Hello JPython users,
I'm very happy to announce the formation of the Jython project on SourceForge. Jython is the successor to JPython, the Java implementation of the Python programming language. We've created this new project in accordance with the CNRI JPython 1.1.x license, in order to ensure the continued existence and development of this important piece of Python software. The intent is to manage this project with the same open policies that are serving CPython so well.
Finn Bock and I have been working on the next release, to be called Jython 2.0. Finn has integrated his JPython errata, and Python 2.0 language features such as augmented assignments, list comprehensions, and extended print have also been added. The free Apache Jakarta OROMatcher software has taken the place of the previously non-free OROMatcher code for regular expressions, so there will be no further need to dual license. Jython 2.0 will eventually be released with a license similar to CPython 2.0.
I don't know when the first alpha release of Jython 2.0 will happen, but all the code is currently available in the SourceForge CVS tree. I will also be converting the old Jitterbug database to the SF bug tracker as soon as possible.
I've created several mailing lists to support Jython development:
This list will supplant email@example.com and should be the general discussion list for Jython users.
This is an analog to firstname.lastname@example.org, except that it will have an open subscription policy. This is the place for Jython developers to discuss and help move the Jython project further.
A low-traffic, announce only list.
Similar to email@example.com, this list will receive CVS checkin and diff messages.
All these mailing lists, and all current information on the Jython project is available at SourceForge, at
I will not be automatically subscribing any current jpython-interest members to the new lists; that's up to you.
I know Finn joins me when I say that we look forward to working with you on Jython, and to your contributions in furthering this project's development.
