[jbpm-dev] [Design of JBoss jBPM] - API first cut available for jBPM3

[Tom Baeyens]

The scope of jBPM 3 work is already way beyond the resources we have for it.  We 
should focus on the necessary work to put jBPM 3 in maintenance rather then 
introducing a new API on it.

We said in the meeting in the context of the migration debate that no API will be 
introduced in jBPM 3.  A new API will be introduced in jBPM 4.

regards, tom.
