View & Edit
-  Association lines and arrows overlap on the model name if the model is shown in Icon notation.
-  Astah would not let you enter * at the end of attribute/operation types on the diagram.
-  InstanceSpecifications and Lifelines will lose its type if you modify the name of those models without showing the type on the diagram.
-  When you export or print diagrams, some of the models will look in wrong sizes.
-  Changing font size resizes the model incorrectly if the [Auto Resize] mode is off.
-  Copying to EMF does not work for some model elements.
Reference Model Management
-  On the [Reference Model Management feature], adding and updating reference project fails if the project contains any Traceability Maps.
-  When reading diagrams from another project by using [Reference Model Management feature], customized icons do not appear correctly on the diagram.
‘Lock the Center’ mode
New option is added on each diagram’s toolbar.
By turning this new mode on, Astah will always keep the connecting points stay as they are and keep your diagrams neat and clean for you as you edit.
Suggest Feature no longer gets in your way
Suggest features – the small icons that appear when you hover on a model – this should help you create diagrams faster.
Display all on hover
Now you can see all the text by hovering on the cut-out text in the property view (the left-bottom pane of Astah).
So make your diagram editor as wide as you’d like and see the detailed info just by hovering instead of sliding the column in the property view each time.
New convenient options are added on the tree view.
When you traverse the hierarchy of the tree of your project, you can now choose from [Expand All], [Expand One Level] and [Collapse All] instead of double-clicking one by one to open/close the nodes.
State Transition Tables
State Transition Table Plug-in is also updated!
Now you can filter which states you want to show in the State Transition Table and also sort the list of states in the table as you like directly in Astah.
State Transition Table Plug-in is completely free to use. Give it a try if you are using Statemachine diagrams.
