# RabbitMQ version distribution on CloudAMQP

By Lovisa Johansson. Published 3 December 2018.

43% of all clusters at CloudAMQP are now running RabbitMQ 3.7!

..and some users are still on 3.3. It’s time to upgrade your dedicated cluster if you have not already done it!

### RabbitMQ 3.7

RabbitMQ 3.7 passed CloudAMQP internal testing in February 2018. It has since then been available as an upgrade option, via the CloudAMQP control panel.

**Important note:** A full cluster restart is required for all dedicated clusters to get the new version. If you cannot have any downtime, we recommend upgrading by creating a new cluster and after that migrate to the new cluster, for example with help of queue federation.
