It's my impression that something in the handling of attributes by "[<-" has changed a bit between 0.62 and 0.63. I didn't notice any mention of this in the list of changes (except that subscripting has changed in other ways). Does someone know if this has changed, or should I be looking at things I've been messing with myself.
