We regularly add new topic areas or sets of metrics, sometimes called "compartments".
We'll let you know about these through our social media and emails.
You will see a set of topics under development at the bottom of the homepage.
Usually we release a new topic area in "alpha" before sharing it with everyone. This means a small number of users, such as our Model Ambassadors, get early access to test out the metrics, check the metadata is clear and that the data is showing as expected. This helps us iron out any teething problems before everyone gets access. If you have access to one of these topic areas, it'll be marked with an "alpha" label.
