 ## Application Setup
 
 During container start, it will first check if the wireguard module is already installed and loaded. Kernels newer than 5.6 generally have the wireguard module built-in (along with some older custom kernels). However, the module may not be enabled. Make sure it is enabled prior to starting the container.

 ## Parameters
 
-Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.

 ## Versions
 
+* **03.10.23:** - **Potentially Breaking Change:** Support for multiple interfaces added. Wireguard confs moved to `/config/wg_confs/`. Any file with a `.conf` extension in that folder will be treated as a live tunnel config and will be attempted to start. If any of the tunnels fail, all tunnels will be stopped. Tunnels are started in alphabetical order. Managed server conf will continue to be hardcoded to `wg0.conf`.
 * **24.06.23:** - Deprecate armhf as per [https://www.linuxserver.io/armhf](https://www.linuxserver.io/armhf).
 * **26.04.23:** - Rework branches, swap alpine & ubuntu builds.
 * **28.01.23:** - Patch wg-quick to suppress false positive sysctl warning.
