機能

• Added support for System.Text.Json.JsonNode and JsonArray through new assertions as well as the BeEquivalentTo API.
• Added WithoutMessage to allow asserting an exception message does not contain a wildcard pattern.
• Added Value.ThatMatches and Value.ThatSatifies to build inline assertions when using BeEquivalentTo.
• Added WithStrictTyping and WithStrictTypingFor to BeEquivalentTo to ensure types also match.
• Added ExcludingMembersNamed to BeEquivalentTo to exclude fields and properties anywhere in the graph.
• Added Should().Throw(), ThrowAsync() and ThrowWithinAsync() flavors that don’t require a specific exception type.
• Clarified the date/time type when comparing non-compatible dates and times in BeEquivalentTo.
• Improved the rendering of exception messages when using WithMessage for better readability.
• Improved support for rendering multi-dimensional arrays in failure messages.
• Improved subject identification when chaining multiple assertions using Which.

不具合の修正

• Ensured WithTracing is safe when used with BeEquivalentTo globally.
• Fixed a regression from 8.1.0 where a NullReferenceException was thrown during subject identification.
• Fixed a formatting exception when {} is used as a dictionary key.
• Removed the PowerShell script that opens the website because it misbehaves.
• All Should() methods on reference types are now annotated with the [NotNull] attribute for a better Fluent Assertions experience when nullable reference types are enabled.
• Fixed a regression in which CompleteWithinAsync treated a canceled task as an exception.
