The control's release notes can be found on our web site, looking for the Release Notes column in the control's main page. Click here for direct link.
2:
A subscript was used that is outside of the valid range of array subscripts defined in the DIMENSION statement. This might also be caused by using two subscripts with a one-dimensional array. 

The following VFP sample generates the Invalid subscript reference (Error 31)

with thisform.TreeCube1
	with .FrontFace.CreateTree
		.Columns.Add("Progress").Alignment = 0
		with .Items
			with .Add("")
				.Height = 32
				.BackgroundExt(0) = "none[(2,2,100%-4,100%-4)](top[24,text=`10%`],bottom[6,back=RGB(204,204,204)](left[10%,back=RGB(0,120,215)]))"
				.BackgroundExtValue(0,4,2) = "25%"
				.BackgroundExtValue(0,2,4) = .BackgroundExtValue(0,4,2)
			endwith
		endwith
	endwith
endwith

You can replace calling of the BackgroundExtValue property, using the Template/TemplateDef properties of the control as in the following VFP sample:

LOCAL cObject
with thisform.TreeCube1
	with .FrontFace.CreateTree
		.Columns.Add("Progress").Alignment = 0
		with .Items
			cObject = .Add("")
			with cObject
				.Height = 32
				.BackgroundExt(0) = "none[(2,2,100%-4,100%-4)](top[24,text=`10%`],bottom[6,back=RGB(204,204,204)](left[10%,back=RGB(0,120,215)]))"
*				.BackgroundExtValue(0,4,2) = "25%"
				thisform.TreeCube1.TemplateDef = "dim cObject"
						thisform.TreeCube1.TemplateDef = cObject
						thisform.TreeCube1.Template = "cObject.BackgroundExtValue(0,4,2) = `25%`"
*				.BackgroundExtValue(0,2,4) = .BackgroundExtValue(0,4,2)
				thisform.TreeCube1.Template = "cObject.BackgroundExtValue(0,2,4) = cObject.BackgroundExtValue(0,4,2)"
			endwith
		endwith
	endwith
endwith
