| **Digital Twins:**<br />* Added `hierarchyPath` and `hierarchyMetadata` static attributes to the Digital Twins model. This lets Manufacturing Connect keep an instance's asset-hierarchy location in sync with Manufacturing Connect Edge.
* Removed the 2,000-item limit on the number of dynamic attributes that can be created on a single model. This allows for models that require a higher limit.
* Added `$EDGE_DT_MODEL_ID` and `$EDGE_DT_INSTANCE_ID` as available system variables for use in Digital Twins model and instance configuration. This supports tracking and analysis of Digital Twins data in external systems |

| **DeviceHub:**<br />* Fixed issue where the IEC102, Mitsubishi FX, Siemens TI505, and Fanuc drivers accepted certain multi-character address suffixes that produced incorrect register addressing. These suffixes are no longer supported.
* Fixed issue where the Beckhoff TwinCAT3 Ethernet Absolute (Gen1.3) and Beckhoff TwinCAT3 Ethernet Symbolic (Gen1.3) drivers returned a timestamp of `0` for failed tag reads. Tags now publish the current timestamp in this case. |
