What
The preview tunnel lets a remote view reach a server running on your own machine. For requests to that local machine it now passes along any request type, such as GET or POST, except CONNECT. Ports other than the tool server's port now go through this relay too, instead of the earlier fetch that handled redirects manually. Redirects are not followed.
Why
This changes how the preview tunnel behaves for local servers.
