BPEL stands for Business Process Execution Language, and determines how a set of services interacts as a single process.
The release includes side-by-side support for both BPEL4WS 1.1 and an early version of WS-BPEL 2.0. It also has JMX-based administration and management, pluggable persistence, a microkernel-style runtime suitable for standalone operation or embedding within an application server, connected debugging, and a set of commandline tools and Ant tasks for most common operations.
