A couple of years maybe. I think it happened at the same time we 
demanded that size(Rng) only worked for RandomAccessRanges and that this 
function also returns a signed type.

Using the old docs, one can probably track down the approximate time.

The bottom line is that it was a deliberate decision. The example put 
forward

   std::min(bbb.size(), (size_t)arr.size());

is not portable either.
