- Add QgsDataDefined class - Add QgsDataDefinedButton class - Add data defined Python support - Add standalone SVG selector dialog to QgsSvgSelectorWidget class - Fix for #4607, show only pertinent fields when setting a data defined value - Fix for #5048 and #5049, data defined settings are literally used - Fix for #5726, number formatting does not work for expressions - Fix for #7755, using bufferSize to enable/disable label buffer is confusing - Fix for #7779, labels do not register in label collision engine; and for #4719, inactive options in labeling dialog - Prepare label text's expression upfront when preparing layer; makes rendering much faster - Change name of 'feature obstacles' to appropriate terminology
