A Shareable Cluster no longer requires the “Shared With” white list (applies to all releases, except R2019b which still requires the “Shared With” white list).	Anyone with the cluster profile can access the shared cluster (except in R2019b, which still requires the "Shared With" white list).	To restrict access with a "Shared With" white list, use R2019b only.	An existing "Shared With" white list has no effect on cluster access in any version except R2019b and should not be used in any other release with the expectation that this list would restrict user access to a cluster.
You can no longer export personal cluster profiles.	For Personal clusters, the export cluster profile option is no longer available. Personal clusters were introduced in R2019b. You can still export cluster profiles for any R2019b Shareable cluster and for any R2018a - R2019a cluster.	Cluster profiles for running personal clusters can be added to MATLAB via the Discover Clusters... option under the Parallel menu in MATLAB. Cluster profiles are automatically added to MATLAB by creating a new personal clusters via the Create Cloud Cluster option on the Cluster Profile Manager in MATLAB. The Cluster Profile Manager is accessed via the Create and Manage Clusters... option under the Parallel menu in MATLAB	None

Cluster Shared State
The cluster attribute Shared State enables Cloud Center to authorize users to submit jobs to or interact with a cluster from MATLAB. The Shared State may be Personal Cluster (accessible only by you) or Shareable Cluster (accessible to people you have explicitly given access to via a white list). The default Shared State attribute of a cluster is Personal Cluster. This authorization control is unrelated to accessing the cluster via SSH.
For Shareable Clusters, the person creating the cluster must expressly add authorized users to the Shared With field.
Note
Cloud Center clusters created for MATLAB releases prior to R2019b did not have clusters with the Shared State attribute. Those clusters are all implicitly shareable clusters, as any user who imports a cluster profile is authorized to submit jobs to or interact with the cluster from MATLAB. The inbound firewall rules for these clusters are managed only by Global Cluster Access rules.
For more information, see Sharing Options for Clusters.
Auto-Manage Cluster Access
The cluster attribute Auto-Manage Cluster Access allows Cloud Center to manage a cluster’s inbound firewall rules on a cluster-by-cluster basis. Auto-Manage Cluster Access is enabled by default for Personal Clusters.
Note
Clusters created prior to R2019b are Shareable Clusters, whose inbound firewall rules are managed only by Global Cluster Access rules.
For more information, see Manage Cluster Access Automatically.
