+V2.0.8.1 introduces the new **Object data type** to table models, enhances **AINode** with covariate-based forecasting and concurrent inference capabilities, optimizes audit logging and full-data synchronization features, and delivers comprehensive improvements to database monitoring, performance, and stability. Detailed release notes are as follows:
+
+* **Storage Module**: Added support for the [Object data type](../Background-knowledge/Data-Type_timecho.md) in table models.
+* **Query Module**: Introduced several new system tables:
+  - [CONNECTIONS](../Reference/System-Tables_timecho.md#_2-18-connections-table) (real-time connection tracking),
+  - [CURRENT_QUERIES](../Reference/System-Tables_timecho.md#_2-19-current-queries-table) (active query monitoring),
+  - [QUERIES_COSTS_HISTOGRAM](../Reference/System-Tables_timecho.md#_2-20-queries-costs-histogram-table) (query duration distribution).
+* **System Module**: Enhanced the [audit log](../User-Manual/Audit-Log_timecho.md) functionality.
+* **AI Module**: Added support for [covariate-based forecasting and concurrent inference](../AI-capability/AINode_Upgrade_timecho.md).
+* **Other Modules**: Upgraded the [OPC UA protocol](../../latest/API/Programming-OPC-UA_timecho.md) to support data push.
