maybe some of us found that any previous release of wordpress is difficult to locate, like me, this site was in wordpress 1.5 series and i want to upgrade it to latest release of 1.5 series, but when i go to download section at wordpress site, it show just the latest release of wordpress (in fact it was 2.0 release) that i dont need it now.
as i search in the google, i found that any wordpress releases was archived in http://static.wordpress.org/archive/
so if your wordpress 1.5 series is outdated, u better download and upgrade it to the latest from that archive, like me do… 
upgrade to 2.0 series is not necessary yet, i think, maybe i wait it a time before i do…
viva wordpress !!!
