### Bug Fixes

For Cloud Robot - VM, it was possible to set a VM password that included the username. This is not allowed by Windows password requirements and therefore caused machine provisioning to fail. We have improved password validation when creating a VM to also check for this requirement.

### New Machine Sizes for Serverless Robots

We have added to the available machine sizes for running processes with UiPath Automation Cloud™ robots - Serverless.

#### Sizes and costs

Medium was the existing size, costing 4 RUs ([robot units](https://docs.uipath.com/overview/other/latest/overview/service-licensing#robot-units)) per minute of job execution. Three new sizes are now also available:

#### Choosing the machine size

Because each process has particular needs, you set the machine size in the configuration of a process.

For any cross-platform process, the **Cloud Robot - Serverless** list is available on the **Additional Settings** tab when [creating or editing a process](https://docs.uipath.com/orchestrator/automation-cloud/latest/user-guide/managing-processes).

The option is available for all cross-platform processes, which are candidates for being run using serverless robots, but the option has no effect unless it is executed by a serverless robot.

#### Automatic machine size selection

All your cross-platform processes have the **Cloud Robot - Serverless** option set to **Automatic**, which selects the appropriate machine size for the process.

The amount of robot units consumed to run the process is based on the machine size and the number of minutes it takes to run.

:::note
If you want to preserve your current RU consumption, you must manually change this setting to **Medium** for existing serverless processes. Medium was the only machine size used previously.
:::

For choosing the size, the criteria listed in the below table are evaluated in order. As soon as one criterion is satisfied, the corresponding machine size is chosen and the remaining criteria are not evaluated:

| Order | Criterion | Machine size |
| --- | --- | --- |
| 1 | Process depends on the UiPath Document Understanding activities | Large |
| 2 | Remote debugging job | Medium |
| 3 | Process depends on [UI Automation](https://docs.uipath.com/studio/docs/ui-automation) | Standard |
| 4 | Other unattended process | Small |

### Increased Concurrency Limit for Serverless

For Enterprise customers, we have increased the maximum number of serverless robot jobs that can run at the same time for one tenant from 20 to 50 concurrent jobs.
