FluentValidation 9 is a major release. Please read the upgrade notes at https://docs.fluentvalidation.net/en/latest/upgrading-to-9.html Changes in 9.0.0: * Removed support for netstandard1.1 and netstandard1.6 * Default email validation mode now uses the same logic as ASP.NET Core. Previous regex behaviour is opt-in. * TestHelper advanced mode now has more features (see https://docs.fluentvalidation.net/en/latest/testing.html#advanced-test-extensions) * Equal/NotEqual now perform ordinal comparison when used with string properties * Severity can now be set dynamically with a callback * Removed WithLocalizedMessage (WithMessage that takes a callback is the replacement) * Removed ResourceName from ValidationFailure * Removed ResourceName and ResourceType from IStringSource. * Removed SetCollectionValidator which was deprecated in 8.0 * Additional overload of OnAnyFailure that can receive a collection of validation failures * Remove DisplayAttribute integration and reference to DataAnnotations. * ComparisonProperty placeholder is now formatted like PropertyName * Translations of default error messages into other languages are now lazily-loaded * Added Slovenian translations of default error messages. * Added WithMessageArgument to the test helpers. * Add additional overload of SetValidator that takes a Func that receives the current property value. * ASP.NET Core: FluentValidationModelValidatorProvider and FluentValidationModelValidator are now public. * Work around a bug in ASP.NET Core's integration testing components that can cause ConfigureServices to run multiple times. * SourceLink integration. * {CollectionIndex} placeholder can now be accessed in child validators. Full release notes can be found at https://github.com/FluentValidation/FluentValidation/blob/master/Changelog.txt FluentValidation 8 is a major release. Please read the upgrade notes at https://fluentvalidation.net/upgrading-to-8 Changes in 8.6.2: * Ensure CollectionIndex works in async workflow. Changes in 8.6.1: * Added explicit netcoreapp3.1 target to the ASP.NET Core integration. Changes in 8.6.0: * Add support for ASP.NET Core 3.1 * Fixed issue with property indexers being incorrectly stripped out when using test extensions. * AddToModelState no longer includes a dot if PropertyName is null Changes in 8.5.1: * Ensure lazily loaded calls to WithMessage can be used for client-side validation, provided they don't attempt to access model properties from inside the delegate (eg when using IStringLocalizer). * Fix issue where OnFailure didn't work properly when invoked on validators with conditions. Changes in 8.5.0: * Add additional overload of the EmailAddress validator for compatibility with ASP.NET Core's default email validation. * Simplify the advanced testhelper syntax. * Add support for ASP.NET Core 3. * Add support for defining child rules inline. * ValidatorDescriptor now has consistent handling of model-level rules. * RuleForEach can now access collection index in error message with {CollectionIndex} placeholder. * Welsh language translations of default error messages. * Hungrian language translations of default error messages. * Indonesian language translations of default error messages. * Using RuleForEach combined with When is now more intuitive. * Fixed order of rule execution when using async validation. Changes in 8.4.0: * Added simplified version of several messages across all translations to aid with ASP.NET Clientside validation. * New enum validator for string properties. Changes in 8.3.0: * Fix issue in ASP.NET Core integration with GetServiceProvider not working correctly when invoked against a CustomContext/MessageBuilderContext. * Improved how LanguageStringSource works with error-code overrides. * Fix thread-safety issue with use of PropertyValidatorOptions.Empty (now removed). * Improved how calls to When/Unless are handled internally. * DelegatingValidator is now marked as deprecated. * Improvements to Croatian language translations. * Improvements to Georgian language translations. * Resolved subtle bug where top-level WhenAsync wouldn't work correctly when wrapping a top-level call to When. Changes in 8.2.3: * Fix issue in WebApi integration where DataAnnotations validators could generate duplicate messages when in the same project as FluentValidation. Changes in 8.2.2: * Fix FluentValidation.DependencyInjection package name. Changes in 8.2.1: * Resolved issue using InjectValidator with RuleForEach. * Add support for a default IValidatorInterceptor to be registered with the ASP.NET Core Service Provider. Changes in 8.2.0: * Add extensions for injecting child validators using the ASP.NET Core Service Provider. * Implement RuleFor(...).ForEach(...) as an alternative to RuleForEach. * WithLocalizedMessage is deprecated. Use the overload of WithMessage that takes a Func instead. Changes in 8.1.3: * Resolved issue where clientside validation was incorrectly generating metadata for rules with shared conditions. * ScalePrecisionValidator now has a public method in the fluent interface. * Fix placeholder names in ScalePrecisionValidator for consistency. * Updates to Portuguese (Brazil) translations. Changes in 8.1.2: * Fix issue where shared When/Unless conditions didn't execute correctly when used with RuleForEach. Changes in 8.1.1: * Added RuleSetsExecuted property on ValidationResult. * Resolved issue introduced in 8.1 where the shared condition cache does not work correctly with RuleForEach (#970). Changes in 8.1: * Add format support in message placeholders. * Added support for overriding indexers for collection rules. * Allow error codes to be used to override localization key in the Language Manager. * Additional error details are now shown in the ShouldNotHaveValidationErrorFor test extension. * Conditions defined with root-level When/WhenAsync/Unless/UnlessAsync are now only executed once (instead of once for each rule). * Support Otherwise method chained from root-level When/WhenAsync/Unless/UnlessAsync. * Minor wording changes to default English error messages. * Japanese translation of the default error messages. * Added Skip property to MVC5's CustomizeValidatorAttribute for parity with AspNetCore and WebApi. * Remove type constraint on the OverridePropertyName overload that takes an expression. Added Skip property to MVC5's CustomizeValidatorAttribute to bring parity with AspNetCore and WebApi integration. Changes in 8.0: * Support validating only specific properties by path. * Added OnFailure method * Deprecated RuleFor(..).SetCollectionValidator in favour of RuleForEach(...).SetValidator * IStringSource.GetString now takes a validation context instead of a model instance. * Introduce PropertyValidatorOptions in order to clean up the IPropretyValidator interface. * Moved the legacy ValidatorAttribute and AttributedValidatorFactory into a separate FluentValidation.Attributes package. * Remove the pre-7.0 localization mechanism * Remove the pre-7.0 methods for custom validation * Removed many other deprecated methods Full release notes can be found at https://github.com/JeremySkinner/FluentValidation/blob/master/Changelog.txt
