Comparing Resource Versions

You can compare resources in the workbench in several different ways:

When you select a resource in the workbench you can compare it to a version that is in the local history.  The local history is a representation of each edit and save that has been made to the resource since it was added to the workbench. 

When you select a resource in the workbench, you can compare it with a version of the resource that has been released to the repository.  This requires you to choose a version of the resource from a list.

When you select a resource in the workbench, you can compare it with the version of that resource that is currently released to the stream.  

When you select a resource in the workbench that has been modified, you can compare it with its state prior to modification. This is because the base version denotes the version you had loaded.

See Three-way compare.

The result of any compare will appear in a compare editor.
