 ## Bleeding Edge Builds
 
 We also have a [nightly build](https://github.com/AvaloniaUI/Avalonia/wiki/Using-nightly-build-feed) which tracks the current state of master. Although these packages are less stable than the release on NuGet.org, you'll get all the latest features and bugfixes right away and many of our users actually prefer this feed!
