About Technical Preview Features

In the Beta2 version, some experimental features are being pushed to the system repository in a technical preview state. The completeness of these technical preview features is far from being ready for production, so they are not provided by default. Users need to perform some manual configurations to experience them.

To simplify the process of trying out these technical preview features, we have provided additional extensions for users who wish to experience them. These extensions allow you to get an overview of all the current technical preview features.

To install this extension manually (please ensure you have completed the system update for Beta2):

sudo apt install dcc-insider-plugin

Once the installation is complete, you will find a new menu item under the system's control center, under "Updates," and then "Technical Preview". Within this menu, you will see a list of all the technical preview components that you can enable or disable through a graphical interface.

Please note: All technical preview features are actively under development, and these components may be unstable, both in terms of their interface and functionality, and are not in their final completed state. We are offering this technical preview to provide users with insights into our technological direction and progress. We encourage those interested in the related technologies to discuss them within the developer community. However, there is no need to provide feedback in the form of issues at this time.
