Changes in 7.6: * WhenAsync now works correctly when calling the non-async Validate method. * ASP.NET Core integration has been updated to ASP.NET Core 2.1. * Include statement now works when explicitly selecting properties to validate. * Added Ukranian language support. * Added Arabic language support. * Added caching when instantiating validators to obtain clientside metadata. Changes in 7.5.2: * RuleSet method can now take multiple ruleset names by usinga comma-separated string. * Make setters on ValidationFailure's properties public to allow for easier deserialization. * Additional overload for OverridePropertyName that takes an expression. * Add overload of Include that takes a func to lazily create the inner validator. * Make error code resolution pluggable using ValidatorOptions.ErrorCodeResolver Changes in 7.5.1: * Resolved issues with referencing FluentValidation from legacy PCLs. * Added support for CustomizeValidatorAttribute to the legacy WebApi integration for consistency with MVC5 and AspNetCore. Changes in 7.5: * Better handling of clientside messages when using custom overriden language resources * Added flag in the ValidationContext's RootDataContext when a validator is invoked by the automatic MVC/WebApi integration * Improvements to some of the validation tester's messages * Added Transform method to transform property values prior to validation * Improve support for DisplayAttribute / DisplayNameAttribute when inferring property display name * New language translations (Slovak/Hebrew/Brazilian Portuguese) * Cache display names by default * Ensure ShouldHaveChildValidator test method works with model-level rules * Removed netstandard1.0 support. Supported platforms are now netstandard1.1, netstandard2.0 and net45. Changes in 7.4: * Improved syntax for DependentRules * ValidationException serialization support when running on full framework * Added ComparisonProperty placeholder to some validators * The Test Helper now correctly handles read-only properties * Add CancellationToken support to ValidateAndThrowAsync and various ValidateAsync overloads * Improved functionality for custom MessageBuilders * Updated AspNetCore integration to MVC version 2.0.2 * Update MVC5 AddToModelState extension not to overwrite existing attempted values * Added SetRulesetForClientsideMessages method for MVC5/AspNetCore as an alternative to using the RulesetForClientSideMessagesAttribute Changes in 7.3: * Major changes to AspNetCore integration including better support for collections and implicit validation (opt-in) * 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 * Fix - Overload of WithName that takes a lambda generated an exception * Added versions of WhenAsync and UnlessAsync that support CancellationTokens * Simplify calls to DependentRules * Add Skip property to CustomizeValidatorAttribute in the ASP.NET Core integration 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
