Get Feather Client

I'm currently testing the Dawn Client beta and encountering persistent bugs/crashes. I suspect the issue is related to an incompatibility between the current beta build and the version of Feather Client I have installed.

To troubleshoot, I need to downgrade Feather Client to an older, more stable version that is confirmed to work with this Dawn Client beta. However, I'm unable to find a clear method to roll back to a previous Feather Client version.
