1.65B has gone up on the Pendragon test server, you can read the brief notes on the CamelotHerald, for now here is a snippet:

- Effective immediately, you may only use /house in the region where your house is located. Note that you can use house for both guild and personal houses, so be certain you are checking the right house when you use the command. - Merchants are now properly saved on the marketplace. All players will need to use the /listmerchant command once to clear their merchant and once again to relist all of their items.
