Upgrading GWT code from version 1.7 to version 2.0

I have already starting converting several of my GWT apps from older version of GWT to version 2.0.  According to this link the steps are as follows.

There are 3 tasks involved when upgrading a GWT 1.7 project to a GWT 2.0 project:

• Download GWT 2.0 and update your launch configurations
• HostedMode has been replaced by DevMode, so you will need to update your Eclipse project settings accordingly.
• Tests now run in HtmlUnit by default. You will need to modify some of your tests to work with HtmlUnit.
  

So far I have not run into any issues with upgrading.  As of this post I have not seen any mention of a GWT 2.0 Incubator file, but my apps seem happy with the older version gwt-incubator-july-14-2009.jar.  I have seen several warnings however while compiling with this version such as:
