What is the oldest version of rubygems that still allows you to download gems from rubygems.org?
+1
A:
When the transition from http://Gems.RubyForge.Org/ to http://RubyGems.Org/ was made, all backwards-compatibility features that were removed had already been replaced before RubyGems 1.0. So, you should be fine at least as far back as 1.0, possibly even further.
I'm not 100% sure, though. But I think that all that was removed was the YAML index format and bulk updating, both of which have been obsolete for years.
