Back to changelog

Highlights

Added Database Connectors in the conversational prompt box with connection test/save flow and active-connection chip
Added multi-engine connector support (PostgreSQL, MS SQL Server, Databricks, Snowflake, MySQL, Supabase) with package checks/install flow and clearer connector forms
Added SQL execution integration with notebook variables (`df_sql_n`) and direct SQL output rendering in chat
Added schema and table context controls, including table scan, table selection for LLM context, and Database Tables visibility in Data Awareness
Improved workflow execution reliability and UX, including prompt sequencing, duplicate-send prevention, progress behavior, and Run all/Stop all controls

Added

  • Added Database Connectors directly in the conversational prompt box, including connection test/save flow and an active-connection chip.
  • Added multi-engine connector support for PostgreSQL, MS SQL Server, Databricks, Snowflake, MySQL, and Supabase.
  • Added package checks and install flow for connector dependencies, with clearer connector forms.
  • Added SQL execution integration in conversational flows. SQL blocks are executed, results are materialized into notebook variables as df_sql_n, and SQL output is rendered directly in chat.
  • Added schema and table context controls, including table scan, table selection for LLM context, and Database Tables visibility in Data Awareness.
  • Added prompt-area quality-of-life updates, including working-directory chip/display improvements.

Improved

  • Improved workflow execution reliability with strict prompt sequencing, improved completion handling for both code and no-code paths, duplicate-send prevention, and more stable run progress behavior.
  • Improved workflow UX with Run all / Stop all controls, options menu updates, responsive narrow-layout rows (progress and actions on the second line), and sidebar polish.
  • Improved toast behavior to reduce repeated noise during conversational workflows.

Fixed

  • Fixed classic sidebar stability issues by hardening channel identity handling and reducing duplicate stream rendering.
