+## [3.2.0] - 2026-01-12
+
+### 🎉 新特性
+
+#### 模型类名前缀支持
+- ✅ **支持配置文件配置**：在 `generator_config.yaml` 中配置 `models.class_prefix`，自动为生成的模型类添加前缀。
+- ✅ **性能优化**：为 `ConfigRepository` 添加缓存机制，减少磁盘 I/O。

+    // Since ConfigRepository.loadSync() without args looks for default file, we need a way to inject the config or point it to our file.
+    // The current implementation of SwaggerConfig calls ConfigRepository.loadSync() which defaults to finding a config file.
+
+    // Changing the implementation of StringHelper to depend on a reloadable config or global state would be better,
+    // but without changing that, we rely on how ConfigRepository finds the file.
+    // Ideally we should test ConfigRepository logic separately from StringHelper if StringHelper uses a static/global config lookup.
+
+    // BUT, wait. ConfigRepository.loadSync() does THIS:
+    // final file = File(configPath ?? PathResolver.findConfigFile() ?? '');
+
+    // If we want SwaggerConfig (static) to pick up our test config, we might need to trick PathResolver
+    // OR we can explicitly pass the config path if the code supported it, but StringHelper uses static SwaggerConfig.modelClassPrefix.
+
+    // The current implementation of `SwaggerConfig.modelClassPrefix` is:
+    // static String? get modelClassPrefix => ConfigRepository.loadSync().modelClassPrefix;
+
+    // So every time we call `StringHelper.generateClassName`, it calls `ConfigRepository.loadSync()`.
+    // `ConfigRepository.loadSync()` calls `PathResolver.findConfigFile()`.
+
+    // Since we cannot easily mock `PathResolver`'s static method or filesystem search path in a unit test without dependency injection,
+    // we might face issues testing `StringHelper` integration end-to-end here unless we run this test in a context where `findConfigFile` returns our temp file.
+
+    // However, for verify purposes, verifying `ConfigRepository` parses it is the most critical part we added.
+    // The `StringHelper` logic is simple string concatenation.
