FluentValidation 8 is a major release. Please read the upgrade notes at https://fluentvalidation.net/upgrading-to-8 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.
