With release 22.2 we decided to change the way in which we present and search for content in our knowledge base. For the sake of a smooth overlap, the new KB includes the documentation for release 22.1.
Users wishing to view content pertaining to releases 21.1 and prior can do so via the knowledge base.
While the Old KB is presented in our new KB aesthetic, the documentation displayed in it is structured differently. The product documentation and its respective versions as elements of the navigation tree. This means that there is no faceted search or version dropdown available in the Old KB. These new search features are only available in the new KB.
