• `[Conditional("JETBRAINS_ANNOTATIONS")]` attribute was removed from all annotation types, so the assembly reference to `JetBrains.Annotation.dll` is no longer automatically removed by the C# compiler. You can no longer safely use `PrivateAssets="All"` for package reference to `JetBrains.Annotations`. Consider migration to `JetBrains.Annotations.Sources` package if the dependency removal is important for you.
• New `JetBrains.Annotations.Sources` package introduced as an alternative way to embed JetBrains.Annotations into your projects without package dependency.
• Added `DefaultEqualityUsageAttribute` for equality members usage analysis.
• `MustDisposeResourceAttribute` is now allowed on struct types.
• Added the ability to specify the description for UsedImplicitlyAttribute (new 'Reason' property).
• Added `CqrsCommandAttribute`, `CqrsQueryAttribute`, `CqrsCommandHandlerAttribute`, `CqrsQueryHandlerAttribute` and `CqrsExcludeFromAnalysisAttribute` to support CQRS analyzes of naming and adherence to the pattern.
• Package icon update.
