+## [0.22.2] - 2025-12-02 - Session Configuration
+
+### Added
+
+- **SessionConfigSchema (0.22.2)**
+  - New configuration schema for session settings in `src/shared/constants/config.ts`
+  - `persistIndefinitely: boolean` (default: true) - toggle indefinite session persistence
+  - `maxHistoryMessages: number` (default: 100) - maximum number of messages to keep in session history
+  - `saveInputHistory: boolean` (default: true) - toggle saving user input to history
+  - Integrated into main ConfigSchema with `.default({})`
+  - Exported `SessionConfig` type from config module
+
+- **Session.truncateHistory() Method**
+  - New method in `src/domain/entities/Session.ts`
+  - Truncates message history to specified maximum length
+  - Keeps most recent messages when truncating
+
+### Changed
+
+- **HandleMessage Use Case**
+  - Added `maxHistoryMessages?: number` option to `HandleMessageOptions`
+  - Added `saveInputHistory?: boolean` option to `HandleMessageOptions`
+  - Added `truncateHistoryIfNeeded()` private method for automatic history truncation
+  - Calls `truncateHistoryIfNeeded()` after every message addition (6 locations)
+  - Checks `saveInputHistory` before saving input to history
+  - Ensures history stays within configured limits automatically
+
+- **useSession Hook**
+  - Added `config?: Config` to `UseSessionDependencies`
+  - Passes `maxHistoryMessages` and `saveInputHistory` from config to HandleMessage options
+  - Session configuration now flows from config through to message handling
+
+- **App Component**
+  - Added `config?: Config` to `AppDependencies`
