 ## Library Updates
 
+### [Lightyear 0.13][lightyear_website]
+
+[lightyear_website] is a comprehensive networking library for bevy to make multiplayer games.
+It comes with multiple types of transports (WebTransport, WebSocket, UDP, etc.) 
+and supports replication techniques like client-side prediction, server interpolation, interest management and more!
+Check out the [examples][lightyear_examples]!
+
+The latest release, [0.13][lightyear_release], brings two big new features:
+- **Steam support**: you can now use the Steamworks SDK as your transport layer, which lets you use the Valve network!
+Note that lightyear supports running multiple transports in parallel, so it's possible to have cross-play between steam and non-steam users.
+- **Listen-server mode**: it is not possible to run a server and a client in the same process/bevy app.
+This is can be useful to avoid the costs of a dedicated server, or to have a similar codebase between singleplayer and multiplayer.
