It hasn't received updates in a good long while, but seems to work fine, for me anyway. Has some rough edges, logging blocks when there's a bunch of redirects is a bit of a pain, making it hard to fix whitelisting in complicated things (like the dozen domains microsoft uses for auth) but apart from that...
(and ofc there's a bunch of forks adding bugfixes, some even relatively recent in activity, but unfortunately none have become the blessed official maintainer)
