Wayland 1.0.4 was released this week along with an adjoining update to its Weston reference compositor. Separately, a new patch-set has emerged for supporting per-output workspaces.
The Wayland/Weston 1.0.4 release was a bit behind schedule due to Kristian Høgsberg being ill, but the point releases are out now for those interested. The main 1.0.4 change is for Weston and it's to address a "CPU eating bug" within the compositor's plane code. There's also been a few documentation fixes. With Wayland 1.0.4, destroy signal APIs were added and a more robust version of the event loop test case.

Separately, a set of 11 patches for Weston made it out this morning by Jonas Ådahl. These patches add per-output workspaces to the Weston desktop shell. "This series adds per-output workspaces to the desktop shell of weston. The major change is how toplevel surfaces are managed by the shell plugin. Before, surfaces were always kept in layers and workspaces was implemented by attaching/detaching layers associated with workspaces." The patch series begins here
Last but not least, for more recent Wayland news reading, there is Kristian's patch queue + signs of life
