| 2 | Full Run Details Panel | Corrected incorrect Markdown parsing of plain-text tool responses that caused unintended formatting issues |
| 3 | Embedding Model Management | Fixed scenario where switching embedding models triggered reindexing but did not rebuild vectors for existing dataset data |
| 4 | MinIO Storage Operations | Fixed bulk deletion failures using prefix paths caused by XML entity expansion limits, and added request timeout protection for storage operations |
| 5 | Enterprise Verification Flow | Fixed bank account validation errors during enterprise verification processes |
| 6 | Agent V2 Tool Configuration | Resolved inconsistencies between the displayed Agent V2 tool list and its associated prompt text |
| 7 | Deployment Configuration Files | Fixed syntax errors in deployment .yaml script files |
Post-Upgrade Validation Checklist
To confirm all fixes are successfully applied after upgrading to FastGPT 4.15.4, follow these sequential steps:
- Initiate a chat session with a tool-integrated assistant, and verify no system tool error messages appear during streaming response delivery.
- Execute a complete workflow run, then access the full run details panel to confirm plain-text tool responses render without unintended formatting issues.
- Navigate to the dataset model settings, switch the active embedding model, and confirm the system automatically rebuilds existing dataset vectors without requiring manual reindexing.
- Target a stored dataset with a defined storage prefix, initiate a bulk deletion operation, and confirm the task completes without failure.
- Complete a test enterprise verification flow, and confirm bank account validation processes complete successfully.
- Configure an Agent V2 assistant, review the configured tool list and associated prompt text to confirm alignment between both fields.
- Validate your deployment
.yamlscript files using your standard infrastructure orchestration tools to confirm no syntax errors are resolved.
