Version 1.16.0

Release Date: July 24, 2026 Release Type: Stable (LTS)

Flow Simulation: Run a flow without sending real messages — simulate it end to end or only up to a selected end node, with per-step input/output capture, live progress streaming and mockable HTTP/SOAP responses.
X.400 connector: New X.400 P7 sender and receiver connector.
EDI Converter connector: New unified EDI converter connector with EDI schema management.
Global flow configuration: Define configuration shared across flows, with per-flow overrides applied at runtime.
Flexible route authentication: Select multiple authentication types per route, with added OAuth2 token introspection support.
OAuth2 JWT client authentication: Outbound OAuth2 connections can authenticate with a signed JWT client assertion (RFC 7521/7523) instead of a client secret.

Guided import with conflict resolution: Package and flow-mapping imports now run analyze → preview → apply, showing conflicts up front and letting you decide per item (overwrite or skip; conflicting packages can be merged or skipped); exports carry the global flow configurations a flow references.
Global flow configuration management: Manage shared flow configuration with per-flow overrides.
Flow Simulation history: Simulation runs and their mock libraries are saved for later review.
Flexible authentication: Multiple authentication types per route, OAuth2 support and JWT client assertions reflected across the server.
X.400 support: Server-side data model for the new X.400 connector.

Flow Simulation panel: Redesigned simulation panel with a Mock Responses tab, the ability to run a flow or a partial flow up to a selected end node, live node coloring on the canvas during a run, and per-step execution timing.
X.400 connector UI: Designer node panels for the new X.400 connector.
Import conflict resolution: New conflict dialog during package and flow-mapping imports — review detected conflicts and decide per item before applying.
OAuth2 JWT client authentication: Outbound OAuth2 credentials support JWT client authentication via an explicit opt-in.
Global flow configuration page: Admin page for managing global flow configuration.
Service users — JWT credentials: JWT authentication credential management, with OAuth2 menu visibility gating.
Multi-select start-connector authentication: Select multiple authentication types for REST/SOAP start connectors.

Backend version surfaced: Health Check now reports the running backend version.
