Release Notes

Introducing UML Timing Diagrams in Astah

We’re thrilled to unveil a significant update to Astah: the addition of UML Timing Diagrams.
Timing Diagrams are essential for anyone involved in the development and analysis of real-time systems, embedded systems, or any application where understanding the timing of interactions is critical. We believe this new feature will significantly enhance your modeling capabilities and look forward to seeing the innovative ways you’ll use Timing Diagrams in your projects!

Visible Definitions Directly on Diagrams

Elevate Your Diagramming Experience

Until now, any definitions added to models were only viewable in the property view, requiring users to navigate away from the diagram to access this information. We’re excited to introduce a transformative feature: the ability to display and edit definitions directly on your diagrams. In addition to that, you can edit these definitions directly on the diagram itself.

Enhancement on State Regions

Streamline Your State Machine Diagrams

Gone are the days of cumbersome adjustments and static diagramming. We’re introducing significant enhancements to state regions in state machine diagrams, designed to supercharge your modeling efficiency and clarity.

What’s New:

• Naming State Regions: You can now assign names to each region within a state. This feature makes it faster and easier to identify specific regions.
• Flexible Reordering of Regions: You can change the display order of state regions. This flexibility eliminates the previous hassle of manually switching the contents of regions through cumbersome copy-and-paste actions. Now, ensuring your diagrams’ representation remains clear and accurate is straightforward and hassle-free.
