Release notes for the Mines of Moria expansion are up. You can even download the PDF online manual and check the Lore-Book for more Mines of Moria news and changes.

Some things to do:

• If you have pre-irdered or if you did the early upgrade you can add the key to your account at http://myaccount.turbine.com to get the items and benefits from pre-ordering.
• If you bought a digital upgrade you will need to download and install on the same day that LOTRO: MoM launches. If you are awaiting for the pro-order retail box you will need to download the 2.7GB patch and apply it once Turbine announces MoM on the servers.

Players who do not have the expansion on November 18th will have to download the 2.7GB patch and continue playing Shadows of Angmar without the option to enter the new areas.
