Question

According to Jython’s documentation:

Jython is an implementation of the
Python language for the Java platform.
Jython 2.5 implements the same
language as CPython 2.5, and nearly
all of the Core Python standard
library modules. (CPython is the C
implementation of the Python
language.) Jython 2.5 uses the same
regression test suite as CPython, with
some minor modifications.

Are there any plans to support Python 3? If so, when is it scheduled to be released?

Answer 1

Jython roadmap is definitely outdated.
However, on Frank Wierzbicki’s Weblog (one of Jython’s main developers) you can get an update, telling that Python 3 is definitely on the radar.

Unfortunately, it is not yet clear when, as it is stated in a comment in that same blog from 2010:

Jython will reach 2.6 and later a 3.x,
but it’s hard to give a solid time
frame. I’m hoping to get a 2.6 out in
a few months.

In an interview in 2017, Wierzbicki stated that Python 3 is desirable but difficult.

Langfristig wollen wir eine 3.x-Version
veröffentlichen, aber das ist ein langwieriger Prozess, weil es eine
große Menge an Veränderungen in der 3.x-Serie gab.

English:

We want to publish a version 3.x in the long run, but that is a drawn-out
process, because there were a lot of changes in the 3.x series.
