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 8.0: * 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
