Added new mechanisms so that the shape of 3D arrow cones should not be affected by the value of BoxRatios. : added the new options HeadProportion3D and HeadScalingTransform3D, and deleted obsolete references to HeadWidth3D. : restored the functionality of TextToGraphics, TextToGraphics3D and text on a surface to Mathematica version 8. : fixed some bugs involving Oriented, ColorFunction, ReverseOrientation, ArrowShaftLength, Arrowheads. : added support for ColorFunction in Oriented. : added support for Tube objects as an alternative to Line in 3D. : removed obsolete references to pre-Mathematica 6 CurvesGraphics code, and added a new example. : With Mathematica version 7 or later you can now use the Oriented option with BSplineCurve too. : With Mathematica version 7 you can now use the Oriented option with ListCurvePathPlot and ListLinePlot too. : With Mathematica version 7 the package now uses the Cone primitive to draw 3D arrows, and it can map StreamPlots onto a surface.
