# What's new in Sigma

> Sigma release notes for Mar 27, 2026: Support for Azure customer-owned cloud storage integration, null-safe join comparison operators, and more.

## Admin

### Support for Azure customer-owned cloud storage integration

Admins can now add an Azure Blob Storage integration to use customer-owned cloud storage with the following features:

* CSV upload
* File upload column in input tables
* Export to cloud storage

This adds Azure to the existing AWS and GCP storage options that give your organization control over where your files live, who can access them, how long they’re retained, and how they’re encrypted.

For more information, see [Configure storage integration using customer-owned bucket](https://help.sigmacomputing.com/docs/configure-storage-integration-using-customer-owned-bucket).

## Data modeling

### Null-safe join comparison operators

Joins support null-safe comparison operators, including null-safe equal to (**\<=>**) and null-safe not equal to (**\<!=>**).

Null-safe comparison operators return `True` or `False` instead of `Null` when comparing against `Null`. For example, `Null = 1` returns `Null`, while `Null <=> 1` returns `False`. For more information, see [Create and edit joins in data models and workbooks](https://help.sigmacomputing.com/docs/create-and-edit-joins-in-data-models-and-workbooks#create-a-join).

## Bug fixes

* After changing the Snowflake role in Sigma, write-back destinations available to a user did not update automatically.

* You can now change the data source of an element that uses a Snowflake semantic view as a source.

* Keyboard handling in the **Edit column descriptions** modal has been fixed to restore <kbd>space</kbd> key entry.
