One of the most important new features is that you can now edit the internal indicator's definitions and create your own indicators (see the appropriate cheat sheet to learn about this feature). These user defined indicators can be shared on the Talend Exchange website.  You can choose to compute column indicators in Java instead of pure SQL.

New analysis was added to evaluate functional dependency between columns.

Great enhancements were made in the nominal-nominal correlation chart which is a kind of multi-dimensional analysis.

A preference page for the presentation of the profiling editors was added.

The Structure Comparison Editor allows you to drill down in the substructure differences.

The performance of Column analyses was optimized.

And several other great features.
