 Changelog
 ---------
 
-**6.3.1**
-
-- Support Openstack Debian images (contribution by @pallinger)
-
-**6.3.0**
-
-- Support Raspbian (contribution by @penguineer)
-
-**6.2.0**
-
-- Support Ubuntu 20.04 (Focal Fossa)
-- Introduce `wireguard_ubuntu_update_cache` and `wireguard_ubuntu_cache_valid_time` variables to specifiy individual Ubuntu package cache settings. Default values are the same as before.
-- As kernel >= 5.6 (and kernel 5.4 in Ubuntu 20.04) now have `wireguard` module included `wireguard-dkms` package is no longer needed in that case. That's why WireGuard package installation is now part of the includes for the specific OS to make it easier to handle various cases.
-
-**6.1.0**
-
-- Archlinux: Linux kernel >= 5.6 contains `wireguard` module now. No need to install `wireguard-dkms` anymore in this case. Installations with LTS kernel installs `wireguard-lts` package now instead of `wireguard-dkms`. Installations with kernel <= 5.6 will still install `wireguard-dkms` package.
-
-**6.0.4**
-
-- Use the buster-backports repository on Debian Buster (or older), use package standard repositories on sid/bullseye.
-  standard repositories on sid/bullseye.
-
-  The role no longer adds the unstable _repo_ nor the _apt preference_ for that repo. There is no need to clean the preference and unstable repository, since packages from your release have a higher priority.
-
-  If you remove the apt preference (`/etc/apt/preferences.d/limit-unstable`) updates from `unstable` are accepted by apt. This likely is not what you want and may lead to an unstable state.
-
-  If you want to clean up:
-    * remove `/etc/apt/preferences.d/limit-unstable` and
-    * remove `deb http://deb.debian.org/debian/ unstable main` from `/etc/apt/sources.list.d/deb_debian_org_debian.list`.
-
-  The backports repository has a lower priority and does not need an apt preference.
-
-**6.0.3**
-
-- If `wg syncconf` command is not available do stop/start service instead of restart (contribution by @cristichiru)
-
-**6.0.2**
-
-- Debian: install `gnupg` package instead of `gpg`. (contribution by @zinefer)
-
-**6.0.1**
-
-- add shell options to syncconf handler to fail fast in case of error
-
-**6.0.0**
-
-- Newer versions of WireGuard (around November 2019) introduced `wg syncconf` subcommand. This has the advantage that changes to the WireGuard configuration can be applied without disturbing existing connections. With this change this role tries to use `wg syncconf` subcommand when available. This even works if you have hosts with older and newer WireGuard versions.
-
-**5.0.0**
-
-- `wireguard_(preup|postdown|preup|predown)` settings are now a list. If more `iptables` commands needs to be specified e.g. then this changes makes it more readable. The commands are executed in order as described in [wg-quick.8](https://git.zx2c4.com/wireguard-tools/about/src/man/wg-quick.8). Also see README for more examples. (contribution by @Madic-)
-

 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/).

If someone tested it let me please know if it works or send a pull request to make it work ;-)

-By default port `51820` (protocol UDP) should be accessable from the outside. But you can adjust the port by changing the variable `wireguard_port`. Also IP forwarding needs to be enabled e.g. via `echo 1 > /proc/sys/net/ipv4/ip_forward `. I decided not to implement this task in this Ansible role. IMHO that should be handled elsewhere. You can use my [ansible-role-harden-linux](https://github.com/githubixx/ansible-role-harden-linux) e.g. Besides changing sysctl entries (which you need to enable IP forwarding) it also manages firewall settings among other things. Nevertheless the `PreUp`, `PreDown`, `PostUp` and `PostDown` hooks may be a good place to do some network related stuff before a WireGuard interface comes up or goes down.

-The commands are executed in order as described in [wg-quick.8](https://git.zx2c4.com/wireguard-tools/about/src/man/wg-quick.8).
-
 `wireguard_address` is required as already mentioned. It's the IP of the interface name defined with `wireguard_interface` variable (`wg0` by default). Every host needs a unique VPN IP of course. If you don't set `wireguard_endpoint` the playbook will use the hostname defined in the `vpn` hosts group (the Ansible inventory hostname). If you set `wireguard_endpoint` to `""` (empty string) that peer won't have a endpoint. That means that this host can only access hosts that have a `wireguard_endpoint`. That's useful for clients that don't expose any services to the VPN and only want to access services on other hosts. So if you only define one host with `wireguard_endpoint` set and all other hosts have `wireguard_endpoint` set to `""` (empty string) that basically means you've only clients besides one which in that case is the WireGuard server. The third possibility is to set `wireguard_endpoint` to some hostname. E.g. if you have different hostnames for the private and public DNS of that host and need different DNS entries for that case setting `wireguard_endpoint` becomes handy. Take for example the IP above: `wireguard_address: "10.8.0.101"`. That's a private IP and I've created a DNS entry for that private IP like `host01.i.domain.tld` (`i` for internal in that case). For the public IP I've created a DNS entry like `host01.p.domain.tld` (`p` for public). The `wireguard_endpoint` needs to be a interface that the other members in the `vpn` group can connect to. So in that case I would set `wireguard_endpoint` to `host01.p.domain.tld` because WireGuard normally needs to be able to connect to the public IP of the other host(s).
 
 Here is a litte example for what I use the playbook: I use WireGuard to setup a fully meshed VPN (every host can directly connect to every other host) and run my Kubernetes (K8s) cluster at Hetzner Cloud (but you should be able to use any hoster you want). So the important components like the K8s controller and worker nodes (which includes the pods) only communicate via encrypted WireGuard VPN. Also (as already) mentioned I've two clients. Both have `kubectl` installed and are able to talk to the internal Kubernetes API server by using WireGuard VPN. One of the two clients also exposes a WireGuard endpoint because the Postfix mailserver in the cloud and my internal Postfix needs to be able to talk to each other. I guess that's maybe a not so common use case for WireGuard :D But it shows what's possible. So let me explain the setup which might help you to use this Ansible role.
