Version 1.17.0

Release Date: July 25, 2026 Release Type: Release Candidate

This was a Release Candidate published to the staging channel; its content was validated and is included in 1.18.0, the first release on the single product version line. The headline of this release is native XI 3.0 messaging — an always-on inbound listener, reliable asynchronous EO/EOIO messaging and outbound XI requests, together with the matching XI Proxy flow connectors and systems registry.

New Features​

  • XI 3.0 inbound connectivity: MIP can receive XI 3.0 messages directly from partner registry/business systems through an always-on inbound listener on a configurable public path (default /XIMIP). It parses XI 3.0 envelopes, resolves the sending and receiving parties, routes each message to the correct flow, and replies with standards-compliant acknowledgements and faults. Error handling is fail-closed, so a message is never falsely acknowledged, and rejections (unknown binding, malformed envelope, authentication failure) now appear in Message Monitoring with an actionable explanation.
  • Reliable asynchronous XI messaging (EO / EOIO): Asynchronous XI messages are accepted into a durable inbox and persisted before being acknowledged, so no message is lost under failure. Exactly-Once deduplicates repeats and Exactly-Once-In-Order keeps strict per-queue ordering, with safe handling across multiple server nodes, automatic cleanup of old records, and flow-declared ordered-queue names. A background worker sends acknowledgements back to the sending system using pooled credentials, and each message is linked to its Message Monitoring record.
  • XI 3.0 outbound requests: A new flow step sends XI 3.0 requests to a registry/business system selected by name, supporting Best Effort and Exactly Once quality of service with automatic retry on transient failures, and returns the peer's response into the flow.

New Features​

  • XI systems, queues and proxy receiver: Register XI business systems, monitor XI inbound queues with retry and cancel, and use the new XI proxy receiver step.

Frontend Web​

New Features​

  • Design flows directly from XI (ESR) interfaces: New inbound and outbound XI Proxy connectors let you build flows straight from interfaces in the Enterprise Services Repository — pick an interface, target a registered system, choose its WSDL source, bind sender/receiver party-service, and set EOIO queues, all from a searchable catalog tree grouped by software-component version and namespace.
  • XI systems registry and queue monitoring: A new administration area to register XI/PO systems, manage a shared credential pool and business-party bindings, copy an existing system definition, run detailed connection tests, and monitor message queues.

This is a Release Candidate (pre-release); its validated content ships in 1.18.0. Previous: 1.16.6
