+- Update to version 2.52.0:
+  + Gio: UnixSocketAddress::create(): Remove the default value for
+    the type parameter to avoid ambiguity (bgo#782592).

+    (bgo#781818).
+  + Documentation: RefPtr: Clarify comment about undefined
+    behaviour.
+- Changes from version 2.51.7:
+  + Glib:
+    - SettingsSchemaKey: Add missing value/range methods
+      (bgo#774903).

+      to fix the build with C++17 (rh#1438766).
+    - VariantType: Deprecate first() and next(). Add
+      get_item_types() (bgo#775741).
+  + Gio:
+    - ActionMap: Add add_action_with_parameter() that takes a
+      parameter type, and deprecated the existing method, because
+      it cannot work (bgo#774444).
+    - SimpleAction: Make set_state() public (bgo#777953).
+  + Build:
+    - MacOS: Correct build without gdesktopinfo (bgo#781947).
+    - Glib::Object: Suppress deprecation warning for
+      g_object_newv() with glib 2.54.
+- Changes from version 2.51.6:
+  + Glib:
+    - Dispatcher:
+      . autodeduce the type of the fd field (bgo#772074).
+      . Don't cast a HANDLE to an int on Windows (bgo#772074).
+    - ustring: Add cbegin() and cend().
+  + Gio:
+    - Action: Include variant.h in the heaer (bgo#777953).
+    - Application: get_default(): Correct the reference counting
+      (bgo#779936).
+    - Settings:
+      . Really add set_enum() and set_flags() (bgo#774647).
+      . Writable-change-event signal: Correct the type of the key
+        parameter (bgo#773977).

+    get_cached_property_names() (bgo#775210).
+  + Documentation:
+    - Glib::Variant: Improve documentation of maybe types
+      (bgo#778219).
+    - Gio::ActionMap: Clarify doc of ActivateWithParameterSlot.
