Project: QGIS

Version: 2.2.0

Feature: Thematic maps based on expressions

Categorized and Graduated thematic maps can now be created using the result of an expression. In the properties dialog for vector layers the attribute chooser has been augmented with an expression builder. So now you no longer need to write the classification attribute to a new column in your attribute table if you want the classification attribute to be a composite of multiple fields, or a formula of some sort.
