Not yet, as the latest C++ standard still dates back to 1998.
However, library extensions are actively being worked on,
and the boost.org repository of libraries

Some extensions are already "approved" for future inclusion,
and even supported by a fewcompilers in their preliminary form (the
recommendation for now being to keep these extensions in std::tr1).
See:

http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/papers/2003/n1540.pdf

Boost users will find a few familiar classes in this round of
proposed extensions, and probably in the next ones...

This is yet another reason to get familiar with these
peer-reviewed libraries.

I guess "singleton" is now the standard name for that,
probably from _Design Patterns_ by Gamma et al.

So no new stuff this time around.

I always seem to get lost maneuvering around there :)

Yeah, it will be interesting to see what makes it into the Standard.

ISO/IEC 14882:2003, you mean? It dates back to 1998 in the
sense that it replaces ISO/IEC 14882:1998 by incorporating
a number of corrections. No new features though.
