[Vala] [Announcement] Vala will use GTask for async code instead of GSimpleAsyncResult if --target-glib=2.36 or greater is selected

[Al Thomas <astavale yahoo co uk>]

A patch to Vala's master development branch was made this weekend. The patch changes the C code generated 
from Vala's async code. Future versions of Vala (0.36 and above) will use GLib's GTask instead of 
GSimpleAsyncResult when --target-glib=2.36 or greater is selected. Vala 0.36 is expected with GNOME 3.24 in 
March 2017. The patch is:

Thanks to Carlos Garnacho for the main work on the patch, to Ben Iofel for fixing cancelled tasks and to 
everyone else who tested and fed back on the patch. To see more details of this example of collaborative
