It is documented in usrguide.dvi, though. And the following test:

  \documentclass{article}
  \usepackage{amsmath}[2005/01/01]
  \begin{document}

  Hello.

  \end{document}

yields on console:

  LaTeX Warning: You have requested, on input line 2, version
                 `2005/01/01' of package amsmath,
                 but only version
                 `2000/07/18 v2.13 AMS math features'
                 is available.

So, what's the problem?
