 **7.2.0**
 
 - Basic MacOS X support (contribution by @rubendibattista)
+- Introduce variables `wireguard_conf_owner`, `wireguard_conf_group` and `wireguard_conf_mode` (contribution by @rubendibattista)
+- Fixed a typo bug in `handlers/main.yml` (contribution by @gabriel-v). But it looks like this had no impact on the "sync/restart" functionality.
+- Proper formatting of WireGuard configuration file (`wg0.conf` by default). This will most probably change the WireGuard configuration file but only the formatting. But since the Ansible registers this file as changed Ansible will sync/restart WireGuard service. For newer WireGuard versions (since Nov. 2019) this isn't a problem normally as `wg syncconf` command is used (also see `handlers/main.yml`).
+- Introduce `wireguard_dc` variable. This is an alpha feature and subject to change and may be even removed in future releases again. Therefore no documentation for this variable yet.
 
 **7.1.0**

 In general WireGuard is a network tunnel (VPN) for IPv4 and IPv6 that uses UDP. If you need more information about [WireGuard](https://www.wireguard.io/) you can find a good introduction here: [Installing WireGuard, the Modern VPN](https://research.kudelskisecurity.com/2017/06/07/installing-wireguard-the-modern-vpn/).
 
-This role is tested with Ubuntu 18.04 (Bionic Beaver), Ubuntu 20 (Focal Fossa) and Archlinux. Ubuntu 16.04 (Xenial Xerus), Debian 9 (Stretch), Debian 10 (Buster), Fedora 31 (or later) and CentOS 7 might also work or other distributions but haven't tested it (code for this operating systems was submitted by other contributors). If someone tested it let me please know if it works or send a pull request to make it work ;-)
