Missing features

• Some of the updates with Transforms (such as Maximum and Minimum)
• Multiplexing listeners in a single stream (used by frontend Firestore SDK)
• Nearest neighbors search
• Some field filters (such as ArrayContainsAny and NotIn)
• Some API's that are not used by NodeJS SDK anymore (such as CreateDocument and Updatedocument)
• Explain options
• and many more... search for unimplemented to get the idea

And also missing a lot of documentation.
