All release notes

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.

The VALUES clause is now supported with dynamic table incremental refresh in INCREMENTAL, AUTO, and ADAPTIVE refresh modes. You can use VALUES in the FROM clause to supply a constant set of rows, for example as a small lookup table that you join to a base table.

Non-deterministic aggregate functions such as approx count distinct, approx percentile, and approx top k are now supported with dynamic table incremental refresh in INCREMENTAL, AUTO, and ADAPTIVE refresh modes. For incremental refresh, these functions are supported only in the SELECT clause. any value remains unsupported.

Snowflake Cortex AI Function Evaluation is now available in public preview, enabling customers to measure the output quality, cost, and token usage of custom AI Functions and Cortex AI calls against labeled datasets. Using the AI_FUNCTION_EVALUATION experiment type, customers can establish repeatable baselines and compare prompts, models, or function implementations using consistent datasets and evaluation criteria. Evaluations can be configured directly in SQL or through the guided Cortex AI Function Studio workflow.

Snowflake Cortex AI Function Optimization is now available in public preview, enabling customers to automatically search across prompts and models for improved implementations of custom AI Functions. Using the AI_FUNCTION_OPTIMIZATION experiment type, customers can evaluate multiple model candidates against a consistent dataset and metric, and compare their quality and estimated cost.

The Cortex Agents Compact API is now available in preview. Use the agent:compact endpoint to summarize a conversation and pass the compact representation to subsequent agent:run requests. Compacting conversation history reduces token consumption and helps conversations stay within the model context window.

With this release, we're pleased to announce the general availability of partition evolution for Snowflake-managed Iceberg tables. You can now change a table's partition specification after you create the table by adding, dropping, or replacing partition fields, without rewriting existing data.

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. Generation requires the Cortex Agent code execution tool on the associated agent. When the file is ready, you can view it inline in Snowflake CoWork.

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.

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.
