 ### New Features {#new-features-1-16-0}
-* _All features of the Embedded Cluster 1.15.0 release are now available in the Embedded Cluster 1.16.0 release._
 * Adds support for Kubernetes 1.30.
-* Adds a new command to the Embedded Cluster binary, `admin-console reset-password`, which allows resetting the password for the Admin Console.
-* Adds a new flag, `--cidr`, that replaces the `--pod-cidr` and `--service-cidr` flags. The specified CIDR range will be split and used for the Pod and Service CIDRs.
-* Adds a new preflight check to verify that the CIDR range used for the cluster does not overlap with existing routes.
+* Adds a `--data-dir` flag to the `install` and `restore` commands so the data directory can be specified. By default, the data directory is `/var/lib/embedded-cluster`. If the `--data-dir` flag was provided at install time, then the same data directory must be provided when restoring. For more information, see [Embedded Cluster Install Command Options](/reference/embedded-cluster-install) and [Disaster Recovery for Embedded Cluster](/vendor/embedded-disaster-recovery).
+* Adds an `admin-console reset-password` command to the Embedded Cluster binary, which allows resetting the password for the Admin Console.
+* Adds a `--cidr` flag to the `install` command that replaces the `--pod-cidr` and `--service-cidr` flags. The CIDR range specified with the `--cidr` flag is split and used for both the Pod and Service CIDRs. See [Embedded Cluster Install Command Options](/reference/embedded-cluster-install).
+   :::note
+   The `--pod-cidr` and `--service-cidr` flags are hidden, but still functional. Replicated recommends that you update any automation that uses the `--pod-cidr` and 
+   `--service-cidr` flags to use the `--cidr` flag instead.
+   :::
+* Adds the following preflight checks:
+  * Verify that the CIDR range used for the cluster does not overlap with existing routes.
+  * Verify the CPU supports x86-64-v2.
+  * Verify the data directory (`/var/lib/embedded-cluster` by default) is not symlinked.
 
 ### Improvements {#improvements-1-16-0}
+* For new installations, the `k0s` and `openebs-local` directories are now subdirectories of `/var/lib/embedded-cluster`. With this change, Embedded Cluster now only documents and includes preflight checks for `/var/lib/embedded-cluster`.
 * Improves the reliability of waiting for the Kubernetes server to start.
-* Removes the `--data-dir` flag from the `shell` and `reset` commands.
 * Collects more information about the cluster in support bundles, including the Local Artifact Mirror and Kubernetes API Server logs.
+* Requires that the Admin Console password is at least six characters.
+* Removes the `--data-dir` flag from the `shell` and `reset` commands.
 
 ### Bug Fixes {#bug-fixes-1-16-0}
-* Fixes an issue when resetting a worker node that used a custom data directory.
-* Fixes an issue where k0s images were not being updated within the cluster when k0s was upgraded.
-* Fixes an issue where upgrading a pre-1.15 cluster with a worker node would fail.
+* Fixes an issue that could occur when resetting a worker node that used a custom data directory.
+* Fixes an issue where k0s images were not updated within the cluster when k0s was upgraded.
+* Fixes an issue where upgrading a cluster with a worker node that used a version of Embedded Cluster earlier than 1.15 would fail.
 * Fixes an issue where the application could not be upgraded to a version that did not have a configuration file or preflights.
-* Fixes an issue where support bundle configurations in included remote URIs in Air Gap environments.
+* Fixes an issue where support bundle configurations in included remote URIs in air gap environments.
+* Fixes an issue that could cause the registry to fail to upgrade in air gap installations.
