Jython 2.5.2 RC3 Has Been Released

The Jython development team proudly announced the release of Jython 2.5.2 just ahead of PyCon 2011. This release is packed with bug repairs and quite a few enhancements to make Jython even better.

New Features

* The socket module now includes ipv6 support

* The socket module now also includes Internationalized Domain Names (RFC 3490) support on Java 6

* Performance improvements around method invocation. 2.5.2 runs the richards benchmark 3x faster and the pystone benchmark 20% faster than 2.5.1

* The posix/nt module was rewritten in Java and the performance of its often performance-critical stat function has significantly improved

* Improved OSError errno messages on Windows

* Slightly improved startup time (ongoing Issue #1380)

* Better readline module emulation (required for IPython support)

* Python functions can be directly passed to Java methods that take a single method interface (such as Callable or Runnable)

* Google indexer

* Lots of bug fixes!

Please go the Jython downloads and grab the release today!

Jython 2.6 Development Underway

There was a Jython sprint at PyCon 2011 in which the developers were able to get underway with 2.6! If you are interested in viewing the roadmap or contributing to the release, please check out the roadmap on the wiki to see what is actively being worked on at this time!

Django-Jython 1.2.0rc1 Has Been Released

The Django-Jython project has made release 1.2.0rc1 available. This release contains a handful of bug fixes since the 1.2.0b1 release in early March. The Django-Jython project is on- target to release 1.2.0 FINAL by the end of March given that no show stoppers remain within the bindings. There have been a couple of issues found regarding the use of the interactive console in Windows environments as well as the creation of superusers on Windows. However, these issues have been found to be linked to Jython proper, so there will have to be some work done there to repair the issues. I am on this issue at this time and will send updates to the Jython and Django-Jython developer mailing lists.

Django 1.3 Has Been Released

Altough not directly related to Jython, the Django web framework has released version 1.3 this past week. The overview states:

Django 1.3’s focus has mostly been on resolving smaller, long-standing feature requests, but that hasn’t prevented a few fairly significant new features from landing, including:

A framework for writing class-based views. Built-in support for using Python’s logging facilities. Contrib support for easy handling of static files. Django’s testing framework now supports (and ships with a copy of) the unittest2 library. There’s plenty more, of course; see the coverage of new features below for a full rundown and details.

To download the latest release, please visit the Django download page.

The Django-Jython project is currently running tests against the Django 1.3 codebase and plans to release a beta for Django-Jython 1.3 as early as next week. Please download Django-Jython 1.3b1 once it is released and test!


The Prevalance of Non-Java languages on the JVM

The current Java.net poll is showing some interesting early results. With the number of responses approaching 100 so far, the poll question How much of your JVM-based programming is in languages other than Java? reveals that just over half of the respondents replied "All my JVM programming is in Java." In my experience, an even higher percentage of Java developers do not do any "JVM programming" outside the Java language itself. However, I'll admit that I had expected more than half of the respondents to a Java.net survey to be regular users of JVM languages other than Java. There has always been a disconnect between the everyday Java developer and the Java developer who regularly reads and responds to online Java community resources such as Java.net.
