November 30, 2022 - 11:13
New Version


  • Added FlatUI and 18 new light themes: Enjoy this new flat simple design. Also, there are 18 light themes you can choose from.
  • Dark Mode: Now you can use Astah in Dark Mode. About 50 themes are pre-installed.
  • Diagram Thumbnails: Now you can see all the diagrams in thumbnails and open them from this gallery.
  • Enhanced Traceability: Now Astah’s context menu provides much more detailed reference information per model. You can see where this model is used without actively looking for it by yourself.
  • Add note to specific ER Entity Attribute: Now you can directly add notes to a specific ER Entity Attribute. This will make your note more precise and clear to improve the whole diagram communication.
  • Flexibility in resizing Process in DFD: Now you can resize the Processes in Data Flow Diagram (DeMarco notation) more flexibly. In previous versions, the processes had to be strictly in a perfect circle, but this limitation is over.
