I updated to 1.7.2 but Empire Minecraft server still runs on 1.6.4 and I missed the halloween promo completely, . Any dates on the 1.7 server update?
To elaborate. If you click the edit profile option on the launcher, in the middle of the page you will see a drop down list of clients (will default to "latest version"). You can choose 1.64 from that list and be playing right now
though... we totally forgot to remove the /shop stands, so you can still buy haunted heads there.. but it will be gone by the weekend end.
