Older and pre-release/beta/untested versions are available at [the releases page](https://github.com/github/VisualStudio/releases), and also via a custom gallery feed for Visual Studio.
You can configure the gallery by going to `Tools / Options / Extensions and Updates` and adding a new gallery with the url https://visualstudio.github.com/releases/feed.rss. The gallery will now be available from `Tools / Extensions and Updates`.
