+- Update the default behavior of
+ ``pyramid.authenticationAuthTktAuthenticationPolicy`` and
+ ``pyramid.authentication.AuthTktCookieHelper`` to only set a single cookie
+ without a domain parameter when no other domain constraints are specified.
+ Prior to this change, ``wild_domain=False`` (the default) was effectively
+ treated the same as ``wild_domain=True``, in which a cookie was defined
+ such that browsers would use it both for the request's domain, as well as
+ any subdomain. In the new behavior, cookies will only affect the current
+ domain, and not subdomains, by default.
