Version 1.57.91 - GJS no longer links to libgtk-3. This makes it possible to load the Gtk-4.0 typelib in GJS and write programs that use GTK 4. - The heapgraph tool has gained some improvements; it is now possible to print a heap graph of multiple targets. You can also mark an object for better identification in the heap graph by assigning a magic property: for example, myObject.__heapgraph_name = 'Button' will make that object identify itself as "Button" in heap graphs. - Closed bugs and merge requests: * Remove usage of Lang in non legacy code [Sonny Piers, !322] * GTK4 [Florian Müllner, #99, !328, !330] * JS syntax fixes [Marco Trevisan, Philip Chimento, !306, !323] * gi: Avoid infinite recursion when converting GValues [Florian Müllner, !329] * Implement all GObject-introspection test suites [Philip Chimento, !327, !332] * Heapgraph improvements [Philip Chimento, !325]
