## ![](https://stechq.github.io/cdn/release/notes/plateau-studio/plateau-studio-common/plateau-studio/party-horn.svg) **New Features**

### Highlights on Plateau Studio

- We’ve introduced a **New Workflow Engine**, replacing legacy Camunda 7 and removing third-party dependencies. This release brings major architectural improvements that enhance control, reliability, and scalability.
With **unified data management**, issues related to consistency and data loss are resolved.

- **UI Settings files** are now **more flexible and app-sharable**. You can now add them to modules, folders, or the root directory of your application. Adding settings under a module enables sharing between apps and ensures consistency in modular structures by defining them once in the parent application. 

    **To continue development**, don’t forget to select and save your settings under Application Settings — Plateau Studio will guide you if any action is required during app launch.

- **Themes** are now flexible and **app-sharable**. To enable compatibility with the new structure, existing themes need to be migrated via the Theme Settings screen.

- **Task Locking Mechanism** is now available in Studio Workflow, it is to better manage user interactions on tasks. When a user opens a task, it is automatically locked to them, preventing others from making changes at the same time. The lock is automatically released when the lock duration expires, ensuring controlled and conflict-free task handling.

- **S3 Multipart & Policy Support** is now available in Plateau Studio Workflow. File uploads have been improved with automatic content type detection, which is now included in the file's metadata for more accurate and efficient handling.

You can create or edit your *S3 bucket policy* when **uploading** your file to Amazon S3 Storage. Improved S3 uploads by automatically detecting the file’s content type and including it in the uploaded metadata.

- **Logging in Studio Workflow has been enhanced to improve traceability**. Business keys are now included in log entries as [BK], allowing easier tracking of processes. Additionally, correlation IDs are now synchronized between Form Manager and Workflow Manager, appearing as [C] in logs for seamless end-to-end request tracing.

- **Using constants in scripts** has been updated in Studio Workflow. The **flow.context.constants** property is now **deprecated** and replaced with the new **flow.getConstant() method** (It will be auto-generated when you add a constant through the +ADD > Constant), offering a cleaner and more consistent way to retrieve constant values in your workflows.

## ![](https://stechq.github.io/cdn/release/notes/plateau-studio/plateau-studio-common/plateau-studio/bugs.svg) **Bug Fixes**

### Fixes on Plateau Studio


- In the **compiled export dialog**, previously the **download button** remained **disabled** even after **deselecting** an **invalid item**. Now, the system automatically revalidates selections with every change. If all selected items are **valid**, the **download button** is **enabled** and the **error message** is **cleared** immediately.
- Resolved an issue where deleted settings models were not properly removed from app settings, causing errors and warnings.



- Fixed an issue where **modified models were not saved if they were not open in the current tab.** Previously, if a model had been modified but was not open in the current tab, attempting to save it would fail and result in data loss.




### Fixes on UI

- **Scroll behavior in the UI Editor area has been improved**. Scrolling now works **smoothly** when a component is **selected** or **hovered**, while **default browser behavior** is preserved when **nothing is selected**. These improvements provide a more **consistent** and **fluid** experience across **mouse** and **touchpad**/**trackpad** inputs.

- Fixed an issue that caused the page to **automatically scroll to the top** when making style, prop, or event changes to **components located further down** on long pages. The scroll position **is now preserved** during these changes, resulting in a smoother and more efficient experience.


### Fixes on Workflow

- Fixed an issue where variables (vars, input, output) of type Datatype were displayed as unknown in the script editor within the flow. Now, the selected Datatype and its elements are properly recognized and appear in IntelliSense.
