-### Breaking changes
-
-* More members in `IntegrationInstance` now enforce that the instance is idle before accessing it.
-* `Prototype.ValidateDirectory` now requires that prototype IDs have no spaces or periods in them.
-* `IPrototypeManager.TryIndex` no longer logs errors unless using the overload with an optional parameter. Use `Resolve()` instead if error logging is desired.
-* `LocalizedCommands` now has a `Loc` property that refers to `LocalizationManager`. This can cause compile failures if you have static methods in child types that referenced static `Loc`.
-* `[AutoGenerateComponentState]` now works on parent members for inherited classes. This can cause compile failures in certain formerly silently broken cases with overriden properties.
-* `Vector3`, `Vector4`, `Quaternion`, and `Matrix4` have been removed from `Robust.Shared.Maths`. Use the `System.Numerics` types instead.
-
-### New features
-
-* `RobustClientPackaging.WriteClientResources()` and `RobustServerPackaging.WriteServerResources()` now have an overload taking in a set of things to ignore in the content resources directory.
-* Added `IPrototypeManager.Resolve()`, which logs an error if the resolved prototype does not exist. This is effectively the previous (but not original) default behavior of `IPrototypeManager.TryIndex`.
-* There's now a ViewVariables property editor for tuples.
-* Added `ColorNaming` helper functions for getting textual descriptions of color values.
-* Added Oklab/Oklch conversion functions for `Color`.
-* `ColorSelectorSliders` now displays textual descriptions of color values.
-* Added `TimeSpanExt.TryTimeSpan` to parse `TimeSpan`s with the `1.5h` format available in YAML.
-* Added `ITestContextLike` and related classes to allow controlling pooled integration instances better.
-* `EntProtoId` VV prop editors now don't allow setting invalid prototype IDs, inline with `ProtoId<T>`.
-* Custom VV controls can now be registered using `IViewVariableControlFactory`.
-* The entity spawn window now shows all placement modes registered with `IPlacementManager`.
-* Added `VectorHelpers.InterpolateCubic` for `System.Numerics` `Vector3` and `Vector4`.
-* Added deconstruct helpers for `System.Numerics` `Vector3` and `Vector4`.
-
-### Bugfixes
-
-* Pooled integration instances returned by `RobustIntegrationTest` are now treated as non-idle, for consistency with non-pooled startups.
-* `SharedAudioSystem.SetState` no longer calls `DirtyField` on `PlaybackPosition`, an unnetworked field.
-* Fix loading texture files from the root directory.
-* Fix integration test pooling leaking non-reusable instances.
-* Fix multiple bugs where VV displayed the wrong property editor for remote values.
-* VV displays group headings again in member list.
-* Fix a stack overflow that could occur with `ColorSelectorSliders`.
-* `MidiRenderer` now properly handles `NoteOn` events with 0 velocity (which should actually be treated as `NoteOff` events).
-
-### Other
-
-* The debug assert for `RobustRandom.Next(TimeSpan, TimeSpan)` now allows for the two arguments to be equal.
-* The configuration system will now report an error instead of warning if it fails to load the config file.
-* Members in `IntegrationInstance` that enforce the instance is idle now always allow access from the instance's thread (e.g. from a callback).
-* `IPrototypeManager` methods now have `[ForbidLiteral]` where appropriate.
-* Performance improvements to physics system.
-* `[ValidatePrototypeIdAttribute]` has been marked as obsolete.
-* `ParallelManager` no longer cuts out exception information for caught job exceptions.
-* Improved logging for PVS uninitialized/deleted entity errors.
-
-### Internal
-
-* General code & warning cleanup.
-* Fix `VisibilityTest` being unreliable.
-* `ColorSelectorSliders` has been internally refactored.
-* Added CI workflows that test all RT build configurations.
-
-## 264.0.0
-
-### Breaking changes
-
-* `IPrototypeManager.Index(Type kind, string id)` now throws `UnknownPrototypeException` instead of `KeyNotFoundException`, for consistency with `IPrototypeManager.Index<T>`.
-
-### New features
-
-* Types can now implement the new interface `IRobustCloneable<T>` to be cloned by the component state source generator.
-* Added extra Roslyn Analyzers to detect some misuse of prototypes:
-  * Network serializing prototypes (tagging them with `[Serializable, NetSerializable]`).
-  * Constructing new instances of prototypes directly.
-* Add `PrototypeManagerExt.Index` helper function that takes a nullable `ProtoId<T>`, returning null if the ID is null.
-* Added an `AlwaysActive` field to `WebViewControl` to make a browser window active even when not in the UI tree.
-* Made some common dependencies accessible through `IPlacementManager`.
-* Added a new `GENITIVE()` localization helper function, which is useful for certain languages.
-
-### Bugfixes
-
-* Sprite scale is now correctly applied to sprite boundaries in `SpriteSystem.GetLocalBounds`.
-* Fixed documentation for `IPrototypeManager.Index<T>` stating that `KeyNotFoundException` gets thrown, when in actuality `UnknownPrototypeException` gets thrown.
-
-### Other
-
-* More tiny optimizations to `DataDefinitionAnalyzer`.
-* NetSerializer has been updated. On debug, it will now report *where* a type that can't be serialized is referenced from.
-
-### Internal
-
-* Minor internal code cleanup.
-
-
-## 263.0.0
-
-### Breaking changes
-
-* Fully removed some non-`Entity<T>` container methods.
-
-### New features
-
-* `IMidiRenderer.LoadSoundfont` has been split into `LoadSoundfontResource` and `LoadSoundfontUser`, the original now being deprecated.
-* Client command execution now properly catches errors instead of letting them bubble up through the input stack.
-* Added `CompletionHelper.PrototypeIdsLimited` API to allow commands to autocomplete entity prototype IDs.
-* Added `spawn:in` Toolshed command.
-* Added `MapLoaderSystem.TryLoadGeneric` overload to load from a `Stream`.
-* Added `OutputPanel.GetMessage()` and `OutputPanel.SetMessage()` to allow replacing individual messages.
-
-### Bugfixes
-
-* Fixed debug asserts when using MIDI on Windows.
-* Fixed an error getting logged on startup on macOS related to window icons.
-* `CC-BY-NC-ND-4.0` is now a valid license for the RGA validator.
-* Fixed `TabContainer.CurrentTab` clamping against the wrong value.
-* Fix culture-based parsing in `TimespanSerializer`.
-* Fixed grid rendering blowing up on tile IDs that aren't registered.
-* Fixed debug assert when loading MIDI soundfonts on Windows.
-* Make `ColorSelectorSliders` properly update the dropdown when changing `SelectorType`.
-* Fixed `tpto` allowing teleports to oneself, thereby causing them to be deleted.
-* Fix OpenAL extensions being requested incorrectly, causing an error on macOS.
-* Fixed horizontal measuring of markup controls in rich text.
-
-### Other
-
-* Improved logging for some audio entity errors.
-* Avoided more server stutters when using `csci`.
-* Improved physics performance.
-* Made various localization functions like `GENDER()` not throw if passed a string instead of an `EntityUid`.
-* The generic clause on `EntitySystem.AddComp<T>` has been changed to `IComponent` (from `Component`) for consistency with `IEntityManager.AddComponent<T>`.
-* `DataDefinitionAnalyzer` has been optimized somewhat.
-* Improved assert logging error message when static data fields are encountered.
-
-### Internal
-
-* Warning cleanup.
-* Added more tests for `DataDefinitionAnalyzer`.
-* Consistently use `EntitySystem` proxy methods in engine.
-
-
-## 262.0.0
-
-### Breaking changes
-
-* Toolshed commands will now validate that each non-generic command argument is parseable (i.e., has a corresponding type parser). This check can be disabled by explicitly marking the argument as unparseable via `CommandArgumentAttribute.Unparseable`.
-
-### New features
-
-* `ToolshedManager.TryParse` now also supports nullable value types.
-* Add an ignoredComponents arg to IsDefault.
-
-### Bugfixes
-
-* Fix `SpriteComponent.Layer.Visible` setter not marking a sprite's bounding box as dirty.
-* The audio params in the passed SoundSpecifier for PlayStatic(SoundSpecifier, Filter, ...) will now be used as a default like other PlayStatic overrides.
-* Fix windows not saving their positions correctly when their x position is <= 0.
-* Fix transform state handling overriding PVS detachment.
