The download links were removed on purpose, primarily such that devs do not need to answer/troubleshoot problems about 2.01 or earlier versions even after hashcat 3.00 with many changes was released. The idea is that as many users as possible use the new version and we keep improving that version (and of course focus on 3.00 and newer).
