yeah it looks like it only revolves around letting people have authority to ban unwanted people from an estate.. Here is the information straight from the patch notes..

""To bar a character from your property, you must first be on your estate grounds and have the requisite authority. Target the character you wish to bar, and select "Bar from Property" in the subcommand menu, then choose "Register as Barred Character." They will be ejected from the estate grounds and moved to the housing area entrance.

Barred characters will remain on the Barred Characters list for 10 days. During this time, any attempts to enter your estate hall or garden will instead transport them to the housing area entrance.

To view or adjust these settings, select Housing from the Social menu, followed by Estate Settings, then Estate Holder Rights. Authorization settings will differ according to the type of residence.

Free Company Estate
The free company master is the main rightsholder, and may appoint up to four free company members as secondary rightsholders.

Personal Estate
The estate owner is the main rightsholder, and may appoint up to three tenants as secondary rightsholders.

Apartment / Private Chambers
The apartment or private chambers owner is the main rightsholder, and cannot appoint secondary rightsholders.

It should be noted that, when secondary rightsholders with the setting enabled are present on an estate, characters on their blacklist may also be denied access to the property. Which rightsholders' blacklists will be included to determine who is barred from the estate may be adjusted via the Estate Holder Rights window.""
