If you’re a lucky owner of IntelliJ IDEA 9 Ultimate Edition, you’ll be surprised to find a new action in VCS History panel: view all changes made in commit in a single dialog. This feature makes it simpler to understand what a commit author made in his change.

To start using this feature, invoke Show History action for any file, then select revision you’d like to investigate, and then click UML icon (or press Control+Shift+D).

This opens the following diff dialog:

As you can see, 3 changes are made in layout.properties, Rounded interface and RoundedButton class. By default, green color marks what was added, blue is for changed, and gray, guess what — deleted. Well, what else can we see here? RoundedButton class doesn’t extend JComponent and does not implement ButtonModel interface anymore, but instead it extends AbstractButton class and implements MouseListener and KeyListener interfaces. Also, author has changed method paint and removed method isPressed. Interface Rounded was added from scratch and some properties were modified, added and removed in layout.properties file. Double click on a node shows standard diff dialog.

You will be able to enjoy this UML-like Diff Tool in next EAPs and also in the nearest IntelliJ IDEA 9 update.

In the upcoming Maia EAP you will find a slightly different Commit Changes dialog.

• Automatic use of JobView filter on search results.
• Support for Perforce native search query syntax (in an example below we’re looking for Job in any field)

In Maia, you will be able to use the Ctrl+D shortcut in the update info tab to see which local files were changed after you perform update from repository.

When you have changes in several files or classes and want to see what they affect, you typically use the Changes tab and then Show Diff action for every affected file or class. In Maia, you will be able to see the complete picture at once, via UML Class Diagram. It is improved to allow viewing and highlighting of changed and removed classes, methods, fields and so on when you press Ctrl+Alt+Shift+D.
