## Feature Feature GKE is introducing the following changes to expand the capabilities of maintenance exclusions: * **Per-node pool maintenance exclusions**: Available in release channels, these replicate the functionality of disabling node pool auto-upgrades when your cluster isn't enrolled in a release channel. * **Extended "No upgrades" exclusion**: The "No upgrades" default maintenance exclusion can now be up to 90 days long.
