v1.0.4

Added

• Added direct TestValidate(...) and TestValidateAsync(...) helpers for strongly typed validator tests.
• Added CrabalidatorTestHost and builder APIs for DI-backed request validation in tests.
• Added assembly discovery helpers for lightweight test hosts that validate requests without a full application host.
• Documented direct request validator tests and lightweight test host usage for handlers and automations.

v1.0.3

Added

• Added Crabalidator.Testing package for lightweight validator tests without a full application host.
• Added AddCrabalidatorTesting(...) and AddCrabalidatorTestingAdapter(...) registration helpers.
• Added direct validator test runner through CrabalidatorTest.For<TValidator>().
• Added validation result assertions for valid results, property failures, error messages, error codes, severity, and multiple property errors.

v1.0.2

Added

• Built-in rule extension methods for strings, comparable values, collections, membership checks, defaults, and null/default checks in the base Crabalidator namespace.
• BenchmarkDotNet coverage for built-in rule extensions against FluentValidation equivalents.
• BenchmarkDotNet coverage for custom Must(...) predicates using public static, public instance, and fallback lambda delegates.
• Explicit nested validator helpers through ValidateNestedWith<TValidator>(...) and ValidateEachWith<TValidator>(...).

Optimized

• Optimized DynaBee generated validators to emit direct calls for visible Must(Func<TProperty, bool>) delegate methods.
• Added fast-path support for public static Must predicates and public instance predicates with captured targets.
• Updated built-in extension rules that require predicate state to use visible predicate methods so generated validators can avoid Delegate.Invoke.
• Improved mixed extension-rule validation performance against FluentValidation baselines.

Fixed

• Preserved property types when explicit nested validator helpers receive object-typed property expressions.
• Allowed explicit nested validator selection without manually constructing validators, keeping dependency injection intact.
• Kept opaque lambdas and private predicate methods on the safe fallback path.

v1.0.1

Added

• Inferred nested object validation through ValidateNested(...).
• Inferred collection element validation through ValidateEach(...).
• Type-based nested validator overloads for explicit validator selection without manual construction.

Fixed

• Resolved inferred nested validators from dependency injection so child validators can use constructor dependencies and registered lifetimes.
• Built DI validator plans with the active service provider for compiled validators and diagnostics.
• Avoided manual new validator construction in samples, README snippets, and benchmark nested validation setup.

v1.0.0

Added

• Initial Crabalidator solution structure based on DynaBee.
• Library, test, benchmark, sample, documentation, package, and CI scaffolding.
• Stable NuGet package metadata, package icon, SourceLink, deterministic builds, symbols, and release workflow support.
• Core validation model with validators, contexts, results, descriptors, diagnostics, and fluent rule configuration.
• Public validation APIs through CrabValidator<T>, IValidator<T>, IAsyncValidator<T>, ICrabalidator, and ValidationResult.
• Fluent RuleFor(...) rules for empty checks, length checks, comparisons, equality, and custom predicates.
• Property-level When(...) and Unless(...) conditions.
• Property cascade behavior through Cascade(CascadeMode.Stop).
• Nested object validation through SetValidator(...).
• Collection element validation through RuleForEach(...).
• Async custom validation through MustAsync(...) with cancellation support.
• Async nested validator execution.
• Backend-neutral validation planning with rule order, failure metadata, diagnostics, and interpreted execution.
• DynaBee sync generation backend with generated validator types, generated method bodies, compiled invokers, and registry caching.
• DynaBee-generated hot paths for direct sync validation, typed property getters, typed rule checks, typed Must(...) delegates, conditions, nested validation, and collection validation.
• Dependency injection registration through Microsoft.Extensions.DependencyInjection.
• Validator discovery, compiled validator adapters, and the default Crabalidator runtime service.
• Runtime diagnostics for registered validators and readable validation plan output through DescribePlan(...).
• Basic console sample covering sync rules, conditions, nested validation, collection validation, async validation, and diagnostics.
• BenchmarkDotNet scenarios for direct, interpreted, generated DI, nested, async, and delegate-heavy validation paths.
• FluentValidation benchmark baselines for sync, nested, async, and delegate-heavy validation scenarios.

Optimized

• Reduced context allocations in direct, DI, nested, and generated validation hot paths.
• Inlined nested plan execution to avoid intermediate child ValidationResult allocations.
• Avoided duplicate failure collection copies when plans produce invalid results.
• Pre-sized validation failure collections from validation plan estimates.
• Optimized generated invalid paths for common rule kinds and delegate predicates.

Notes

• Crabalidator targets net8.0, net9.0, and net10.0.
• DynaBee is an internal generation backend dependency and is not exposed through Crabalidator public APIs.
• Validators that contain async rules must be executed with ValidateAsync(...).
• NativeAOT/mobile-friendly generation is not part of this release.
