MongoDB version 3.4 has been available since December 2016.
We have enabled it by default for all new customers on EvenNode. As you're used to from the past, we provide free access to a MongoDB database for every application.
You can now enjoy new features such as new aggregation operators, expressions and views which are available in the latest version. To learn more on what's new in version 3.4, see full changelog in MongoDB documentation.
We will be happy to help you migrate from older MongoDB versions to the latest version. Please contact our support in case you're interested in the migration.
