3.5.12

Caution

In upgrading to MKE 3.6.x, be aware that MKE versions 3.6.0 to 3.6.3 run a version of etcd that is older than the version Mirantis includes with MKE 3.5.10. As such, MKE 3.5.10 can only be upgraded to MKE 3.6.4 or later.

The etcd component, by design, will not accept a downgrade of itself.
