Sep 8, 2026: CoCo Desktop v1.21.3¶

CoCo Desktop v1.21.3 isolates the Snowflake session that agent SQL runs in, adds full-text search across past sessions, and makes the redesigned dbt workspace the standard dbt experience:

• Isolated Snowflake sessions for agent SQL: SQL the agent runs uses a separate Snowflake session for each chat, so its role, temporary tables, and session variables stay apart from the SQL you run yourself. In Plan mode, that session is read-only automatically.
• Search your past sessions: Press Cmd/Ctrl+K in Agent Manager to search previous sessions by title, project, or conversation text, then reopen a result in its workspace.
• Choose how much reasoning a response needs: Set thinking effort from the model picker to favor a quicker answer or deeper reasoning, without changing models.
• The redesigned dbt workspace is now standard: Run dbt from the Project Action Bar and review command output, query results, compiled SQL, and lineage in the main workbench. You can retry failed models from Lineage and pick a Python interpreter per local project.
• Hardened PowerShell launching on Windows: Cortex Code starts PowerShell only from trusted system locations, so an untrusted workspace can’t substitute its own executable.
• Fixed: blank window after a catalog update: A startup regression could leave Desktop opening to an empty workbench.

This release also discovers App Runtime v2 projects that use app.yml in the Apps panel, adds a New SQL File action to the empty editor, keeps prompts sent during a tool run in their own conversation turn, and reduces memory growth from long-running terminals.
