Every month PowerBI releases new features. Some of the features are in preview mode and unless you turn it on you don’t get to use the preview features. This post explains how to turn them on.
Firstly you need to have the latest version of PowerBI to get the latest features. You can download it here.
Next you go to File > Options and Settings > Options
Then select Preview Features and select the preview features you want to use.
You will then be prompted to restart PowerBI in order for the preview features to be available.
Once restarted you will have your preview features available and if they are visuals you will see them appear on the right hand pane. For example we can now see Python in the visualizations pane.
