If you use Developer Express components and need to see what has changed between versions, I have built a tool that will display all the issues that they have included in their release notes between version 6.1.0 to 7.3.5 (you can add additional release notes if you want to) in a grid. This allows you to filter, sort, group, etc them so you can see exactly what has changed.

The following link provides additional information about this tool...

UPDATE: The viewer is no longer available. It is no longer relevant since DevEx updated the format for their release notes.
