## V2.0.5

> Release Date: 2025.08.21

V2.0.5, as the official release of the Dual-Model Tree-Table system, primarily introduces the tree-to-table view, window functions for the table model, the aggregate function approx_most_frequent, and supports LEFT & RIGHT JOIN as well as ASOF LEFT JOIN. The AINode now includes two new built-in models, Timer-XL and Timer-Sundial, and supports inference capabilities for both tree and table models. Additionally, this version brings comprehensive improvements to database monitoring, performance, and stability. The specific updates are as follows:

* **Query Module**: Supports manual creation of tree-to-table views
* **Query Module**: Adds window functions for the table model
* **Query Module**: Adds the aggregate function approx_most_frequent for the table model
* **Query Module**: Extends JOIN functionality for the table model, supporting LEFT & RIGHT JOIN and ASOF LEFT JOIN
* **Query Module**: The table model now supports row pattern recognition, enabling the capture of continuous data for analysis and computation
* **Storage Module**: Adds multiple system tables for the table model, such as VIEWS (table view information) and MODELS (model information)
* **AI Module**: AINode adds two new built-in models, Timer-XL and Timer-Sundial
* **AI Module**: AINode supports inference functions for both tree and table models

## V2.0.4

> Release Time: 2025.07.09
> Release Date: 2025.07.09

V2.0.4 serves as the official release of the dual-model system for tree and table structures. The table model primarily introduces user-defined table functions (UDTF) and multiple built-in table functions, adds the aggregate function approx_count_distinct, and supports ASOF INNER JOIN for time columns. Additionally, script tools have been categorized and reorganized, with Windows-specific scripts separated. The release also includes comprehensive improvements in database monitoring, performance, and stability. The detailed updates are as follows:
