What is the difference between Ruby 1.8 and Ruby 1.9

I'm not clear on the differences between the "current" version of Ruby (1.8) and the "new" version (1.9). Is there an "easy" or a "simple" explanation of the differences and why it is so different?

+14  A: 

Sam Ruby has a cool slideshow that outline the differences.

HTH!

One huge difference would be the move from Matz's interpreter to YARV, a bytecode virtual machine that helps significantly with performance.

Many now recommend The Ruby Programming Language over the Pickaxe - more to the point, it has all the details of the 1.8/1.9 differences.
