As I write this, the Chapter V content patches--there are likely to be two or three, it's a big download--are not yet available. When they are, you will be able to find them here:

Alternatively, you can wait for the servers to come back up and start the client so it can auto download and patch. And, some time after I get up early in the morning, I'll be going to the EU website to get the patch information and update Tigsman's Manual Patch thread.
In other words...I counsel patience, Weedhopper.

Patching will be available soon.
UPDATE:
As of approximately 12:30am PDT, the Chapter V patches were available via client download. In addition, Tigsman's Manual Patch List has been updated to include the four (4) new content patches.
