an enumeration exception".
* New `TextEdit` control for multi-line editable text, complete with word-wrapping!
* `Rope` data structure for representing large editable text, used by the new `TextEdit`.
* Robust now has IME support matching SDL2's API. This only works on the SDL2 backend (which is not currently enabled by default) but the API is there:
    * `IClyde.TextInputStart()`, `IClyde.TextInputStop()`, `IClyde.TextInputSetRect()` APIs to control text input behavior.
    * `TextEditing` events for reporting in-progress IME compositions.
    * `LineEdit` and `TextEdit` have functional IME support when the game is running on SDL2. If you provide a font file with the relevant glyphs, CJK text input should now be usable.
* `Register<T>` (single type parameter) extension method for `IDependencyCollection`.

### Bugfixes

* Fixes erroneous literal "\\n" inside the Clyde debug panel.
* Fixed Lidgren connection status changes potentially getting mislogged.
* Fixed missing components not being correctly saved for maps

* Fix hot reload unit tests.

### Other

* Properly re-use `HttpClient` in `NetManager` meaning we properly pool connections to the auth server, improving performance.
* Hub advertisements have extended keep-alive pool timeout, so the connection can be kept active between advertisements.
* All HTTP requests from the engine now have appropriate `User-Agent` header.
* `bind` command has been made somewhat more clear thanks to a bit of help text and some basic completions.
* `BoundKeyEventArgs` and derivatives now have a `[DebuggerDisplay]`.
* Text cursors now have a fancy blinking animation.
* `SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH` is set on the SDL2 windowing backend, so clicking on the game window to focus it will pass clicks through into the game itself, matching GLFW's behavior.
* Windows clipboard history paste now works.
* Improved multi-window UI keyboard focusing system: a single focused control is now tracked per UI root (OS window), and is saved/restored when switching between focused window. This means that you (ideally) only ever have a UI control focused on the current OS window.

### Internal

* `uitest2` is a new command that's like `uitest` but opens an OS window instead. It can also be passed an argument to open a specific tab immediately.
* Word-wrapping logic has been split off from `RichTextEntry`, into a new helper struct `WordWrap`.
* Some internal logic in `LineEdit` has been shared with `TextEdit` by moving it to a new `TextEditShared` file.
* SDL2 backend now uses `[UnmanagedCallersOnly]` instead of `GetFunctionPointerForDelegate`-style P/Invoke marshalling.
* Entity prototype reloading logic has been moved out of `PrototypeManager` and into a new `PrototypeReloadSystem`.
* Most usages of `IoCManager.` statically have been removed in favor of dependency injection.

## 0.62.1.0

### New features

* EntityLookup has had its flags updated to reflect the merge of EntityLookupComponent and BroadphaseComponent, with the new flags reflecting each tree: Dynamic, Static, and Sundries. Dynamic and Static store physics bodies that are collidable and Sundries stores everything else (apart from grids).

### Internal

* PVS mover updates has had their performance improved slightly.
* Physics LinkedList nodes for contacts will no longer be re-made for every contact and will just be cleared when re-used.
* Sprite / Light dynamictree allocations on the client have been dropped by using static lambdas.

  * Added VV Paths, which allow you to refer to an object by a path, e.g. `/entity/1234/Transform/WorldPosition`
  * Added VV Domains, which allow you to add "handlers" for the top-most VV Path segment, e.g. `/entity` is a domain and so is `/player`...
  * Added VV Type Handlers, which allow you to add "custom paths" under specific types, even dynamically!
  * Added VV Path networking, which allows you to read/write/invoke paths remotely, both from server to client and from client to server.
  * Added `vvread`, `vvwrite` and `vvinvoke` commands, which allow you to read, write and invoke VV paths.
  * Added autocompletion to all VV commands.
  * Please note that the VV GUI still remains the same. It will be updated to use these new features in the future.

* Changed Lidgren to be compiled against `net6.0`. This unlocks `Half` read/write methods.
* Lidgren has been updated to [0.2.2](https://github.com/space-wizards/SpaceWizards.Lidgren.Network/blob/v0.2.2/RELEASE-NOTES.md). Not all the changes since 0.1.0 are new here, since this is the first version where we're properly tracking this in release notes.
* Robust.Client now uses our own [NFluidsynth](https://github.com/space-wizards/SpaceWizards.NFluidsynth) [nuget package](https://www.nuget.org/packages/SpaceWizards.NFluidsynth).

### Internal

* Renamed Lidgren's assembly to `SpaceWizards.Lidgren.Network`.
* Rogue `obj/` folders inside Lidgren no longer break the build.
* Renamed NFluidsynth's assembly to `SpaceWizards.NFluidsynth`
