-### New Features {#new-features-1-15-0}
-* Adds the `--data-dir` flag to the `install` command so the data directory can be specified. By default, the data directory is `/var/lib/embedded-cluster`.
-
-### Improvements {#improvements-1-15-0}
-* Adds a preflight check to ensure the CPU supports x86-64-v2.
-* Adds a preflight check to ensure the data directory (`/var/lib/embedded-cluster` by default) is not symlinked.
-* Adds the `--data-dir` flag to the `restore` command. When restoring a backup that used a non-default data directory (i.e., the `--data-dir` flag was provided at install time), the same data directory must be provided when restoring.
-* For new installations, the `k0s` and `openebs-local` directories are now subdirectories of `/var/lib/embedded-cluster`. We will only document and preflight for `/var/lib/embedded-cluster` now.
-* The Admin Console password must be at least six characters.
-
-### Bug Fixes {#bug-fixes-1-15-0}
-* Fixes an issue that could cause the registry to fail to upgrade in air gap installations.
