They are currently participating in the voting process for the next standard. You found drafts for C ++ 14.
From the warning on the first page of N3690:
This document is not an international ISO standard. It is distributed for viewing and comments. This topic is subject to change without notice, and cannot be called an International Standard. Recipients of this project are invited to provide with their comments a notice on any relevant patent rights of which they know and provide supporting documentation.
I guess the N3690 is the version they vote on, so it should look as close to the real thing as possible. Version N3691 will be the last working copy and is non-voting.
