| --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Device Hub:**
* The following driver is available in this release:
- **SEW-EURODRIVE**
- SEW Driver Ethernet |
| **Digital Twins:**
* **Asset Hierarchy path and metadata: **Digital Twin instances managed by Litmus Edge Manager (LEM) store their hierarchy context in two static attributes. Both are read-only in LE and update only when LEM pushes a change:
- `hierarchyPath` contains the asset's full path withspaces and special characters replaced by underscores.
- `hierarchyMetadata` contains a set of key-value pairs, for example enterprise, region, site, plant, area, work center, and work unit.
* **Nested models: **A new dynamic Nested Model attribute type lets one Digital Twin instance reference another. For example, a production line instance can point to each of its machine instances. You pick the target model when you define the attribute and the specific instance when you configure it. LE resolves the topic for you. Transformations do not apply to this attribute type.
* **Static attributes in dynamic attributes publish: **When a dynamic attribute payload publishes on `digitaltwins...`, the message now includes the Instance's static attributes alongside the value in a `static_attributes`object. |
| **Analytics:**
* **Analytics AI Suite**
Manage all your AI resources on the new AI Suite page: models, instructions, skills, context files, tool definitions, MCP server registrations, memory, and agent files.
- Processors configuration allows user to select desired AI resour
- MCP and Tool management supports validation, test connection, tool list view.
- LE exports the resource tree as a ZIP file for backup or transfer to another instance, and imports a ZIP to restore it.
- LE stores, lists, and includes agent files in an export. Processor support for agents is planned for a future release
- Import and export for scaling and backup. |
| **Integration:**
* The following new connectors are available in this release:
- **Aveva**
- Aveva Data Hub Gen 2
- OSI PI Historian Gen 2
- **MaintainX**
- MaintainX API
- **Tiger Data**
- TimescaleDB
* SQL Gen 2 connectors now support JSONPath field mapping. Column mapping can read values from anywhere in a nested payload. This applies to the PostgreSQL, MySQL, and MS SQL connectors, so you no longer need to flatten nested telemetry upstream. Select **Enable JSONPath** on the connector configuration to switch mapping values from first-level payload keys to JSONPath expressions such as `$.factory.line.machine.sensors.temperature`. |
| **System:**
* Litmus Edge now includes Solution Templates, which capture the complete configuration of a Litmus Edge system as a JSON file that you can apply to other systems. You can parameterize a template, choose how it merges with existing configuration, and roll back to a snapshot taken before it was applied.
- **Parameters: **A template can contain parameters so one template serves many sites or devices without being edited. You enter the values when you apply the template. LE fills them into the settings and validates them before writes to the device.
- **Apply modes:** Three modes control what happens to configuration already on the device. **Reset & Apply** clears the existing configuration and replaces it entirely with the template. **Merge & Apply** combines the template with the current configuration. Items with new IDs are added, and items whose IDs already exist are overwritten after you confirm. **Apply** uses system logic, where each component decides individually whether to overwrite or keep an existing item.
- **Snapshots and rollback:** LE captures a configuration snapshot before a template is applied. You can browse snapshot history, capture a snapshot manually, and roll back to any earlier snapshot. A rollback is itself snapshotted, so it can be undone in turn. |

* With **Publish Additional Attributes **enabled, **DeviceHub Tag** payloads from the Modbus, OPC UA, and Siemens S7 drivers include `status`, `statusCode`, and `sourceTimestamp` keys.
* OPC UA Client Advanced supports an exclusion list for browsing: `i=2253 [Server]`, `i=86 [TypesFolder]`, and `i=87 [ViewsFolder]`.
* When tag creation exceeds the license limit, the error message now indicates `Failed to create Tag(s): Tag limit reached`.
* Improved bit encoding for the **Address** field when configuring a DeviceHub tag.
* Changing only the device name in a DeviceHub template and reapplying it creates a new device.
* The **Name** field warns you when you approach the character limit.
* Array and string tags in **DeviceHub** > **Data** display a tag's value rather than `0`.
* All Modbus drivers ship with revised default timeout and retry count values.
* AB Logix Ethernet supports array data types, and its unsigned integer types align with RSLogix types.
* AB Logix Ethernet batches string reads for faster performance.
* GE Ethernet Symbolic handles a missing optional global variables CSV file without failing.
* The GE Fanuc SNPX Serial driver name no longer includes the word "Driver".
* The EUROMAP 63 driver has a clearer overview and tool-tips for the session directory path.

* The REST Gen 2 connector accepts a method and API path for IT Hub requests.
* Throttling limit field names are now consistent across the REST API Gen 2 connector. |
| **System:**
* LDAP attribute names are no longer case-sensitive, so identity lookup succeeds regardless of the casing Active Directory returns. |
## Resolved issues

| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Dashboard:**
* Fixed issue where the dashboard displayed a GPU graph on hardware without a GPU. |
| **DeviceHub:**
* Fixed issue where the dashboard tag count doubled after an upgrade from 3.16.x to 4.0.x.
* Fixed issue where the Emerson DNP3 Ethernet with FB Extensions driver did not poll for history. The **Polling Interval** field was missing from the *Add* and *Edit* pages for History Alarm Event record tags in 4.0.x.
* Fixed string tag handling on the Mitsubishi FX3G Binary Ethernet driver. Multiple tags configured at the same address with different string lengths all received the same value.
* Fixed issue where a device using the ABB Robot Web Services driver connected and disconnected repeatedly.
* Fixed read failures when multiple devices share one serial connection through the Modbus Multi-Station RTU to TCP Converter combined with Modbus TCP.
* Fixed issue where every MID revision property on the Torque Tool Open Protocol Ethernet driver rejected any value except `1` and reported `Maximum allowed value is 0`. |
| **Digital Twins:**
* Fixed issue where the model image preview did not reset after clicking **Reload**. |
| **Analytics:**
* Fixed issue where creating a flow failed with a `validation: processor with name "Flow - [n]"` already exists message, because a uniqueness check rejected the processor names that flows share by design.
* Fixed issue where the Playground reported `inputProcessors is not defined` for a JavaScript processor.
* Fixed issue where no error displayed when creating a DataHub Subscribe processor without a topic.
* Fixed issue where duplicate processor names were allowed.
* Fixed issue where groups could be created with an empty name.
* Fixed issue where leaving a newly created instance and returning to it opened a different instance instead. |
| **Applications:**
* Fixed issue where a Docker Compose release with an external network name override did not attach to the resolved network. Variable placeholders in external network names are now resolved at launch and in the delete protection list. |
| **Integration:**
* Fixed issue where an external InfluxDB connection passed its connection test but did not receive data. Logs reported `not found: bucket "tsdata" not found` even when the database had been created manually.
* Fixed issue where the Databricks Zerobus Ingest connector reported a `Connected` status despite incorrect configuration settings.
* Fixed issue where the AWS IoT SiteWise connector forwarded messages with a `null` value. Those messages are now dropped.
* Fixed issue where trailing spaces were accepted in a connector name uploaded through a template, which produced duplicate connector names.
* Fixed issue where connector templates omitted the **Enable Logging** field.
* Fixed issue where identical templates were marked as updated instead of skipped on upload.
* Fixed issue where the **Username** and **Password** fields on the MongoDB v4 and later Gen 2 connectors were not marked as required in the UI.
* Fixed issue where the *Drop Count* chart in the connector dashboard changed color on page refresh.
* Fixed issue where long connector logos overlapped the enable button in cards on the *Integration* page. |
| **OPC UA:**
* Fixed issue where nested event properties in OPC UA Client Advanced returned null values. Values from OPC UA server are now properly published in Litmus Edge.
* Fixed issue where the Litmus Edge OPC UA Server intermittently refused new connections while still reporting an `OK` status. The receive queue on port `4840` was not drained and stale connections accumulated in `CLOSE_WAIT`, so `DiscoveryClient.GetEndpoints` returned `BadRequestTimeout`. Restarting the server cleared the condition.
* Fixed issue where applying a template cleared a newly added hierarchy instead of preserving the existing hierarchy.
* Fixed issue where the tree hierarchy did not update until you navigated away and back again. This occurred when adding a tag to an empty OPC UA tree for the first time. |
| **System:**
* Fixed issue where LE lost a static route if the connection was manually disconnected.
* Fixed Edge Cascading and NATS server restart failure in Litmus Edge Docker 4.0.12 and 4.0.13. |
