Improvements#

AI#

  • Maximum Questions and Maximum Concurrent Questions settings in the Batch Q&A widget, with rolling-window answer generation that immediately starts the next queued question when a slot frees up, and a Queued state for questions awaiting their turn.

  • frontend.sqgpt.max-upload-files project configuration to set the maximum number of files a user can attach to the Squirro Chat widget upload.

  • Open References in a New Tab option in the Chat widget, which opens a chat answer reference in the Document Details in a new browser tab instead of the in-app item detail modal.

  • File type check when uploading files for Chat with Document.

Bug Fixes#

  • Ingestion pipeline failing validation in the Rhein data loader plugin when the lastModifiedDate or createdDate facet was mapped to a Squirro system field, blocking item removal across all batch types.

  • Non-extractable file types not handled in the SharePoint data loader plugin.

  • “No available connectors” message when creating a new data source in a new containerized deployment.

  • topic service failing to start in fully containerized deployments with limited or no outbound internet access.

Breaking Change#

Removal of the Squirro Cluster Service (sqclusterd) and all related logic, configuration (cluster.ini, the endpoint_discovery and db_endpoint_discovery settings), monitoring integration, and packaging.

Multi-node deployments that relied on the cluster service for MySQL and Redis endpoint discovery and replication management are no longer supported as of Squirro 3.16.2.
