https://github.com/discourse/discourse/pull/8308 removes the per-category
suppress_from_latest setting, migrating these settings into the
default_categories_muted setting. This works well for logged in users, however it doesn’t cover logged-out users, at least in my testing:
You’ll see posts from the “Off-Topic” and “Sessions” categories, which are in
default_categories_muted, if you’re logged out: Mozilla Discourse Staging
This is a regression from the
suppress_from_latest category setting, so it would be great to have it re-implemented.
