Version 1.87.1
--------------

- In this alpha release for the GNOME 50 cycle, the main focus has been on
  modernizing the code base and making it more type-safe. Expect more of this in
  the beta release.

- We have better support for boxed C unions now in gobject-introspection.

- Gtk.Builder has gained some JS-only conveniences, which should make it less
  tedious to use from JS code.

  The following construct properties are now recognized:

  * "data" accepts a string or UTF-8-encoded Uint8Array containing Gtk.Builder
    XML, and automatically calls add_from_string().
  * "resource" accepts a string resource path, and automatically calls
    add_from_resource().
  * "filename" accepts a string filename, and automatically calls
    add_from_file().
  * "callbacks" accepts a property bag with properties equal to callbacks that
    are referenced in the Gtk.Builder XML.
  * "objects" accepts a property bag with properties equal to objects that
    should be exposed to the Gtk.Builder XML.

  Gtk.Builder has also gained a few JS-only convenience methods:

  * exposeObjects() calls expose_object() for each name and object in a property
    bag, much like the new "objects" construct property.
  * get_objects() overrides the original C get_objects() method, but on the
    returned array, additionally, there are named properties representing the
    exposed objects.

- Gio.ActionMap.add_action_entries() now supports additional types in its
  array of entries: GLib.Variant and GLib.VariantType. It also interprets JS
  values as unpacked GLib.Variants where appropriate.

- GLib.idle_add_once(), GLib.timeout_add_once(), and
  GLib.timeout_add_seconds_once() are now introspectable.
