### What's new

#### Python version deprecations

Python36 is currently officially out of support from **Python**, with Python37 following in the next six months. To avoid any interruptions in your **AI Center** experience, we have new versions of the models and we strongly encourage you to use them. To avoid any issues, we recommend moving your own packages from Python36 to Python 38.

We recommend that you regularly check the [deprecation timeline](https://docs.uipath.com/overview/other/latest/overview/deprecation-timeline) for any updates regarding features that will be deprecated and removed.For more information on the status of Python versions, check the [official page](https://endoflife.date/python).

#### New Semantic Similarity version

A new version is available for the **Semantic Similarity** model. This version brings several minor improvements and bug fixes.

#### Notification Service integration

We are happy to announce the new notifications feature within **Automation Cloud** portal for **AI Center** events. You can now receive built-in notifications through two channels, in-app and email to notify them with the most relevant events:

* **Dataset**
  + Download readiness
* **ML Package** validation
* **ML Pipelines** status change
* **ML Skill** status change

You can manage your own preferences for opting-in or opting-out of these notifications from the user profile.

#### Python39

We are excited to announce that you can now use Python39 models.

### Improvements

* This release brings improvements to cluster and infrastructure stability.
* For improved usability, the **Waiting for licenses** error message due to licenses not available is updated to a more clear message. A failed reason for the pipeline is now added in the table. The failed reason is displayed in the interface if the pipeline failed.
* For improved usability, the **Downloading** message when a dataset is ready for download is updated to a more clear message. The updated message is now **Packaging**.

### Bug fixes
