The gre.get_string_size API now allows you to get the bounds of wrapped text using the same breaking and wrapping algorithms that the render extension uses. Use this new API instead of hand-crafting your own text breaking algorithm in Lua!
Performance improvements align the costs for set_data, set_value, set_control_attrs
The GRE DOM interface (libgre-plugin-luagredom plugin) has been enhanced with additional API exposing common operations (set/get position, bounds, visibility).
