# What's new in Sigma

> Sigma release notes for Apr 19, 2024: Cross-org template sharing, Snowflake key pair authentication and rotation, and more.

## Admin

### Cross-org template sharing

Send and accept workbook templates across different Sigma organizations.

With secure cross-org sharing, a receiving organization must choose its own data source to populate the shared template, ensuring no data from the sharing organization is disclosed.

For more information, see [Share and accept cross-org workbook templates](https://help.sigmacomputing.com/docs/share-and-accept-cross-org-workbook-templates).

### Snowflake key pair authentication and rotation

Create a Snowflake connection using the key pair authentication method, and protect your data with key rotation.

Key pair authentication offers enhanced security through the use of a private key (secured by Sigma) and a public key (shared with Snowflake) for encryption and decryption. By implementing periodic key rotation, you can further protect your data from threats of exposure and compromised keys.

For more information, see Sigma's [Snowflake Key-pair Authorization QuickStart](https://quickstarts.sigmacomputing.com/guide/security_snowflake_keypair_rotation).

### Scoped API keys

Define the scope of an API key to permit access to APIs only, embeds only, or both. This update provides more control over API privileges to ensure developers are granted relevant feature access.

For more information about client credentials, see [Generate API client credentials](https://help.sigmacomputing.com/docs/generate-api-client-credentials) and [Generate embed client](https://help.sigmacomputing.com/docs/generate-embed-client-credentials) credentials.

## APIs

### Embed signing packages

Use Sigma's sample code for signing embed URLs to reduce time to deploy embedded applications.

For sample code in Go, Python, Ruby, and JavaScript, see the [Embed Signing Packages Github](https://github.com/sigmacomputing/embed-signing-packages) repository.

## Workbook features

### Actions (GA)

Build workbook interactivity with [actions](https://help.sigmacomputing.com/docs/intro-to-actions) (now generally available) to create efficient workflows that produce quick and relevant data insights.

The GA release features additional effects in navigation, control value management, element modification, and data transfer. For more information, see the following documentation:

* [Create actions that navigate to destinations](https://help.sigmacomputing.com/docs/create-actions-that-navigate-to-destinations)
* [Create actions that manage control values](https://help.sigmacomputing.com/docs/create-actions-that-manage-control-values)
* [Create actions that modify or refresh elements](https://help.sigmacomputing.com/docs/create-actions-that-modify-or-refresh-elements)
* [Create actions that download and export](https://help.sigmacomputing.com/docs/create-actions-that-download-and-export-data)
