2026.05

This release rebuilds the Workflows page, redesigns Administration and audit logs, adds OAuth 2.0 access for external applications, brings Mind duplication and private conversations, introduces an S3 connector, expands Observability, and adds container controls to the DataMind Installer.

Workflows

• Rebuilt Workflows page: Workflows, jobs, and nodes now share one redesigned workspace with metadata cards, a filter toolbar, and per-item actions.
• Clearer job and node tables: Failed nodes show a full error stack, each workflow carries its own icon, and run and schedule actions sit directly in the list.

Minds

• Duplicate a Mind: Copy a Mind together with all of its training cards in one action.
• Mind Hub explorer: Browse, search, and filter training cards in a side explorer, and disable a card without deleting it.
• Train from chat: A "Train" action on a chat response turns that response into a training card.
• Private conversations: Mark a conversation as private; private chats stay out of shared views and are covered by their own permission.

Administration

• Redesigned Administration: Users and roles now share one table and detail layout, with role filtering and a batch register flow.
• Per-user ClickHouse memory limit: Set and save a memory limit per user from the user details page.
• Permissions audit report: Export the full permissions audit to Excel; downloading audit records has its own permission.

Security & Sign-In

• OAuth 2.0 access: External applications can connect through a standards-based OAuth 2.0 authorization flow.

Audit Logs

• Redesigned audit logs: A new layout with period and status filters, pagination, and per-column filters, plus server-side download of audit and query logs.

Observability

• Query management rework: A new layout, an inline SQL view, line breaks kept in the query log, and a slow-responses chart.
• Query insights: New views for failed, repeated, and high-maintenance queries, with server-side filtering.
• Rebuilt System Overview: Filters, keyboard shortcuts, and an incident side panel.

Lake & Connectors

• S3 connector: Connect an S3 bucket as a data source, with connection testing, structure reading, and automatic table generation. See Connect your data source.
• MSSQL trust server certificate: A new toggle for SQL Server connections that use self-signed certificates.
• MongoDB TLS: MongoDB connections now accept TLS/SSL certificates.
• Rebuilt Lake sidebar: A new source menu with multi-select actions, plus node deletion.
• Custom connector chats: Undo and redo steps while building a custom connector with AI.

DataMind Installer

• Container controls: Restart, stop, and kill deployment containers, with live status for each one. See Service status.
• Streaming job logs: Follow a deployment job with live job logs and cleaner container logs. See Health, monitoring and logs.
• Clearer errors: Deployment operations return structured errors with more useful messages. See Troubleshooting.
• Parallel downloads: The Installer downloads images in parallel.
