IntelliJ® IDEA 7.0

• New UI for merging Subversion branches
• New Password Safe tool for encrypted storing of passwords for VCS, proxy server etc.
• Bugfixes

• Stacktrace folding for Groovy code

• Support for vertical indent guides in editor (Settings | Editor | Appearance | Show vertical indent guides)
• "Show in Explorer"/"Reveal in Finder" actions in context menu
• Improved detection of project indexes rebuild necessity on IDE startup
• Code sample preview for several programming languages (currently implemented for Java, JavaScript, PHP).
• Possibility to attach source to decompiled class file directly from edit window
• Support for autoboxing when evaluating expressions in Java debugger

New background-enabled file indexing allows you to start using essential editing features almost immediately. All the advanced features become available in minutes.

The responsiveness of the user interface has been improved, with many time-consuming operations now performed in the background.

We have also introduced on-the-fly module reloading, which means that changes in .iml files (in particular, after updating from version control) no longer require reopening the entire project.

• Global unused symbols highlighting shows dead code instantly, as you type
• To overcome the verbosity of certain Java language constructs, IntelliJ IDEA can now automatically fold generic parameters, one-method anonymous classes (a.k.a. poor man's closures) and i18n-ized messages.
• 
• Colors can add a whole new dimension to the information you get through the user interface. IntelliJ IDEA 9 allows you to assign custom colors to arbitrary sets of files (Scopes) in Editor tabs or Navigation lists (Go to class/file, etc). This helps you understand at a glance which class you are looking at: a JDK class, a library, a test, a DAO, Domain logic or the UI code of your own application, and so on.
• 
• The global data flow analysis features, first introduced in IntelliJ IDEA 8.0, have been greatly improved. Now you can see all the distinct values that can reach the selected method parameter or field. The new "Dataflow from here" feature allows you to explore where a certain value or expression is passed through the method call chains.
• 
• For Swing developers, we've got a handy new feature: a small icon preview is now shown in the editor gutter any time you use an Icon in your code.
• 

• Easy class exclusion from completion & auto-import gets you rid of unwanted java.awt.List et al
• The code completion feature has received a lot of nifty improvements. In particular, you can press the completion shortcut twice to get additional options (such as inaccessible methods and fields, values of expected type accessible through an indirection, etc.)
• 
• A built-in spell checker now verifies comments, literals and identifiers in your code
• 
• Several new inspections have been added - for instance, an inspection ensuring that the conditions of assert statements have no side effects.
• 

• Run and Debug Configurations can now be quickly invoked via keyboard. Now, if you prefer not to use the mouse, you can hide the main toolbar without losing access to any important features.
• 
• Drag and drop, copy and paste files between IntelliJ IDEA and your OS native shell
• Easily jump between open files and tool window with Ctrl+Tab
• 
• Reworked bookmarks — now you can assign mnemonics to arbitrary code lines and even files in Project View
• 

IDEA 9 brings a more powerful and flexible way to set up packaging configurations (artifacts) for your project. Artifacts can be configured in the Project Structure dialog.

Packaging configurations of existing JavaEE facets are migrated to artifacts automatically.

Finally, since this version you can choose different dependency scopes - you can specify whether a dependency is "compile time", "test only", "runtime only" or "provided." The semantics of these scopes is quite similar to that of Maven scopes.

As always, IntelliJ IDEA stays on top of the evolution of the Java language. This release provides support for the JSR 308 type annotations feature.

• Simplified project configuration: it's no longer necessary to create Groovy and Grails facets
• Gradle support
• DSL for IDE support of dynamic features of Groovy frameworks
• 
• Many new intentions and inspections
• 

• Improved Scala plugin (separate download)
• Initial support for Clojure (separate download)
• 

• Background project import

• Subversion 1.6 merge tracking
• Git 'push active branches', push selected changes only
• Changelist conflict tracking
