On May 10, 2004 the stable-snapshot was still Ruby 1.8.1.

Yesterday, the stable-snapshot is Ruby 1.8.2.

Before I saw this change, I was under the impression that 
stable-snapshot is more reliable/stable than the stable-release 
(currently 1.8.1).  Am I mistaken?

Which is more reliable/bugfree?  Ruby 1.8.1 release or stable-snapshot 
(1.8.2)?
