> When using the slim activity card design, the primary property of an activity is now displayed directly on the activity card for activities included in packages such as **Excel**, **Word**, or **Presentations**. You can now view inline details such as "Excel file used, the range appended" without opening the **Properties** panel. This makes workflows clearer and easier to read.

### Build number: 2026.0.180

### What's New

#### Enhanced compact design experience

When using the slim activity card design, the primary property of an activity is now displayed directly on the activity card for activities included in packages such as **Excel**, **Word**, or **Presentations**. You can now view inline details such as "Excel file used, the range appended" without opening the **Properties** panel. This makes workflows clearer and easier to read.

### Improvements

#### Panel improvements

You can now open and close side panels (such as **Explorer**, **Activities**, or **Properties**) by selecting their respective icons, giving you more control over your workspace, especially when working with large workflows or on smaller screens. You can collapse panels to focus on the canvas and then reopen them as needed, without removing the sidebar completely. When moving a panel with a horizontal layout, the panel is updated in the vertical layout.

Additionally, the **Profiling** tab can now be accessed from a separate side panel instead of the **Debug** ribbon tab.

### Bug Fixes

* Unexpected compilation errors occurred in some projects that contained a large number of test cases.
* A *System.NullReferenceException: Object reference not set to an instance of an object* error occurred when switching Git branches in some projects that had uncommitted changes.
* A *BC30451: 'LocalResource' is not declared. It may be inaccessible due to its protection level* error occurred in some flowchart workflows when manually entering a VB expression inside the Collection Builder in a **Send Email** activity.
* Activities restricted by the **Activities to hide** Automation Ops governance setting could still be used in certain projects.
* The **ST-NMG-004 - Display Name Duplication** Workflow Analyzer rule was unexpectedly triggered in some projects after updating the **System** activity package from v23.4.3 to v24.10.7.

### Build number: 2026.0.179

### What's New

#### New Build Project option

The new **Build Project** Workflow Analyzer option allows you to check for compilation errors without running or publishing the project. This option is useful when a workflow file was deleted or renamed, allowing the Studio compiler to flag every **Invoke Workflow File** activity that references a missing file.

#### Automatic argument renaming

When renaming arguments in a workflow, Studio now updates all **Invoke Workflow File** activity references automatically. Existing default values are preserved, ensuring you do not lose configurations already defined in those invocations.

### Improvements

Namespace errors are now marked in the **Explorer** panel and can be fixed by right-clicking the affected dependency and selecting **Repair Dependency**.

### Bug Fixes

* Activities added to a workflow were misplaced after using the scrollbar in some large projects.
* Searching for activities or keywords in the **Activities** panel returned activities from the Excel package even when not applicable when the **Group by category** option was selected in some projects.
