-#### Allow references to parent properties in org.zfsbootmenu:commandline
+### Allow references to parent properties in org.zfsbootmenu:commandline
 
 Any reference to `%{parent}` in `org.zfsbootmenu:commandline` will be replaced with the value of the same property on the parent filesystem (with parent references above recursively expanded), allowing easy specification of common options at a mutual parent of two BEs and overrides or additions of individual options per-BE. The value of `%{parent}` is always an empty string on a root filesystem.
 
 This is not intended to be sophisticated, and `%{parent}` appearing within other words will be replaced regardless. The assumption is that `%{parent}` is unique enough and will not conflict with real KCL options, so dumb global replacement is sufficient.

-#### `hostid` configuration assistance
+### `hostid` configuration assistance
 A pair of new features have been developed to combat the delicate dance sometimes required to synchronize `hostid` in the boot environment (BE), the initramfs for the BE, and the initramfs for ZFSBootMenu. Both of these are controlled by ZFSBootMenu kernel command line options.
 
 Set `zbm.import_policy=hostid` to allow run-time reconfiguration of the SPL hostid. If a pool is preferred via `zbm.prefer` and the pool can not be imported with a preconfigured hostid, the system will attempt to adopt the hostid of the system that last imported the pool. If a preferred pool is not set and no pools can be imported using a preconfigured hostid, the system will adopt the hostid of the first otherwise-importable pool. After adopting a detected hostid, ZFSBootMenu will subsequently attempt to import as many pools as possible.

 ### Minor new features
 
-#### Boot environment / snapshot sorting
+### Boot environment / snapshot sorting
 The main boot environment screen and snapshot list screen can now be sorted by multiple criteria. By default, these listings are sorted by name. One of `zbm.sort_key=name`, `zbm.sort_key=creation`, or `zbm.sort_key=used` can be set on the command line to change the default used. `MOD+O` can be pressed at run time to change the sort order to the next in the list.
 
-#### Helper functions in the recovery shell
+### Helper functions in the recovery shell
 
 The internal `zfsbootmenu-lib.sh` library is now sourced by default in the recovery shell. This makes a number of helper functions available for general use.
 
-#### Combined command line printer
+### Combined command line printer
 
 Since `Dracut` can find command line options from multiple places, it can be difficult to determine which option was used to control bootloader behavior. The command `zbmcmdline` will show the command line as seen by Dracut.
 
-#### Shorcut key layout improvements
+### Shorcut key layout improvements
 
 Instead of flowing the helper key text to the width of the screen, shortcut key text is now arranged in one or more columns. Low resolution screens or terminals with small dimensions will use a single column to show the text. As the terminal dimensions increase, text will be laid out in up to a maximum of three left-aligned columns.
 
-#### Logging system
+### Logging system
 
 ZFSBootMenu has an internal logging system backed by `/dev/kmsg` and `dmesg`. Logging is now enabled throughout the entire system, tracking both `debug` level messages as well as `warnings` and `errors`. When a warning or error condition has occurred, a yellow `[!]` or red `[!]` notification will appear in the upper left of the screen. Pressing `MOD+L` will access this logging system, allowing you to easily see these messages.

 Any time you transition from one menu to another (Snapshots, Kernels, recovery shell), the list of boot environments and kernels is completely regenerated. This helps remove potential disconnects between the state of your pool and boot environments and the ZFSBootMenu interface.
 
-#### UEFI bundle improvements

 If you create unversioned UEFI bundles for static boot entries, `generate-zbm` will now create a `-backup` file for you on upgrade. This will allow you a recovery option if the active UEFI bundle has a problem.
 
-#### Protect against missing kernel modules
+### Protect against missing kernel modules
 
 When creating a new initramfs, the `zfsbootmenu` Dracut module needs to install a number of ZFS-related kernel modules. Previously, the modules were installed through a Dracut helper function that did not verify if the copy succeeded. This process has been reworked to ensure that all of the required kernel modules are installed in the initramfs, or the creation of the image is marked as a failure. If it is marked as a failure, existing/current images are not deleted or otherwise replaced.

-## Large changes
+### Large changes
 * Clean up or whitelist all issues in `zfsbootmenu-lib.sh`, `zfsbootmenu-preview.sh` and `zfsbootmenu.sh` noted by shellcheck.
 * Support entering a custom kernel command line via `alt-c` on the main menu. The input line is pre-filled with the command line that would have been used on the next boot, for that environment. This command line is NOT persisted between reboots, it's simply here to let you recover an unbootable system.
 * Add support for reading the kernel commandline from the ZFS property `org.zfsbootmenu:commandline`.  This property is now considered the default/primary source of truth for the kernel command line - it takes precedence over `/etc/default/zfsbootmenu` and `/etc/default/grub`.
