* Gtk+ is now featuring runtime loading of dynamic modules via the
  --gtk-modules= command line switch. such modules have to export a
  G_MODULE_EXPORT void gtk_module_init (gint *argc, gchar ***argv);
  function which will be invoked to initialize the module. since such
  modules may create new widget types, they are always resident.
* The tutorial has been updated again.
* Changes to menus including tearoff menus and accelerators.
* Better support for modal dialogs.
* Removed CAN_FOCUS by default from scrollbars and button children of toolbar.
* More improvements and fixes for GtkCList and GtkCTree (i.e. row sorting).
* GtkCTree rows can be unselectable now.
* The GtkCTree API has undergone major renames (see ChangeLog entry from Lars
  Hamann on Tue Aug 18 00:29:13 1998).
* A bunch of varargs functions changed to get va_lists working on systems that
  implement va_lists as arrays.
* Improvements to the gdkrgb code.
* Improvements to Gdk color handling so we greatly reduce server traffic and
  don't leak colors anymore.
* Improved internal widget tree iterators (the GtkContainer::foreach signal
  vanished because of this).
* Option menus can have the keyboard focus now.
* More fixups to the text widget.
* GtkFileSelection should behave much more nicely in combination with AFS now.
* Support for label underlining.
* Support for GLib 1.1.3 log domains.
* Documentation improvements.

* Far better support for object arguments, revamp of the underlying
  mechanism for speed and reusability. Child/object arguments don't
  need to be preceeded by the "GtkType::" portion anymore.

* Overhaul of the resizing code. Resizing behaviour can now be specified
  on GtkContainer basis, so the underlying algorithm isn't only available
  for GtkWindows.
* GtkTables are now fully resizable.
* The GtkType system now supports an additional base class initialization
  function.
* GtkStyles and key bindings can now be looked up depending on the base
  types of a widget, through a new keyword `class' in rc files.
* GtkButton derives from GtkBin (finally).  
* More descriptive error messages on rc parsing.

  including those that already went into the 1.0.x branch.
* A big bunch of features and cosmetic fixups that just got lost in
  the masses of changes.
