-- Update to version 2.21.5:
-  + Adapt to recent GDK and Gtk+ deprecations.
-    You may need to include gtkmm/box, gtkmm/dialog.h,
-    gtkmm/main.h, gtkmm/treepath, or gtkmm.h before other gtkmm or
-    gtk+ includes to build with disabled deprecations and warnings
-    as errors.
-  + PrintOperation: get_default_page_setup(): refcount fix.
-    bgo#622957
-- Changes from version 2.21.1:
-  + atkmm is now a separate tarball module.
-  + Remove support for these glibmm build options via ifdefs:
-    --enable-api-exceptions
-    --enable-api-properties
-    --enable-api-default-signal-handlers
-    (All this gtkmm API is now always present.)
-  + Assistant: Added commit().
-  + Entry: Added im_context_filter_keypress() and
-    reset_im_context().
-- Add atkmm-devel BuildRequires and remove update-desktop-files
-  BuildRequires.
-- Remove explicit Requires from devel package: they will get
-  automatically added with pkgconfig()-style Requires.
-- Respect the shared library packaging policy and create a
-  libgtkmm-2_4-1 package.
-- Fix self-obsoletion issues, to make rpmlint happy.
