This is an old page (from 2010) describing version 8 of the ADT plugin for Eclipse. 
If you are looking for the R8 tool (a replacement for the Proguard shrinking and minification tool), go to

The following features were new in R8 (ADT 8.0.0):

- New version number scheme following the SDK Tools revision number.
- Support for true debug build. No need to change the value of debuggable in
  the Android Manifest.
  Incremental build will automatically insert debuggable==true while using
  the "export signed/unsigned application package" will not.
  If debuggable=true is set, then release builds will actually do a debug build.
- Automatic Proguard support in release builds. Only need to have a proguard.config
  property in that points to a proguard config file.
- Completely rewritten Visual Layout Editor. This is very much a work in progress.
    - full drag and drop from palette to layout for all Layout classes.
    - Move widgets inside a Layout view, from one Layout view to another and from one layout file to another.
    - Contextual menu with enum/flag type properties.
    - New zoom controls.
- New HierarchyViewer plug-in integrated in Eclipse.
- Android launch configurations don't recompile the whole workspace on launch anymore.
- android.jar source and javadoc location can now be configured.
