On behalf of the Jython development team, I'm pleased to announce that Jython 2.5rc1 is available for download at http://downloads.sourceforge.net/jython/jython_installer-2.5rc1.jar. See the installation instructions: http://www.jython.org/Project/installation.htm. It contains bug fixes and polish since the last beta. One especially nice bit of polish is that JLine (http://jline.sourceforge.net) is enabled by default now, and so using up and down arrows should work out of the box. If no major bugs are found this release will get re-labeled and released as the production version of 2.5.0. Please try this out and report any bugs that you find: http://bugs.jython.org. -Frank
