+      ## [1.1.2]
+      fix: Update plugin version display
+      Corrected the plugin version display in the IDE.
+
+      ## [1.1.1]
+      fix: Correctly generate primary keys
+      The generator was failing to identify primary key columns, resulting in generated beans without them. This has been fixed by updating the code to use the `getColumnsRef()` method, which correctly retrieves the column names for the primary key.
+
+      ## Release Notes
+
+      ### New Features and Enhancements
+
+      *   **DTO Generation:** Introduced new functionality to generate Data Transfer Object (DTO) classes alongside ActionBeans. This includes new FreeMarker templates (`actionDTO.ftl`, `actionDTO.extend.ftl`) and updated logic in `GeneratorServices.java`.
+      *   **ActionField and DTOField Enhancements:** Implemented enhancements related to the generation of `ActionField` and `DTOField` within the generated classes.
+
+      ### Refactoring and Improvements
+
+      *   **Project Structure Refactoring:** The project structure has been reorganized. Generator-related classes were moved to a new package (`com.sdk.generators.actionmodels`), and template directory names were standardized to `src/main/resources/templates`.
+      *   **Build System Updates:** Updated `build.gradle.kts`, `plugin.xml`, and Gradle wrapper files to reflect the structural and functional enhancements.
