+
+V2.0.8.1 introduces the **Object data type** to table models, significantly
enhances audit logging capabilities, optimizes the tree model’s **OPC UA
protocol**, adds **covariate-based forecasting** support in AINode, and enables
**concurrent inference** in AINode. Additionally, comprehensive improvements
have been made to database monitoring, performance, and stability. The detailed
release notes are as follows:
+
+- **Query Module**: Added a list view of available DataNode instances,
allowing users to [view each node's RPC address and
port](../User-Manual/Maintenance-commands_timecho.md#_1-7-viewing-available-nodes).
+- **Query Module**: Introduced a new system table for [statistical query
latency
analysis](../Reference/System-Tables_timecho.md#_2-20-queries-costs-histogram).
+- **Storage Module**: Added SQL support to retrieve the full definition
statements for
[tables](../Basic-Concept/Table-Management_timecho.md#_1-4-view-table-creation-statement)
and [views](../User-Manual/Tree-to-Table_timecho.md#_2-4-viewing-table-views).
+- **Storage Module**: Optimized the tree model’s [OPC UA
protocol](../../latest/API/Programming-OPC-UA_timecho.md).
+- **System Module**: Added support for the [Object data
type](../Background-knowledge/Data-Type_timecho.md) in table models.
+- **System Module**: Significantly enhanced and upgraded the [audit
log](../User-Manual/Audit-Log_timecho.md) functionality.
+- **System Module**: Added a new system table to monitor [DataNode connection
status](../Reference/System-Tables_timecho.md#_2-18-connections).
+- **AINode**: Integrated the built-in **Chronos-2** model, supporting
[covariate-based forecasting](../AI-capability/AINode_Upgrade_timecho.md).
+- **AINode**: Built-in models **Timer-XL** and **Sundial** now support
[concurrent inference](../AI-capability/AINode_Upgrade_timecho.md).
+- **Stream Processing Module**: When creating a full-data synchronization
pipe, it will be [automatically
split](../User-Manual/Data-Sync_timecho.md#_2-1-create-a-task) into two
independent pipes—one for real-time data and one for historical data—whose
remaining event counts can be monitored separately via the `SHOW PIPES`
statement.
+- **Others**: Fixed security vulnerabilities **CVE-2025-12183**,
**CVE-2025-66566**, and **CVE-2025-11226**.
