Aurora is on version 1.9.5 C#, available at the Aurora Forums.
Contact Erik on the forum for a wiki account.
This template is to be used on all pages that are game version specific.
"There's a new version! What do I do?"
If the version is major enough to warrant a new namespace, then the most important thing to do is update this page with the newest namespace. This will cause all the templates to show the proper current/outdated message.
The second thing to do is update the ArticleVersion template. This template is widely used and quite complicated; please do not attempt to modify it unless you are very familiar with wiki template code. Instead, please post an update request on its talk page.
