3.12.7rc0

Bug fixes

• Fixed cookie parsing to be more lenient when handling cookies with special characters
  in names or values. Cookies with characters like {, }, and / in names are now
  accepted instead of causing a :exc:~http.cookies.CookieError and 500 errors. Additionally,
  cookies with mismatched quotes in values are now parsed correctly, and quoted cookie
  values are now handled consistently whether or not they include special attributes
  like Domain. Also fixed :class:~aiohttp.CookieJar to ensure shared cookies (domain="", path="")
  respect the quote_cookie parameter, making cookie quoting behavior consistent for
  all cookies -- by :user:bdraco.

• Fixed an issue where cookies with duplicate names but different domains or paths
  were lost when updating the cookie jar. The :class:~aiohttp.ClientSession
  cookie jar now correctly stores all cookies even if they have the same name but
  different domain or path, following the :rfc:6265#section-5.3 storage model -- by :user:bdraco.

  Note that :attr:ClientResponse.cookies <aiohttp.ClientResponse.cookies> returns
  a :class:~http.cookies.SimpleCookie which uses the cookie name as a key, so
  only the last cookie with each name is accessible via this interface. All cookies
  can be accessed via :meth:ClientResponse.headers.getall('Set-Cookie') <multidict.MultiDictProxy.getall> if needed.
