The current semantics would implicitly attach the most recently attached buffer at commit time and send a release event when the buffer enventually was released. The implicit attach is a little too subtle though and this patch changes the semantics to always only send release events in response to an attach event. As a consequence, once a compositor releases a buffer, it no longer has a reference to it and wl_surfcea.damage is undefined. Thus, the client side visible change is that damage request must always be preceeded by a wl_surface.attach request, to ensure there's a valid buffer, even if that means attaching the same buffer again.
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
