Full Release Notes

##  Highlights of This Release

**1. Batch Execution Support and the Introduction of the Laboratory Interface**
A new **batch run** capability has been added, enabling efficient batch-level execution of tasks and substantially improving scalability for large-scale experiments. Alongside this feature, a **Laboratory interface** is introduced to provide a more intuitive environment for running batch experiments, comparing configurations, and managing experimental results in research-oriented workflows.

**2. Interface Upgrade: Legacy Chat Interface Support and Enhanced Function Calling Stability**
Support for the **legacy Chat interface** has been added to maintain alignment with earlier OpenAI API semantics. Alongside this, multiple function calling issues—such as API call failures, redundant return values, and JSON/JSONL parsing errors—have been fixed, enhancing stability in complex and multi-turn chat scenarios.
 
**3. Other Engineering and Documentation Improvements**
Additional updates focus on overall system stability and usability, including:

* Fixes for dynamic configuration issues, parallel image generation errors, and legacy branch linking problems;
* Updates to example configurations (e.g., `GameDev_v1.yaml`) to remain consistent with current functionality;
* Expanded documentation on context window usage and explicit warnings for `--reload` in file output tasks;
* Improved troubleshooting guidance in the README for common frontend–backend disconnection issues.
