      * New build 'warnings' [#117, !62, !63, Claudio André, Philip Chimento]
      * Various CI maintenance [!64, !65, !66, Claudio André, Philip Chimento]
      * profiler: Don't include alloca.h when disabled [!69, Ting-Wei Lan]
      * GNOME crash with fatal error "Finalizing proxy for an object that's
        scheduled to be unrooted: Gio.Subprocess" in gjs [#26, !70, Philip Chimento]
