[math] Why is version 2.2 not linked to as the current version of Math?

[Stephen Nelson Lee]

Hi all,
Why is version 2.2 of Apache Commons Math all but not linked to at all from
the math home page <http://commons.apache.org/math/index.html>? The link for
the latest release points to version 2.1 and the 2.2 javadocs are not linked
to in the sidebar. I downloaded 2.2 back when it was linked to from the home
page, so I am wondering whether there was any reason why links to it seem to
have been removed.
Thanks,
Stephen Lee
