DocumentDB vs Cosmos DB - are both the same?

I used DocumentDB for the product, and now I hear that there is no DocumentDB! This is the new Cosmos database that Microsoft is creating, which is a superset of DocumentDB. I'm really confused now.

Is it just the name they changed, or are there many more changes? Can someone shed some light on this?

Azure Cosmos DB began at the end of 2010 to address the virus-related issues that are affecting large-scale applications inside Microsoft. Since creating globally distributed applications is not a problem unique to Microsoft only, we have made the service available to all Azure developers in the form of Azure DocumentDB. Azure Cosmos DB is the next big step in the evolution of DocumentDB, and now we make it available to you. As part of this release of Azure Cosmos DB, DocumentDB clients (with their data) automatically become Azure Cosmos DB clients. The transition is seamless and they now have access to a wider range of new features offered by Azure Cosmos DB.

Azure Cosmos DB is a superset of DocumentDB.
