In aiohttp 3.12 we'll have support for partitioned cookies, but this is dependent on upstream support in Python 3.14+.
If anyone needs support in an older release of Python, it can be monkey patched with this code:
if sys.version_info < (3, 14):
from http import cookies
# See: https://github.com/python/cpython/issues/112713
cookies.Morsel._reserved["partitioned"] = "partitioned"
cookies.Morsel._flags.add("partitioned")I'll leave this as a pinned issue for a couple of years until the feature is more widely available without monkey patching.
