Jruby is a project to provide a Java implementation of the Ruby language and 
interpreter.

Jruby 0.8.1 has been released.  This version is a smattering of smaller
fixes.  Some more visible changes include:

- Some java interfaces are being adorned to quack like some ruby counterparts
  (for example, java.util.List includes Enumerable and '<<' method)
- Java bean properties can be referred to by name (a.getPhone can be a.phone)
- Several constant scoping issues have been resolved

Thanks to all people on the project and mailing lists for making jruby a much 
better piece of software.

Changes since 0.8.0:

- Constants assigned nil will not throw an error
- Regexp embedded comments work now
- Wrong arity was not always throwing an error for methods, procs
- Method and UnboundMethod were mistakenly named RubyMethod and RubyUnboundMethod
- Fix 'def f; yield; end; f {|*a| p a == [] }'
- Fixes 'x, (y, z) = 1, 2, 3; test_ok([1,2,nil] == [x,y,z])' and variants
- Kernel#exit does not print stack trace on exit
- Kernel#exit now returns 1 by default and it properly handles a boolean arg
- Change Array.[m..n] where m > n now returns []
- Hash#default= should override constructor provided block
- Procs sometimes had returned to wrong location
- Java integration features (<=> for Comparable, etc...)
- Support def foo(*); end
- Missing version spec for java 1.4 in ant java docs task (thanks to Kazuhiro Oinuma for noticing this)
- /x\d\d? in regexps not supported
- Support $: in jar files
- Make 'require' not include a directory as if it were a file
- Add file? to File, FileTest, File::Stat
- File#basename converts arguments via to_str
- Fix File#basename to allow suffix '.*' and to remove trailing slashes
- File#truncate and File.truncate should convert numeric argument via to_int
- File#dirname should convert string via to_str
- Fix ::CONSTANT lookup (colon3)
- Fix Duplicate named constants in different namespaces from c- Constants included in Modules should be found by includer
- Enumerable#each_with_index should return self
- File::Stat was not defined under File and was not called Stat
- $SAFE=3; $SAFE=2 yield java exception and not ruby one
- Add Proc#to_proc and make dup work for blocks
- Support java bean properties better in Java support (uses Introspector)
- Change LoadService to allow jars to find subdirs within classpath
- File::Stat not under 'File' and is not called 'Stat'
- Add missing Fixnum.div
- Add support for $~
- java exceptions can be rescued
