[boost] Where are the previous versions in the repository?

When checking one of my tickets, I noticed that the <http:// svn.boost.org/trac/boost/browser/tags/Version_1_34_1/boost/boost/ typeof/int_encoding.hpp> link had gone bad. Looking at <http:// svn.boost.org/trac/boost/browser/tags>, I notice that _all_ of the tags for previous releases are gone. Why? (If they've been moved instead, let us know where they've gone.) -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
