+Subject: [PATCH] introspect: Add WindowsChanged signal
+
+The screencast portal supports recording a single window,
+and presents a list of open windows when that option is
+selected. To allow updating that list when windows are
+opened or closed, add a new "WindowsChanged" signal that
+the portal can listen to.

+Subject: [PATCH] window-tracker: Emit 'tracked-windows-changed' on title
+ changes
+
+This means the screen share window view gets updated also when the title
+of a window changes. This is important since it often changes shortly
+after mapping, which would otherwise go unnoticed by
+xdg-desktop-portal-gnome.
+
+An example is launching Files and it showing up as 'Loading..', or
+launching a terminal, and it not showing the proper title (current
+directory), but some place holder that is never visible on the
+application window.
+
+Adding it to the window tracker instead of in introspect.js itself is
+for convenience - there is no per window signal tracking there, and it
+already listens to the signal emissions about changed windows.
