Project: QGIS
Version: 3.6.0
This change allows users to select multiple existing categories and group them into a single category, which applies to any of the values from the selection.
This allows simpler styling of layers with a large number of categories, where it may be possible to group numerous distinct categories into a smaller, more managable set of categories which apply to multiple values.
The option is available from the right click context menu in the categories list view, whenever multiple categories are selected.
