# What's new in Sigma

> Sigma release notes for Oct 4, 2024: New API rate limit, create time series forecasts, and more.

## API

### New API rate limit

The `v2/auth/token` endpoint is now rate limited to one request per second.

See [Get started with the Sigma REST API](/reference/get-started-sigma-api#api-limits).

## Functions and calculations

### Create time series forecasts (Beta)

In a Sigma workbook, you can use historical time series data to predict and visualize future values and trends. This feature enables Sigma users to leverage Snowflake's [forecasting ML function](https://docs.snowflake.com/en/user-guide/ml-functions/forecasting) without requiring prior SQL knowledge.

See [Create time series forecasts (Beta)](https://help.sigmacomputing.com/docs/create-time-series-forecasts).

## Bug fixes

* When a workbook action is configured to set a control value on click in a visualization element, clicking on the white space outside the chart now clears the control value as expected.
* Workbook actions triggered from interactions with tables which have columns that either do not have a type or an error type now run as expected.
* When users send a request to their admins for a tag to be applied to their workbook, the resulting email notifications now use custom branding settings configured for the organization.
