In April 2013, IBM announced that the WebSphere Message Broker product was undergoing another rebranding name change. IBM Integration Bus version 9 includes new nodes such as the Decision Service node which enables content based routing based on a rules engine and requires IBM WebSphere Operational Decision Management product. The IBM WebSphere Enterprise Service Bus product has been discontinued with the release of IBM Integration Bus and IBM is offering transitional licenses to move to IBM Integration Bus. The WebSphere Message Broker Transfer License for WebSphere Enterprise Service Bus enables customers to exchange some or all of their WebSphere Enterprise Service Bus license entitlements for WebSphere Message Broker license entitlements. Following the license transfer, entitlement to use WebSphere Enterprise Service Bus will be reduced or cease. This reflects the WebSphere Enterprise Service Bus license entitlements being relinquished during the exchange. IBM announced at Impact 2013 that WESB will be end-of-life in five years and no further feature development of the WESB product will occur.
