# Changelog

All notable changes to this project will be documented in this file.

This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [1.0.0] - 2026-05-26

### Added

- **request.dispatcher:** Core mediator pattern implementation with async request/response handling
- **request.result:** Optional result wrapper types (`Result<T>`) for structured responses
- **request.validation:** Automatic validation pipeline behavior with FluentValidation integration

##  [1.1.0] - 2026-05-28

### Added

- **request.validation:** Dependency injection support for validators via `IServiceCollection.AddValidation()`
- **request.validation:** `IValidatorBuilder` for fluent validator registration and assembly scanning
- **request.validation:** Support for open generic validators and automatic closing during resolution
- **request.validation:** `Validate<T>` extension method for simplified validator invocation

### Changed

- **request.dispatcher:** Reset type caches when reloading assemblies
- **request.validation:** Reset type caches when reloading assemblies

## [2.0.0] - 2026-05-30

## Breaking changes

To have a consistent experience across all packages, some public interfaces have been renamed.

### Changed

- **request.dispatcher:** Hide pipeline internals in stack frames
- **request.validation:** Rename `IValidatorBuilder` to `IRequestValidatorBuilder` incl. extensions methods

## [Unreleased]

### Added

- **request.validation:** Support `PropertyPath` JSON converter for string values and dictionary property names

### Changed

- **request.result:** Document that `Result`/`Result<T>` equality treats any two failures as equal, ignoring error content; branch on the `Error` directly for failure-specific logic (see PLAN.md Inconsistencies#E)

### Fixed

- **request.result:** Correct the namespace in the `Prelude` doc comment (`Geekeey.Extensions.Result` → `Geekeey.Request.Result`)
- **request.result:** Fold `IsSuccess` into `Result<T>.GetHashCode` to avoid collisions between a failure and a success value whose hash is `0`
- **request.validation:** Guard null comparison bounds in `GreaterThan`/`LessThan`/`Between` etc. so a `null` bound no longer throws (`NullReferenceException`)
- **request.validation:** Return no problems when validating a `null` instance of a reference type instead of dereferencing it (`NullReferenceException`)
