Version 1.16.0

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

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. Disabled by default (opt-in).
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.
Authenticated identity in flow logs: Flow logs now record which authenticated user triggered the message.

Self-starting and asynchronous flow errors are now reported on the monitoring screens.
Mail receivers can now connect to servers that require no authentication.
Flow Simulation reliability improvements, including role-based access control and accurate per-step results.

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 and OAuth2 support reflected across the server.
Authenticated identity in logs and export: The authenticated user is included in logs and CSV export.

Flow import now handles name collisions gracefully by renaming on conflict.
API Management disabled state is handled correctly — no unnecessary gateway refresh while the feature is off.
Flow Simulation reliability fixes, including history ownership filtering and identity forwarding.

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.
FTP/SFTP additional parameters: FTP and SFTP receiver node panels now support additional connection parameters.
Global flow configuration page: Admin page for managing global flow configuration.
RFC destinations — refresh metadata: New refresh-metadata action in the row menu.
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.
Authenticated identity in monitoring: Message monitoring detail now shows the authenticated user.
Splitter connection rules: Splitter outgoing connections are restricted to Direct and End nodes.

Fixed AI Monitoring report download.
Flow Simulation UI fixes: panel visibility, per-flow input reset, no stale results, dark-mode results, and correct drawer layering above the designer dialog.

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

This is a Release Candidate (pre-release); after validation the final 1.16.0 release will be published. Previous: 1.14.0
