ENTSOG has published an update version 3 of its AS4 profile on its Web site. This version contains some updates made in response to implementation experience. The main new feature is the requirement to support the recent OASIS ebCore Agreement Update (AU) specification for certificate updates. There is also an update for the "How to Set Up an AS4 System" document. It has new content that explains in more detail how users can configure processing modes for the ENTSOG AS4 profile and the ENTSOG AS4 mapping table. The document also shows how the ebMS3 test feature and ebCore AU can be used together to update AS4 configurations.
