What is RSS - Archive of obsolete content
in august 2002 userland released a draft for rss 0.94.
...(although some were using rss 0.93 and rss 0.94 even though they weren't supposed to.) in september 2002 userland released rss 2.0.
... rss 2.0 was meant to be a replacement for rss 0.92 (and the rss 0.93 and rss 0.94 drafts that no one was supposed to use).

Version - Archive of obsolete content
note: rss 0.93 and rss 0.94 were only ever released as "drafts" and never became "final" and thus were not meant to actually be used.
