Rubygems 1.4 will not support Ruby 1.8.6

Eric Hodel writing a week or so ago:

Ruby 1.8.6 is old and it’s API is lacking the forward-compatibility that Ruby 1.8.7 has for moving to Ruby 1.9. Since I maintain two large ruby libraries that are shipped in 1.9 (RDoc and RubyGems) it is becoming hard to maintain 1.8.6 support inside them comfortably.

…

RubyGems 1.4.x will not support Ruby 1.8.6.

Seems eminently sensible.
