Changes in 7.3: * Major changes to AspNetCore integration including better support for collections and implicit validation (opt-in) * Marked ValidationException as serializable when running on full framework * Fix - Updated EnumValidator's Flags support to handle the ~0 value * Fix - TestHelper checking for child validator would respond with the wrong type * Fix - Updated translations for some validators * Deprected the ValidatorAttribute. It is recommended to use the Service Provider infrastructure (AspNetCore) or an IoC container instead. Changes in 7.2: * Updated AspNetCore integration to support IValidatableObject * Updated AspNetCore integration to allow mixing multiple validation strategies in the same model * Updated AspNetCore integration to support RulesetForClientsideMessagesAttribute * Fix - Property names were not generated properly for nested types when using AddFailure inside a Custom validator * Fix - NullReferenceException when using CustomAsync but the validator is invoked synchronously * Fix - Clientside integration in AspNetCore being resolved from the root-level service provider * Fix - Allow empty string to be passed to OverridePropertyName Changes in 7.1.1: * Fix - Incorrect property name was generated when using RuleForEach combined with SetValidator * Fix - Nesting async validators inside DependentRules didn't wait for completion Changes in 7.1: * New RuleFor().Custom() method as a replacement for the old, deprecated Custom method * Improved messages in the ShouldHaveChildValidator test extension * Test helper works with nested properties * Additional overload of WithState allows access to collection item when used with RuleForEach * Fix - Wrong values were generated as part of the MVC5 clientside integration for MinLength and MaxLength validators * Fix - AssemblyScanner now excludes abstract and generic types * Fix - InvalidCastException when using lazy WithMessage combined with RuleForEach * WithState enhanced to allow access to the ValidationContext Changes in 7.0: 7.0 is a major release that contains several breaking changes, especially with Localization. If you use FluentValidation's support for localization please read the updated documentation: https://github.com/JeremySkinner/FluentValidation/wiki/f.-Localization * Localization rewrite to not require satellite assemblies * New 'Custom' rule method replaces the root-level Custom method * Switch to Netstandard based build process * Assemblies are now signed / strongly named - see https://github.com/JeremySkinner/FluentValidation/wiki/l.-Strong-naming-and-signed-packages * Fix - Possible NullReferenceException in the AspNetCore clientside integration for length validators * Fix - Don't clear the ModelValidatorProviders collection by default in the AspNetCore integration (added new ClearValidatorProviders property to control this behaviour) * Fix - Ensure IValidatorFactory is resolved from request scope in asp.net core integration * Fix - Property getter that throws an exception causes validation to fail in WebApi integration * Fix - Issue in AspNetCore integration where we tried to resolve a collection validator in some situations where a class validator should be used * Fix - Incorrect clientside validation attributes generated for email validator and credit card validator in the asp.net core integration * Fix - Child model validation now works in webapi integration * Improve splitting of PascalCased property names to support uppercase character sequences * ValidationResult.ErrorCode property now always returns the type of the PropertyValidator that generated the message, unless it's been explicitly overriden Full release notes can be found at https://github.com/JeremySkinner/FluentValidation/blob/master/Changelog.txt
