Feel free to not put these things in, they are just the things that 
occur to me, of things I have been involved in :)

std::iter_swap (and therefore most of the mutating algorithms) now makes 
an unqualified call to swap when the value_type of the two iterators is 
the same. While not required by the standard, iter_swap will still work 
on proxy iterators as long as their their reference_type is not 
"value_type&".


Also, do you want to add something like:

No guarantes about the implementation of the code in TR1 is provided. In 
particular the final location of the headers and namespace in which they 
will be in has not been finalised, and it is not promised that 
libstdc++-v3 will remain link compatable when code using TR1 is used.

The link-compatable bit in particular I think about.. in particular 
tuple<> won't be link compatable if next version we give it a maximum of 
20 or 30 parameters, and if anything changes that might break things to...
