 ## What's the current status of WireGuard?
 
-[WireGuard reached "stable" 1.0.0 release](https://lists.zx2c4.com/pipermail/wireguard/2020-March/005206.html) in Spring 2020. It has undergone [substantial](https://www.wireguard.com/formal-verification/) security review. Releases are tagged with their build date -- "0.0.YYYYMMDD" -- and users should be advised to apply new updates when they are available. Your Algo server will automatically upgrade and restart WireGuard. For Ubuntu 18.04 LTS, it will retrieve updates from the [official WireGuard PPA for Ubuntu](https://launchpad.net/~wireguard/+archive/ubuntu/wireguard) by default.
