The project roadmap is published in our issue tracking system. We update it regularly to keep our community informed of the status of the project.
Earlier versions of the BPEL distribution up to 1.1.Beta2 were released under an LGPL variant with several major ammendments to fit the licensing terms of the BPEL specification, hence the 'custom' denomination.
Future versions will switch to CPL v1.0 because it fits the specification licensing terms better. Please read the JBoss EULA for more details.
