Add-on packages such as FCRepoKepler must be put in the user's home directory under the Lib directory. For example, on a Windows box, this would be C:\Documents and Settings\username\Lib.

Kepler 2.0 (dev)

PythonActors use the Jython 2.5.1 interpreter which implements a most of the Python 2.5 language. See Is Jython the same language as Python for details. This is a significant improvement over the version of Jython supplied with Kepler 1.0.

Add-on packages such as FCRepoKepler must be put in the Kepler installation directory under the core/lib/jar/Lib directory.

Kepler 2.0 is very promising with a lot of features that will help our project but it has proven to be very buggy at times.

PythonActors use the Jython 2.5.1 interpreter which implements a most of the Python 2.5 language. See http://wiki.python.org/jython/JythonFaq/GeneralInfo#IsJythonthesamelanguageasPython.3F for details. This is a significant improvement of the version of Jython supplied with Kepler 1.0.

make life easier for projects that need to extend Kepler's functionality. Most important is the updated module management system that allows new features to be loaded at runtime rather than requiring complete rebuilds from source.

There are several new actors available and the PythonActor is fully integrated into the Kepler actor database. This has improved much of the flakiness seen when using PythonActors in Kepler 1.0. NOTE using Kepler 1.0 to open a workflow that was saved in Kepler 2.0 can cause PythonActors to lose their scripts. Reopening these workflows in Kepler 2.0 will NOT fix them, the scripts must be re-entered from some external source.

Kepler 2.0 is still in development and changes daily, so it has proven to be very buggy at times. On the other hand, the development team does a very good job of letting the community know about critical bugs and then fixing them quickly.

The targeted release date now appears to be early 2010. The Kepler 2.0 Release Roadmap discusses details of what will be included in Kepler 2.0that release.
