Updated: November 27, 2019
The Azure Cosmos DB API for MongoDB now supports MongoDB wire protocol version 6 and server version 3.6. All new accounts provisioned using the Azure portal will have the option to provision with server version 3.6. Existing accounts will continue to be on v3.2 or v3.4 (based on their configuration) and will be fully supported. New capabilities include compound indexes, ChangeStream API support, creating unsharded collections with shared database throughput, and general availability for aggregation pipeline stages and operators.
