The intersection modifier works on entities contained in groups. The Symbol selection dialogs have been modified to show twice as many symbols at one time. Rotate Copy command now allows you to select two points and use the bearing angle between them for the rotation angle. They are no longer considered as having their own properties as they do not show. Numeric fields in dialogs now support the full expression analyzer - fractions work, macro variables, etc.
Wide lines convert with length and fill pattern.
Undefined layers no longer create invalid layer definitions. A bug in incorrectly assigning a filled style when the fill is transparent but not enabled has been fixed. A memory management bug that caused some large ECW drawings to crash on load has been fixed. It is no longer possible to select a new current layer and have it remain hidden or frozen. Implemented a paper-space option for line width, so the specified width prints out lines of actual width reguardless of view zoom factor.
