New additions include highlighting when connecting
objects, connectability between layers, hexagonal
grids, several new shape sets (RDP, KAOS, I*,
Jackson, ChemEng), two new renderers (WMF for
non-Windows and Cairo), rounded corners on
polylines, persistence of a number of settings,
and a new arrow head. The modification status was
improved to use unod. UML objects were improved
with text wrapping and label positioning. A host
of random persistence systems were combined into
one. Fixes were made for memory leaks, a shape
compatibility bug, dialog closing problems, and
many smaller bugs.
