> May 2022 release notes for Robot in Automation Cloud.

## May 11, 2022

### Renaming

What was previously called **Automation Cloud robots** (ACR) is now renamed to **UiPath Automation Cloud**™ Robots - VM, or **Cloud Robots - VM** for short.

This is because we now offer two types of Automation Cloud robots: **Cloud Robots - VM** and **Cloud Robots - Serverless** (UiPath Automation Cloud™ Robots - Serverless).

### Cloud Robots - VM and Cloud Robots - Serverless are now GA

The **UiPath Automation Cloud**™ Robots - VM and **UiPath Automation Cloud**™ Robots - Serverless features are now general availability (GA) features.

In addition, **Cloud Robots - Serverless** is now also available to Enterprise and Enterprise Trial customers.

[Cloud Robots - VM](https://docs.uipath.com/robot/automation-cloud/latest/user-guide/about-automation-cloud-robots-vm) and [Cloud Robots - Serverless](https://docs.uipath.com/robot/automation-cloud/latest/user-guide/automation-cloud-robots-serverless)

### Maintenance window settings

As part of configuring the **Cloud Robots - VM** machine template, you can now set an automatic maintenance window for all machines created from the template. This allows you to safely push and install software upgrades or to perform other maintenance tasks on all machines that belong to the template.

### Licensing changes

Based on feedback and usage patterns, we have changed the licensing type used for cloud robots (both VM and Serverless).

### Robot units

Instead of the **Automation Cloud Robot** license, which was a runtime license, we are now introducing **Robot units** (RUs) as a service consumption unit license. This license type allows for a predefined amount of usage per month and the license units are consumed as you use the feature.

To learn more about this license type, see [Robot units](https://docs.uipath.com/overview/other/latest/overview/service-licensing#robot-units).

### Automation Cloud Robot license

Enterprise customers received one **Automation Cloud Robot** license when we released Cloud Robots - VM as a preview feature - at the time known as Automation Cloud Robots.

The Automation Cloud Robot license will continue to be available until 30 May 2022, after which it will be removed. Unlicensed machines will be deleted after another 60 days if they remain unlicensed.

If you are interested in continuing to use Cloud Robots - VM, you will need to purchase robot units for your organization. For assistance, [contact Sales](https://www.uipath.com/company/contact-us).
