- As of this release, the ``request_method`` predicate, when used, will also
imply that ``HEAD`` is implied when you use ``GET``. For example, using
``@view_config(request_method='GET')`` is equivalent to using
``@view_config(request_method='HEAD')``. Using
``@view_config(request_method=('GET', 'POST')`` is equivalent to using
``@view_config(request_method=('GET', 'HEAD', 'POST')``. This is because
HEAD is a variant of GET that omits the body, and WebOb has special support
to return an empty body when a HEAD is used.
