The JRuby 1.1.1 release provides mostly bug fixes for JRuby 1.1, like a fix for a bug causing problems with IBM JDKs. See the release notes for a complete list of bug fixes and improvements.
--profile flag. This launches JRuby with JIP - The Java Interactive Profiler enabled. JIP is now part of the JRuby distribution and comes with configuration to make it work with JRuby's class loaders (JIP works using Java's instrumentation feature which allows modification of bytecodes). Note: JIP profiles the bytecode of the JRuby runtime and the bytecode generated at runtime.I just committed a change to the JRuby startup scripts that boosts startup speed by almost 70% (for me). It loads the JRuby jars (and CLASSPATH) into bootclasspath instead of normal classpath, bypassing verification (and apparently other things, since this is way faster than -Xverify:none). It should also be a safe change; JRuby's core should have been verified a kajillion times before release, and code generated at runtime will be verified as normal.JRuby is also represented in the Google Summer of Code (GSoC) 2008 with a few projects:

"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?
Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.
Heroku's Adam Wiggins talks about Rails, Background Jobs, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
