New Feature Additions

This release delivers a suite of new capabilities across plugins, commercial edition tools, and core workflow functionality. The SearXNG search plugin is now natively supported, alongside dedicated webhook plugins for DingTalk and WeCom bots. The sandbox environment includes a new global createHmac encryption method for custom script use. Workflow editors can now right-click to collapse all nodes at once. For the suggested questions feature, users gain the ability to select a target model and configure custom prompts. Commercial edition subscribers receive scheduled sync support for API Datasets and link collections, plus DingTalk SSO login configuration and Lark/Yuque Dataset import, with linked tutorial documentation for the SSO and dataset import features.

Platform Behavior Improvements

Multiple core platform behaviors were refined to improve stability and reduce user-facing friction. The model selector interface has been updated for better usability. Server-side rendering (SSR) now pre-detects whether the client device is mobile or desktop, eliminating unnecessary page jitter during initial load. Variable initialization for both Workflow and Simple Mode was rewritten to remove listener-based initialization, which previously caused failures due to inconsistent render order. Workflow now automatically performs type conversion when receiving mismatched data types, preventing undefined values in downstream workflow steps.
