Ruby 1.8.6 and 1.9.0 Diff on Methods

I am waiting my friend install Oracle 10g on our Development Server in SLES 10, so I grab my intermediate file of my Ruby Doc Browser and Compare it with the Ruby 1.9, and this is the result (screen-shoot) in my Open Office

for String and Kernel CLASS have some good news since now the methods (gsub|! || chomp|! || chop|! || sub|! and scan / split) have the right place.
