Hugo deprecation warnings

Hugo warns not to use certain language constructs anymore:

WARN 2019/05/30 01:17:21 Page's .Hugo is deprecated and will be removed in a future release. Use the global hugo function.
WARN 2019/05/30 01:17:21 Page's .URL is deprecated and will be removed in a future release. Use .Permalink or .RelPermalink. If what you want is the front matter URL value, use .Params.url.
WARN 2019/05/30 01:17:21 Page's .UniqueID is deprecated and will be removed in a future release. Use .File.UniqueID.

A suitable patch could look similar to

Now we also get a

WARN 2019/05/30 02:11:39 .File.UniqueID on zero object. Wrap it in if or with: {{ with .File }}{{ .UniqueID }}{{ end }}

from the menu.html partial.
