Upgrades

Rolling upgrades from a Mesos 1.7.0 cluster to Mesos 1.7.1 are straightforward. However, if your framework is consuming the experimental support for CSI, the language binding used by the framework should be updated.

For detailed information on upgrading to Mesos 1.7.1 from other versions, please refer to the upgrade guide.
