   * Maintenance release: refine splitting of [[user@]host:]dataset[:with-colons][@snap[:with-colons]] strings to work for the realistic majority of use-cases; fix back support of pool root dataset in such spec
   * Update self-tests with verification that [[user@]host:]dataset[:with-colons][@snap[:with-colons]] string decoding yields expected results
   * Fixed CI recipes and contents for spell-checker

+## FreeBSD

+For systems based on FreeBSD, you can copy the generated ```znapzend.freebsd```
+file to ```/etc/rc.d/znapzend``` and make sure it is executable, and then add
+the following line(s) to your ```/etc/rc.conf``` file to enable or disable
+znapzend as a service:
+
+```sh
+# znapzend_enable (bool):	Set to "NO" by default.
+#				Set it to "YES" to enable znapzend.

+
+If you want to set parameters for the znapzend daemon separately from the
+rc-script, copy ```znapzend.default``` to ```/etc/defaults/znapzend```
+and edit it. Note that the rc-script in all cases provides a set of its
+own ```command_args``` to manage daemonization, logging and PID file use.
