^ I ended up copying over the updates from 1.15 so that people don't have to cross-reference those notes. Worth a review to make sure everything looks right

* Adds support for Kubernetes 1.30.
* 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 that 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.

^ added this note to clarify that the flags are not yet removed but that cidr should be used 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.

^ grouped the new preflights


### 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.
* 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.

### Bug Fixes {#bug-fixes-1-16-0}
* 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 included remote URIs in air gap environments.
* Fixes an issue that could cause the registry to fail to upgrade in air gap installations.
