MantaRay is a distributed, peer-to-peer, server-less communication & messaging solution. As a result of community feedback, MantaRay 2.0 is release under the Mozilla Public License (MPL) instead of the previous GPL.
Likewise, all of the MantaRay 2.0 companion products are now available to the open source community under an MPL license. Additionally, hooks have been incorporated to enable pluggable implementation of authorization and authentication security. A dead letter destination now handles deprecated messages. Improved JCA implementation and minor bug fixes are integrated into this release as well.
