- Replace pkgconfig(giomm-2.52) with pkgconfig(giomm-2.54)
  BuildRequires following upstream changes.
- Add explicit pkgconfig(glibmm-2.54) BuildRequires: Configure
  checks for it.

- Update to version 3.89.5:
  + Gtk:
  - AboutDialog: Add a constructor with a use_header_bar
    parameter(bgo#780004).
  - AccelMap: Change accel_path method paramters from std::string
    to Glib::ustring, because there are always UTF-8.
  - Assistant: Add child properties and a constructor with
    use_header_bar.
  - Dialog: Simplify the constructors: Remove constructors that
    take DialogFlags. Add an optional use_header_bar parameter to
    the other constuctors. There is now no way to specify the
    GTK_DIALOG_DESTROY_WITH_PARENT flag, but hopefully this is
    not used much anyway (bgo#780004).
  - ScaleButton: Let get_[plus,minus]_button() return Button*.
  - Move PageRange out of PageSettings.
  - RecentManager: Remove unused SlotChanged.
  - TreeIter<> (TreeModel::iterator/const-iterator): Fix
    operator==() and operator!=() comparisons of const and
    non-const iterators (bgo#134520).
  - TreeModel: Use const_iterator for some vfunc parameters.
  - TreeModel::Path::get_from_selection_data(): Make the
    TreeModel parameter const.
  - Tree*, ComboBox*: Change some parameters to const_iterator.

  + Gdk:
  - Pixbuf:
    . Throw exception from ctor instead of creating invalid
    object.
    . Add get_pixels().

  - Window: constrain_size(): change the flags parameter from
    guint to WindowHints.
  + Build: Visual Studio builds: Require Visual Studio 2017.

- Update to version 3.89.4:
  + Gtk:
  - Add Gtk::WidgetCustomDraw and WidgetCustomSnapshot. These
    make it possible to use signal_draw() and snapshot_vfunc() in

    visible by default, unlike in gtkmm 3).

    . Remove add_gtk_option_group().
  - ToggleButton:

    default, unlike in gtkmm 3).

  + Gtk:
  - Grid: attach(): Add default values.
  - TextIter:
    . Make a real const_iterator (bgo#142126).
    . forward/backward_find_char(): Take a sigc::slot instead of
