N3290, which is protected, is considered by the committee to be the final draft. I have not purchased the ISO/IEC standard and compared them to ensure that it is identical to N3290. I have also not heard any discussion on the committee questioning that it is identical.
I've compared the cross references of N3290 and N3337. The cross references contain a complete list of the section.tags and section numbers. They are identical except for two minor changes:
N3290 has:
unord.map.modifers 23.5.4.4
unord.multimap.modifers 23.5.5.3
N3337 has:
unord.map.modifiers 23.5.4.4
unord.multimap.modifiers 23.5.5.3
(modifers -> modifiers)
I do not know about paragraph numbers. But here is a report from the editor concerning the changes made since the final draft.
