All release notes

• Schema-level data metric functions: exclude transient tables

Observability for Cortex Agents in a Snowflake Native App now includes the following capabilities:

• Intellectual property protection during event logging: When an app initiates a run through the REST agent:run API or SQL DATA_AGENT_RUN, Snowflake redacts orchestrator-authored content before writing the consumer event-table record.
• Event sharing for agent telemetry: When a consumer enables event sharing, the provider receives agent telemetry at the AI_METADATA sharing level by default or at the AI_CONTENT sharing level after the consumer approves the SHARE_AI_OBSERVABILITY_CONTENT app specification.

The following updates are now available in Snowflake Data Clean Rooms:

• Faster setup and iteration for same-organization collaborations: For collaborations created after this update, if every collaborator belongs to the same organization, Snowflake skips the automated security scan, so the collaboration and its updates become available sooner. Existing collaborations aren't affected, and cross-organization collaborations always have to pass the scan. To run the scan for same-organization collaborations, set the new optional distribution: external field in the collaboration's specification. For more information, see iterating quickly in a same-organization collaboration.
• Clean room creation disabled in the legacy web application: As part of the ongoing deprecation of the legacy Data Clean Rooms web application, you can no longer create new clean rooms through the legacy web interface. Existing legacy clean rooms aren't affected, and the clean room list page now shows a banner with the remaining retirement dates. Use the Collaboration API and the Snowsight Data Clean Rooms UI to create new clean rooms moving forward. For the full timeline and migration guidance, see the end-of-life page for legacy Provider and Consumer clean rooms.
• General performance improvements and bug fixes.

Remote app operations for Snowflake Native Apps are now generally available.

CoCo Desktop v1.21.6 refines everyday chat controls and shores up connectivity:

• Grouped model picker with thinking effort: The composer model picker is reorganized, and the thinking effort control now lives inside it as a nested row.

With this release, Inline Stored Procedures for hybrid tables are generally available. Inline Stored Procedures are a type of Snowflake stored procedure designed for operational workloads on hybrid tables. The entire procedure body runs as a single atomic unit pushed directly to the query processing layer, which reduces per-statement overhead and delivers significantly lower latency for OLTP-style workloads.

Code Bundles let you package non-SQL code, like Python, and run it directly on Snowflake compute with a single command, without wrapping it in a stored procedure. This release expands Code Bundles with two new ways to run, in preview:

• Warehouse execution: run Python Code Bundles directly on warehouse compute by setting compute_type: warehouse, in addition to compute pools.
• Spark jobs: submit Spark applications (Scala, Java, or Python) as batch jobs on Snowflake compute by setting type: spark. Spark support is built on Snowpark Connect, so you can run existing Spark code on Snowflake without re-platforming it.

The following updates are now available in Snowflake Data Clean Rooms:

• Data Clean Rooms UI in Snowsight - Generally Available: Managing collaborations in the Snowsight UI is now generally available. You can browse, create, review, join, and manage collaborations, share templates and data offerings, and run analysis, directly in the UI. This release also includes the following improvements:
• New Activity tab: A new Activity tab gives you an audit trail of the analysis template runs in a collaboration. You can filter and sort the runs, and open any run to see its inputs, parameters, and outcome. What you see depends on what your account contributed to the collaboration. For more information, see activity history.
• Get started guide: A guided walkthrough of setting up a test collaboration and running your first analysis is now available from Get started at the top right of the tabs.

With this release, hybrid tables support CHECK constraints. Previously, CHECK constraints were limited to standard tables and Snowflake-managed Iceberg tables, so a hybrid table workload had to enforce value-level rules in application code.

HTML generation is now available in preview as part of document generation in Snowflake CoWork. You can ask Snowflake CoWork to generate an HTML file from your analysis, the same way you generate a PDF or PowerPoint.

CoCo Desktop v1.21.5 is a small quality release on top of v1.21.4, focused on error messages that tell you what to do next:

• Recovery guidance when a local dbt executable is missing: A Run or Build that can't find dbt now explains how to recover in the Current Project Output panel, instead of showing only a failed marker.
• Clearer errors when a shared skill or plugin can't be installed: A missing or inaccessible catalog object now points you to the current account and role.
• More accurate memory guidance for the agent: The agent's instructions distinguish memory already supplied in context from records that need an explicit cortex memory recall, and set a tighter bar for saving durable memories.

...

Read more

The following Cortex Agents object enhancements are now generally available:

• Temporary agents: Create session-scoped agents for testing, one-off workflows, and ephemeral pipelines by using CREATE TEMPORARY AGENT or CREATE TEMP AGENT.
• Secure agents: Prevent roles that can invoke or modify an agent, but don't have its owner role activated, from retrieving the agent specification through metadata surfaces.
• COPY GRANTS support: Preserve explicit privileges, except OWNERSHIP, when replacing an agent with CREATE OR REPLACE AGENT ... COPY GRANTS.

The following updates are now available in Snowflake Data Clean Rooms:

• Legacy identity connectors removed from the web application: As part of the ongoing deprecation of the legacy Data Clean Rooms web application, the Acxiom - Real ID, Acxiom Real ID Transcoding, LiveRamp, Merkury, Experian, and The Trade Desk UID 2.0 connectors have been removed from the provider and consumer web interface. This change does not delete existing connector configurations.
• Legacy activation connectors removed from the web application: As part of the ongoing deprecation of the legacy Data Clean Rooms web application, the Google Display & Video 360, Google Display & Video 360 - PAIR, LiveRamp, The Trade Desk - UID 2.0, The Trade Desk - CRM, and Yahoo DSP connectors have been removed from the provider and consumer web interface. This change does not delete existing connector configurations.
• General performance improvements and bug fixes.

External secret providers are now in preview. If your organization already keeps API keys, database passwords, and similar values in AWS Secrets Manager, Azure Key Vault, or Google Cloud Secret Manager, Snowflake can read those values when a query needs them, so you don't have to maintain a second copy in a Snowflake secret.

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.

With this release, you can add and drop UNIQUE and FOREIGN KEY constraints on an existing hybrid table by using alter table. Previously, you had to define these constraints when you created the table, so adding a foreign key to a table that was already serving a workload meant recreating and reloading the table.

You can now use data lineage to see which data a Cortex Agent can reach through the tools declared in its specification. A semantic view that a Cortex Analyst tool references, and a Cortex Search service that a Cortex Search tool references, both appear upstream of the agent. Because a semantic view is itself downstream of the tables it references, you can trace the whole path from a table, through the semantic view, to the agent that consumes it.
