+Version 1.57.90
+---------------
+
+- New JS API: GLib.Variant has gained a recursiveUnpack() method which
+  transforms the variant entirely into a JS object, discarding all type
+  information. This can be useful for dealing with a{sv} dictionaries, where
+  deepUnpack() will keep the values as GLib.Variant instances in order to
+  preserve the type information.
+
+- New JS API: GLib.Variant has gained a deepUnpack() method which is exactly the
+  same as the already existing deep_unpack(), but fits with the other camelCase
+  APIs that GJS adds.
+

+  * Marshalling of GPtrArray broken [#9, !311, Stéphane Seng]

+  * GLib's VariantDict is missing lookup [#263, !320, Sonny Piers]
+  * toString on an object implementing an interface fails [#252, !299, Marco
+    Trevisan]
+  * Regression in GstPbutils.Discoverer::discovered callback [#262, !318, Philip
+    Chimento]
+  * GLib.Variant.deep_unpack not working properly with a{sv} variants [#225,
