Wrapped up yesterday evening Chicago time, arrived on CRAN this morning,
CRANberries chronicles this well.  I'll blog the announcement this evening...

Yes. A few things:

 a) binary interfaces changed; modules package are borked; other packages
    most likely too; so what you have installed you may need to reinstall

 b) as we learned from Kurt, we broked RcppEigen and (the less widely used)
    RcppOctave, maybe more; we are looking into this

 c) on the bright side, cda builds again :) and there are a lots of new
    features and fixes

I am at work so no more detail now.

Right.

May need refreshed template magic. To be seen.

Roll back to 0.10.0 then if that works better for you.

Sorry about the breakage.
