[FIX](CCC Legend Visible) Regression in legend's click behavior to show/hide series - wasn't working when selectable and clickable and hoverable were all false.
[FIX](CCC Clear Selection) Clearing selection with a click wasn't possible when "selectable" is false. This excluded scenarios where the selection was performed through extension code, but its clearance should still be performed by the user. To disable clearing selection with a click, the clearSelectionMode=none should be specified, or the new interactive=false.
[FIX](CCC PointChart Formatter Nulls) The value dimension's formatter would be called to format null values of "virtual" scenes, when nullInterpolationMode is 'none'; these scenes are later hidden.
[FEAT](CCC interactive) New chart option, 'interactive', allows disabling *all* interactive behaviors with a single property. The default is true for all renderers but the 'batik' renderer, used by CGG for printing charts.
