The Jython development team has released the first alpha of Jython 2.5. The guys were hoping to have this done in time for EuroPython, but it wasn’t to be. Still, they are ahead of where they planned to be, so this is good news. If you are interested in an up to date version of Python on the JVM, go kick the tires and report bugs. Getting more testing done should help speed the process of shaking out all the bugs.
