The most recent version of the proposal is n2115:

<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2115.pdf>

You can follow the current state of proposals by looking at the 'State
of C++ Evolution' paper, the most recent of which, n2142, is here:

<http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2007/n2142.html>

This says the auto / decltype syntax is "undergoing final scrutiny in
Core Working group, and [has] been reviewed at least once".

This paper says:

The new function declaration syntax
auto f(params) -> return-type
that moves the return type after the function's parameter list is not
part of the wording. There will be a separate
document for that functionality.

However, there is still no such document. Even though N2115 is more
than 4 months old.
That's why I'm wondering what happened to the new function declaration
syntax.

This is not the latest one.
The latest one is N2169 :

What happened to the proposal for auto as a return value?
It was something like this:

auto f() -> decltype(some_expression)
{
     function_body
}
