Data Integration 3.2.0(stable) (What's New)
When you compare this release to the previous one, you will see that the changes are more evolutionary, rather than revolutionary. Even so, there have been a large amount of changes for a minor version increase. The main focus of the release is once again stability and usability. We went through a large number of pet-peeves, common mis-understandings and simply solved them, either through new features or by modifying existing ones. On top of that we worked on the clustering side to make that mode "cloud-ready" with dynamic clustering, making it more solid, adding features too.
