Jython 2.5 Beta0 is the beginning of a code cooling period where the number of new features should significantly slow as we concentrate on solidifying Jython 2.5 for an eventual release. There are still a number of features that we will squeeze in (like jythonc).
This is a beta release so be careful.
I tried it out on my Debian GNU/Linux 4.0 x86_64 machine with OpenJDK 6. Everything from my March 2001 JNB article on Scripting Languages for Java still works, including the Turtle example:
Oh, boy. This brings back old memories. That article was listed on the old Jython website as the first few "press mention" of Jython. That was five months after the Jython project was announced. And the jython interpreter bore this version number:
Jython 2.0 on java1.2.2 (JIT: sunwjit)
While the jython folks were thrilled that they got anther press mention, I was thrilled to be called "press". Of course at the time I have no way of knowing that Jython will go through several years of slow progress. I am very happy to see the attention Jython has gotten lately and am looking forward to Jython 2.5 final release early next year, and the Jython 3.0 that's going to come after.
