JRuby 1.5 is now available and includes 1,300 revisions and 432 bug fixes. The latest version of the Ruby variant that runs on Java Virtual Machines has been designed to “integrate well with the rest of the Java ecosystem,” explained project leader Charles Nutter. “Lots of Java libraries really need to have regular Java classes that they can use. Now it’s possible to write those in Ruby using JRuby.”
The new release of the open source language also offers better Windows support.
