OpenWFEru is an open source Ruby workflow / BPM engine.

This release focused on porting the old (2003) REST interface of OpenWFE to OpenWFEru. Done for the worklist. Will be done later for the engine REST interface.
It means that you should be able to use openwfe-python, openwfe-dotnet, openwfe-pnuts and more, to access OpenWFEru.

The next big feature is the replay_at_last_error(wfid) method of the journal, it's detailed at http://jmettraux.wordpress.com/2007/06/04/replay_at_last_error/ and http://openwferu.rubyforge.org/journal.html#at_error

The methods of the scheduler have been simplified, but this change should not affect most of the users.

Implemented the 'listen' expression, for intercepting workitems getting to/back from participants, read more on that at : http://jmettraux.wordpress.com/2007/05/29/listen/
