I don't see anything below that is new today.  Are you saying you didn't 
test any of the pre-release versions?  You're basically stuck with the 
features that come out in .0 releases until the next one.  I'll fix the 
typo in 4, but the rest of it is unlikely to change much in the next six 
months.
