FWIW, while I've not been following this /too/ closely (as my use-case 
has zero reason to do a convert), I believe I saw Chris and others 
discussing the patch, and I /think/ it (or an update) may have actually 
been in the 4.1 upgrade window pull.

Presumably they'll queue it for stable too, once it's in 4.1 (or whatever 
if I'm wrong on the 4.1 pull).

A verify either way would be useful, but as I said I've not been 
following it /too/ closely, and I'm still on 4.0 here, so...
