+
+  This is a major update.
+
+  Deprecated: server-side image maps (use client-side instead); definition
+  of categories within proc areadef (use proc categories instead); proc print.
+
+  Discontinued attributes: proc processdata's stack; proc usedata's element,
+  proc getdata's rotate, and proc defineunits (use the $changeunits()
+  function instead).
+
+  proc rangebar has been renamed proc boxplot and there are major
+  functionality changes. Any script that uses proc rangebar will need
+  maintenance.
+
+  See http://ploticus.sourceforge.net/doc/news.html for more information.
