Ruby, Rails: mysql2 gem, does somebody use this gem? Is it stable?

Question

I found mysql2 gem. It works fine with ruby 1.9 and utf8 encoding (as opposed to mysql gem).

A bit late - but I'm using mysql2 in production on a couple of sites, and have found it very stable since some issues with connections getting closed were resolved a few weeks ago.
