Granted, the situtation with pymemcache isn’t significantly better (no releases in 3 years either, but at least their CI does target py313, albeit with a version of gevent that is too old to compile in the test requirements).
So I have to wonder out loud: should we stop recommending pylibmc without better maintenance?
Reading up on the history, the Django backend for python-memcached was deprecated in Django 3.2 and removed in 4.1. It’s unfortunate that now it might be in one of the better maintenance postures. Maybe that counsels against deprecating anything else.
