Aug 31, 2026: CoCo Desktop v1.21.2

CoCo Desktop v1.21.2 adds new ways to visualize query results and create automations, and fixes reliability problems in long-running sessions and at startup on managed machines:

  • Four new chart types: table and data_frame for tabular output, horizontal_bar_chart for ranked lists and long category names, and vega_lite_spec for charts the built-in types don’t cover, such as heatmaps, box plots, and layered or faceted charts.
  • Choose local or cloud when creating an automation: + New asks which kind of automation you want instead of following the active tab, and cloud automation titles are validated as you type.
  • Redesigned restricted session scope dialog: Read-only and named scopes share one selection flow that matches Snowsight, with role search matches highlighted and cancellable creation.
  • Fixed: memory leak in long chat sessions: Memory grew continuously and never recovered, reaching several gigabytes over multi-day uptime, because streaming tool calls retained their rendered output indefinitely.
  • Fixed: Desktop refusing to start under managed settings: A policy file saved as UTF-8 with a byte-order mark prevented startup. Genuinely malformed policy files still block startup by design.
  • Fixed: chat history lost on multi-root workspaces: Adding a second folder to a window no longer strands the chats belonging to the first.

This release also hides automation-generated sessions behind a Scheduled filter in the SESSIONS sidebar, targets the active connection for cortex automation commands run from chat, fixes a Snowflake catalog bug that could omit some of a schema’s tables, stops repeating MCP sign-in prompts, and keeps conversations attached to their Cortex thread after server-side summarization.
