I'm aware of a fork called Fusilli[2] that is a continuation of 0.8 with some redundant features removed. Otherwise, if I were to give an objective assessment of 0.9, I'd say that with the right skill set moving the older plugins over to using modern OpenGL is not particularly hard. Probably one of the hardest was the blur plugin and that only took me a day or two[3]. The three biggest changes to rendering were 1. The move to triangle-based meshes as opposed to relying on quads. 2. The move from assembly fragment programs to GLSL. 3. The move to using SwapBuffers (with GLX_EXT_buffer_age) as opposed to CopySubBuffer. 1 & 2 are API-incompatible changes. 3 is a change that silently exposes bugs in existing plugins, usually relating to a failure to indicate update regions on the screen. In terms of Wayland, I'd honestly recommend look into using something like libweston and putting a "compiz plugins" compatibility layer on top of it. That all depends on what compiz plugins actually rely on from core, but for about 90% of them, not much. Having a GLES compatible codebase also helps there too, if that's a road one feels like going down.
