Rust XMPP server Lonewolf hits v0.3, adds real federation and TLS

Lonewolf, a standalone XMPP server written in Rust, has released version 0.3.0. This update introduces significant new features, most notably certificate-authenticated federation, which allows it to exchange messages and presence information with other XMPP servers on the internet. It also adds support for Direct TLS connections and includes several new XMPP protocol extensions for private data storage and server discovery, moving the project closer to a full-featured, modern chat server.

For engineers, this represents a notable step for a promising open-source project. The addition of federation is a core feature for any server meant for real-world use. However, it's important to note this is still a pre-1.0, single-node server, meaning full clustering and complete XMPP compliance are still future goals. The takeaway is that Lonewolf is maturing into a viable, performance-focused alternative in the XMPP ecosystem, built with the safety and concurrency benefits of Rust.
