How do I know whether I have the latest WindowBuilder version?
We follow the same general release and naming convention that is used by Eclipse.org. On the WindowBuilder download page, you will find two columns of downloads. The first column will allow you to download the most recent GA version of the product while the second columns will allow you to download the most recent development stream (or beta stream) build. The date of the latest build is always shown at the top of the column. You can check which build you are currently using by looking at the main WindowBuilder preference page. In general, new development stream build may be directly installed over older ones.
