Technical & Minor Version Release Notes

A comprehensive list of all technical information regarding new releases. Includes warnings, which usually have implications on existing models and settings, as well as general technical information.

‌

7.1.0

Major

API Changes

No API Changes

Warnings

parameterEffectProxy Node Property Removed from ModelDSL (MEDIUM)
The node property parameterEffectProxy no longer exists in ModelDSL. Uploading a ModelDSL containing this property will result in a crash. If your ModelDSL includes parameterEffectProxy, it can be safely deleted as its functionality was removed in a previous version.
ROLLUP Function No Longer Accepts Dimension Names as Input Parameters (HIGH)
The ROLLUP function signature now requires Level names only and no longer accepts Dimension names. Example — Before: ROLLUP("Node 1", "Time", "Year"), After: ROLLUP("Node 1", "Year"). The release will automatically migrate all existing ROLLUP usages to the new syntax. Note: including a Dimension name will now cause the function to fail. Edge cases requiring manual updates after migration: ROLLUP calls inside comments will not be updated; if ROLLUP inputs span multiple lines with a comment on the Dimension line, the comment will shift up one line after migration.
Removal of Not Supported Endpoints (LOW)
The endpoints POST /v1/perspectives and DELETE /v1/perspectives have been removed. These endpoints were never officially supported. To modify the perspectives of a perspective chart, use PUT /simulationCharts/{id}/updatePerspectives instead.

‌

7.0.1

LTS - Hotfix

API Changes

Removal of Chart Thumbnail Endpoints (LOW)
The endpoints for chart thumbnails (GET /simulationCharts/{id}/thumbnail, POST /simulationCharts/{id}/thumbnail, DELETE /simulationCharts/{id}/thumbnail) have been removed as they were not in use. Image charts and perspectives are unaffected.

Warnings

No Warnings

7.0.0

LTS

API Changes

Removal of Global Parameter Effects Endpoints (LOW)
The REST endpoint GET /simulationWorkspaces/{id}/parameterEffects and WebSocket endpoint /simulation/parameterEffects have been removed. These endpoints returned global parameter effects per workspace.
Removal of Legacy Snapshot Workspace Endpoint (LOW)
The endpoint POST /simulationWorkspaces/{workspaceId}/snapshot has been removed.

Warnings

Presentation Mode Disabled by Default (HIGH)
Presentations (Workspace Snapshots) are now disabled by default via the new configuration flag featureFlags.presentationModeEnabled. On fresh deployments, this flag is set to false. On existing instances, it is set to true only if snapshots exist in the database. The flag cannot be modified via the Settings page; it requires a direct API call or database access. When false, creating new snapshots in the Scenario Manager is disabled and Presentation management UI pages are inaccessible.
Operation per Scenario Renamed to Operation per Baseline (MEDIUM)
The feature previously known as “Operation per Scenario” has been renamed to “Operation per Baseline” across the UI and ModelDSL. Any ModelDSL using the old property name will need to be updated to reflect this rename.
Scenarios Renamed to Baselines (MEDIUM)
Scenarios have been renamed to Baselines throughout the application. This affects UI labels, API parameter names, and ModelDSL properties. Review any integrations or scripts that reference “scenario” terminology.
