+## [1.1.0] - 2025-10-27
+
+### Features
+
+#### Task Naming Support
+
+- **Added task naming for `.run` effects**: Leverages Swift 6.2's SE-0469 task naming capability
+  - New optional `name` parameter in `.run(name:operation:)` for improved debugging and profiling
+  - Task names appear in Xcode debugger, Instruments, and swift-inspect
+  - Fully backward compatible—existing code works unchanged
+  - Names are preserved through all configuration methods (`.catch`, `.cancellable`, `.priority`)
+
+  ```swift
+  // Named task for better debugging
+  return .run(name: "🔄 Fetch user profile") { state in
+      let profile = try await api.fetchProfile()
+      state.profile = profile
+  }
+
+  // Dynamic naming with context
+  return .run(name: "Load user \(userId)") { state in
+      let user = try await api.fetchUser(userId)
+      state.user = user
+  }
+  ```
+
+**Benefits:**
+- Tasks are easily identifiable in development tools
+- Better observability during debugging and profiling
+- Human-readable task names in thread lists and performance traces
+
+**Requirements:**
+- Swift 6.2+ (for Task naming API support)
+
+### Documentation
+
+- **Improved README.md**: Enhanced "Result-Returning Actions" section with clearer explanations
+  - Explicitly mentions that `ActionResult` type can be freely defined per Feature
+  - Provides better context for code examples
+  - Clarifies how ChildFeature, ParentView, and callbacks work together
+  - Emphasizes dependency tracking within the view tree
+
+### Tests
+
+- Added 6 comprehensive tests for task naming feature:
+  - Basic task naming functionality
+  - Backward compatibility verification (name = nil)
+  - Name preservation through `.catch`, `.cancellable`, `.priority`
+  - Name preservation through complete configuration chaining
+- All 299 tests pass (293 existing + 6 new)
+
+### Internal
+
+- Fixed SwiftLint `function_parameter_count` violation in `Store.executeRunTask`
+
