Backed out changeset 73a45ba6e3f1 in favour of 427dd01f0864 New behaviour (muc_room_allow_persistent = true, the default): - Parent host users are not restricted by default (prosody:user) - Users without roles (by default that is non-admins, non-parent-host users, and users on other servers) can no longer configure persistence by default. muc_room_allow_persistent = false will restrict persistence to prosody:admin. Parent-host users should not be restricted by default, and this can be configured via the new roles/permissions options.
