Version 2026.254.5
Release Date: September 11, 2026
This release includes the customer-facing changes delivered since version 2026.204.8.
Availability: Features marked Cloud are available in cloud environments and are not included in the mindzieStudio Enterprise or mindzieDesktop packages. All other items apply where the corresponding workspace is enabled.
New Features
ML Studio - Now Generally Available
ML Studio is now generally available for guided predictive analysis. It helps you choose what to predict and when to make the prediction, trains candidate models, and explains the result before you apply it to your data.
- Honest evaluation - model quality is measured on held-out cases and compared with a simple "do nothing" baseline.
- Prediction timing guidance - a prediction-moment curve shows how accuracy changes as a case progresses and recommends the earliest useful prediction point.
- Feature controls - choose which attributes the model may use, including manual exclusions for information that would not be known at prediction time.
- Run history - revisit previous training runs and see which output columns each run added.
- Saved results - return to a saved report or share a direct link to it.
Object-Centric Event Logs
Upload OCEL 2.0 event logs and create analysis-ready event logs from their object types. The guided flow shows the available objects, lets you choose the case notion, and explains files it cannot safely import.
Generate BPMN Models from Event Logs (Cloud)
Process Intelligence can discover a BPMN model from an event log, evaluate alternative models, and generate a diagram with pools and lanes. The generated model can then be reviewed and refined in BPM Studio.
AI Process Intelligence Projects (Cloud)
The cloud service adds a dedicated AI Process Intelligence workspace for creating projects, uploading event logs, and moving from raw data into guided analysis.
Expanded BPMN Authoring
The BPMN editor now supports more BPMN 2.0 authoring scenarios, including message flows between pools, event data associations, call activities, groups, data object references, more event types, and direct flow renaming. Pool, lane, group, label, and boundary-event positioning have also been improved.
Improvements
Much Faster Conformance Analysis
Conformance analysis now reuses its prepared model instead of rebuilding it for every change. On a reference log with more than half a million events, an analysis that previously took five to six minutes now returns in seconds; small threshold adjustments return in under a second.
Reliable Working-Time Calculations
When a working calendar is enabled, case duration, activity duration, idle time, relative time, process-map durations, and duration calculators now consistently use working time. Logs without a working calendar are unchanged.
Faster Notebook Duplication
Duplicating, pasting, or importing a large notebook now opens the copy immediately and runs its blocks through the execution queue, keeping the browser responsive while processing continues.
Better Recovery After Connection Interruptions
mindzieStudio now recovers more cleanly after a temporary network interruption. Reconnect checks no longer compete with one another or reload a page after the connection has already recovered.
More Reliable AI Jobs
AI Job history and workspace state now survive navigation and refreshes more consistently. Archive uploads are supported, and uploading several files at once no longer causes files from the same batch to be reported as missing.
Data Designer Project Start
New Data Designer projects now open on the Data screen so you can begin adding and preparing data immediately.
Localization Quality
BPM Studio received a full localization pass across all supported interface languages, with additional Turkish corrections. Turkish characters are preserved in AI-generated BPMN models, and relative timestamps on the BPM Studio overview are localized.
Security and Administration
Protected Tenant Connection Strings
Per-tenant data-source connection strings are now encrypted with tenant-specific cryptographic keys, including key creation and rotation support.
Safer Sign-In and Validation Handling
Malformed sign-in requests now produce a controlled response instead of an application error. Administrators also have an emergency control for disabling SQL validation when diagnosing a compatibility problem.
Maximum Inactivity Timeout
The longest tenant inactivity timeout is now four hours, reduced from three days, to avoid keeping inactive server sessions open for extended periods.
Bug Fixes
| Task | Area | Description |
|---|---|---|
| 8811 | Pivot | A pivot whose saved configuration refers to a removed column no longer crashes |
| 8810 | Show Data | A saved sort that refers to a removed or empty column no longer leaves the analysis stuck in Pending Execution |
| 8750 | AI Jobs | Uploading several files in one batch no longer intermittently reports a file as not found |
| 8220 | ML Studio | Long milestone lists are no longer silently shortened when choosing where to make a prediction |
| 8187 | ML Studio | Multi-class predictions now write the correct class labels and include every trained class |
| 8219 | ML Studio | Training-run health checks and timeouts are more reliable |
| 8045, 8046 | Enrichments | Saved Activity Information and Set Attribute Value settings now reload correctly |
| 8971 | Working Calendar | Process maps, relative-time columns, and duration calculations now consistently respect the working calendar |
| 8967 | BPM Studio | Turkish characters are preserved when an AI Job creates a BPMN model |
| 8998 | BPM Studio | Relative timestamps on the overview page are localized |
| 8807 | BPM Studio | Imported BPMN diagrams no longer briefly render and then reset |
| 8227 | BPM Studio | Boundary events remain attached when their host activity is moved |
| 8256 | BPM Studio | Saved diagrams retain the expected editor changes |
| 8262 | BPM Studio | Event-based gateways are serialized correctly |
| 8267 | BPM Studio | Data associations connected to events are preserved correctly |
| 8064 | BPM Studio | Newly created BPMN elements receive valid identifiers |
| 8232, 8285 | BPM Studio | Pools are distributed and positioned more predictably |
| 8758, 8759 | BPMN Discovery | Generated models no longer contain unreachable elements in the affected Split Miner cases |
Upgrade Notes
- Existing multi-class ML Studio models trained before this release must be retrained before their next scoring run. The previous model format cannot be safely converted.
- Tenant inactivity settings above four hours are capped at four hours after the upgrade.
Known Issues
- If an investigation's hidden filter notebook contains a failing block, a duplicated, pasted, or imported notebook can remain in Pending Execution. Correct the failing filter before retrying the operation.
