Changes in Varnish 6.1

This release is a maintenance release, so while there are many actual changes, and of course many bugfixes, they should not have little to no impact on running Varnish installations.

Nothing to see here, really

Since new users often forget to vcl.discard their old VCLs, we have added a warning when you have more than 100 VCLs loaded. There are parameters to set the threshold and decide what happens when it is exceeded (ignore/warn/error).

We have made req.http.Host mandatory and handle requests without it on the fast DoS avoidance path.

For all the details and new stuff, see :ref:whatsnew_upgrading_6.1
