 Before you can use WireGuard (or any VPN solution), you need a mechanism for your remote clients to reach your home router. You have two choices:
 
 1. Obtain a permanent IP address for your home router from your Internet Service Provider (ISP). Approach your ISP if you wish to pursue this option. It generally involves additional charges.

 ## Breaking changes
 There are a few changes that you need to be aware of:
-* Docker Environmental `*.env` files are no longer a thing by default. Everything needed is specified in the service.yml file, you can still optionally use them though either with [Custom Overrides](https://sensorsiot.github.io/IOTstack/Custom) or with the [PostBuild](https://sensorsiot.github.io/IOTstack/PostBuild-Script) script. Specific config files for certain services still work as they once did.

 * Python 3, pip3, PyYAML and Blessed are all required to be installed.
 * Not backwards compatible with old menu system. You will be able to switch back to the old menu system for a period of time by changing to the `old-menu` branch. It will be unmaintained except for critical updates. It will eventually be removed - but not before everyone is ready to leave it.
