Global API Key Management Updates

This release adds global API key tag management, and preserves an appName display snapshot for historical app-level API keys. This update maintains backward compatibility for older API credentials, and simplifies administrative tasks by displaying the linked application context directly alongside each legacy key, making it easier to identify and manage keys tied to specific FastGPT applications.

Skill Publishing Pre-Extraction Workflow

When publishing a custom skill, the platform now pre-extracts the skill name and description to support streamlined content generation. This enhancement reduces redundant manual input during the publishing process, as core metadata fields are pre-populated automatically. Users can review and adjust the pre-extracted content before finalizing the skill publication.

Configuration & Marketplace Filter Improvements

Environment Variable Configuration

A new environment variable is available for self-hosted FastGPT deployments:

Environment VariableDefault ValuePurpose

Plugin & System Tool Filtering

The Plugin Marketplace now supports filtering plugins by official or community source origins, allowing users to narrow listings to preferred plugin types. Additionally, the system tool list includes filtering options for tool status and custom tags, streamlining discovery of relevant system tools for deployment and management.
