 # CHANGELOG
 
+## v1.1.0 — Validation Pipeline Hardening & Web API Focus
+
+### Changed
+- Refactored `Dispatcher` to use **strongly-typed task handling**
+  - Removed all `dynamic` usage
+  - Ensured `Task<TResult>` is awaited and returned safely
+- Dispatcher now correctly enforces **validation-before-handler execution**
+- Validation pipeline fully aggregates errors from **multiple validators**
+- Removed console sample from core focus to align library with **Web API–first usage**
+- Standardized CQRS registration via **feature assembly scanning**
+- Improved DI scoping correctness for validators and handlers
+- Clarified reusable-library boundaries (MinimalCQRS remains application-agnostic)
+
+### Added
+- Comprehensive **unit test project** for MinimalCQRS
+  - Dispatcher behavior tests
+  - Validation aggregation tests
+  - Handler invocation guards
+- **Test doubles** for commands, queries, handlers, and validators
+- Web API **integration tests** covering:
+  - Missing request body (400)
+  - Validation errors (400)
+  - Successful command execution (200)
+- Feature assembly **marker pattern** to avoid brittle `Program.Assembly` scanning
+- Improved exception handling coverage for validation failures
+
+### Removed
+- Console sample project from main solution focus (kept library Web API–oriented)
+
+### Fixed
+- Validation exceptions not being surfaced consistently
+- Incorrect assumptions about validator discovery across assemblies
+- Dispatcher behavior when handlers or validators are missing
+- Test expectations not matching actual handler contracts
+
+---
+
 ## v1.0.0 — Initial Release
