ok, this sounds like a good plan. Do you want to make this happen
before the release of 0.7.0?

There are a few things left on my TODO list, but most of them involve
cleaning up:

 1. Make sure all demos work
 2. Make sure manual is current (but not necessarily complete)
 3. Same for UFC and FFC
 4. Get mesh partitioning working
 5. Recompile all forms with latest FFC (0.4.0) and UFC (1.0)
 6. Some minor fixes

Anything else?

Except for updating the manuals, we could have the new release ready
this week.

I expect we need to leave a few things for future releases:

 1. Adaptive mesh refinement/coarsening. What's the status?
 If it's not working, I'll remove the demos for it.

 2. Getting linear algebra, PDEs etc running in PyDOLFIN.

 3. Parallel assembly.

Should we decide on a feature freeze by Friday, so we'll have a few
days to test it compiles etc. before we make the release?
