An update for Nuclear Dawn has been released. It is required for dedicated servers. This update includes upstream Source Engine improvements, including the following:

• Various security and stability improvements.
• Fixed physics not operating at the correct tickrate when specifying non-standard -tickrate options on the command line.
• Lag compensation system will now reliably restore pose parameters responsible for animation layering. (This makes server-side hitboxes for lag compensated players better match client-side rendered models).
