Release Notes¶
Considerations
As MKE 3.6.0 runs etcd 3.4.16, upgrading to it from MKE 3.5.6 or later (which run etcd 3.5.5) will fail. As such, it is necessary to upgrade instead to MKE 3.6.1 or later.
The etcd component, by design, will not accept a downgrade of itself.
MKE 3.6.0 requires MCR 20.10.13 or later, which you must install or upgrade to prior to installing or upgrading to MKE 3.6.0.
Upgrading from one MKE minor version to another minor version can result in the downgrading of MKE middleware components. For more information, refer to the middleware versioning tables in the release notes of both the source and target MKE versions.
CentOS 8 entered EOL status as of 31-December-2021. For this reason, Mirantis no longer supports CentOS 8 for all versions of MKE. We encourage customers who are using CentOS 8 to migrate onto any one of the supported operating systems, as further bug fixes will not be forthcoming.
