+# Changelog
+
+All notable changes to EasyAppDev.Blazor.Store will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.0.0] - 2025-01-14
+
+### 🎉 First Stable Release
+
+This is the first stable release of EasyAppDev.Blazor.Store, featuring a complete architectural refactoring based on SOLID principles.
+
+### 🚨 Breaking Changes
+
+#### 1. StoreComponent Now Requires Utility Services
+
+**Impact**: Components inheriting from `StoreComponent<T>` will fail at runtime if utility services are not registered.
+
+**Before** (alpha versions):
+```csharp
+// Just register the store
+builder.Services.AddStore(new CounterState(0));
+```
+
+**After** (v1.0.0):
+```csharp
+// Option 1: Convenience method (recommended)
+builder.Services.AddStoreWithUtilities(
+    new CounterState(0),
+    (store, sp) => store.WithDefaults(sp, "Counter"));
+
+// Option 2: Manual registration
+builder.Services.AddStoreUtilities();
+builder.Services.AddAsyncActionExecutor<CounterState>();
+builder.Services.AddStore(
+    new CounterState(0),
+    (store, sp) => store.WithDefaults(sp, "Counter"));
+```
+
+**Why**: `StoreComponent` now uses dependency injection for debounce, throttle, caching, and async execution functionality, improving testability and following SOLID principles.
+
+#### 2. Direct Store Constructor Changed
+
+**Impact**: Direct instantiation of `Store<T>` now requires `ISubscriptionManager` parameter.
+
+**Before** (alpha versions):
+```csharp
+var store = new Store<CounterState>(new CounterState(0));
+```
+
+**After** (v1.0.0):
+```csharp
+// Use StoreBuilder pattern
+var store = StoreBuilder<CounterState>
+    .Create(new CounterState(0))
+    .Build();
+```
+
+**Why**: Separation of concerns - subscription management is now a separate responsibility handled by `ISubscriptionManager`.
+
+### ✨ New Features
+
+#### SOLID Architecture Refactoring
+
+- **Single Responsibility Principle (SRP)**
+  - Extracted `ISubscriptionManager` from `Store<T>` (subscription lifecycle management)
+  - Extracted `IAsyncActionExecutor<T>` from `StoreComponent<T>` (async action handling)
+  - Separated utility concerns: `IDebounceManager`, `IThrottleManager`, `ILazyCache`
+
+- **Interface Segregation Principle (ISP)**
+  - Split `IStore<T>` into focused interfaces:
+    - `IStateReader<T>` - Read-only state access
+    - `IStateWriter<T>` - State mutation operations
+    - `IStateObservable<T>` - Subscription/notification functionality
+  - Components can depend only on what they need
+
+- **Dependency Inversion Principle (DIP)**
+  - All components depend on abstractions, not implementations
+  - Improved testability with mockable interfaces
+  - Dependency injection throughout the library
+
+#### Dependency Injection Support
+
+- **Service Registration Extensions**
+  - `AddStoreUtilities()` - Registers debounce, throttle, and cache services
+  - `AddAsyncActionExecutor<TState>()` - Registers async action executor for a state type
+  - `AddStoreWithUtilities<TState>()` - Convenience method combining all registrations
+  - `AddScopedStoreWithUtilities<TState>()` - Scoped store with utilities (Blazor Server)
+
+- **Automatic Dependency Resolution**
+  - `StoreComponent<T>` automatically injects required services
+  - Scoped lifetime for utility services (per Blazor connection)
+  - Proper disposal and cleanup
+
+#### Structured Logging
+
+- **Replaced Console.WriteLine with ILogger<T>**
+  - Production-ready logging throughout the library
+  - Configurable log levels
+  - Integration with ASP.NET Core logging infrastructure
+  - Better debugging and monitoring capabilities
+
+#### Comprehensive XML Documentation
+
+- **1,655+ lines of XML documentation** added across 8 core interfaces:
+  - `IStateReader<T>` - 72 lines
+  - `IStateWriter<T>` - 198 lines
+  - `IStateObservable<T>` - 216 lines
+  - `ISubscriptionManager<T>` - 239 lines
+  - `IDebounceManager` - 156 lines
+  - `IThrottleManager` - 196 lines
+  - `ILazyCache` - 301 lines
+  - `IAsyncActionExecutor<T>` - 277 lines
+
+- **Enhanced IntelliSense Support**
+  - Detailed parameter descriptions
+  - Usage examples in XML `<example>` tags
+  - Remarks for best practices
+  - Exception documentation
+
+#### Middleware Improvements
+
+- **MiddlewarePipelineOptions**
+  - Configurable error handling strategies
+  - Retry logic with exponential backoff
+  - Circuit breaker pattern support
+  - Better control over middleware behavior
+
