A few days have passed since the version name 1.1RC3 disappeared from issue jira of JRuby. And, Charles Nutter posed what would be showstoppers for final RC verison, RC3 to jruby-dev ml. So, we could know JRuby 1.1RC3 is about to released in a couple of days.
How about JRuby engine? As far as I tested JRuby engine by using trunk version, JRuby engine should not need any bug fixes to catch up with a new release of JRuby. Updating README.TXT would be enough. Easy, this time.
