the core interface specification and headers have changed between 1.0 and 1.2. Plugins need to be recompiled against the 1.2 headers to work with the new version.
There’s currently a bugfix+minor update version of WM in progress (1.3) that should be released before Christmas. Rather than releasing the 1.2PDK headers now, I’m currently planning on releasing the 1.3 version of the PDK that also features much more in the way of documentation on creating a plugin, and helper features that make it easier to create specific types and features in your devices.
