JRuby 1.1 is the second major release for our project. The main goal  
for 1.1  
has been improving performance. We have made great strides in  
performance  
during the last nine months. There have been more and more reports of  
applications exceeding Ruby 1.8.6 performance; we are even beating Ruby  
1.9  
in some microbenchmarks. Please try your applications against JRuby 1.1  
and  
give us feedback. If you find poor performance or a compatibility  
problem,  
then we want to know about it; message us on IRC, email our mailing  
list, or  
file a bug.

Other major features include:

- Compilation of Ruby to Java Bytecode (in AOT and JIT modes)
- Oniguruma port to Java
- Refactored IO implementation
- Improved memory consumption
- Thousands of compatibility fixes

As always, the community has been the driving force behind JRuby’s  
progress.  
Thousands of reported issues and unending IRC conversations has helped  
keep  
JRuby focused on doing what is most important: Making Ruby applications  
work  
well. We want to thank all people who have helped and encouraged others  
to  
give JRuby a try. It is ready for production use today.
