Release Notes: Gtkwave is no longer bundled. Scheme script source files have been cleaned to remove functions provided by guile. balsa-netlist has had a number of switches removed. balsa-mgr has been reworked to use GTK+ 2.0 rather than GTK+ 1.2. balsa-c no longer requires the KCT/Cocktail tools in order to be built. New handshake protocols can now be defined in 'style' packages separate from Balsa without modifying code in share/scheme.
