Returning player - How do I update files?

[Eyecue]

Left circa July 2014 (Kunark was not yet out) and now need file updates b4 I can resume play. Is it best to just simply wipe EQ and re-install with current version? That would be my guess. Unless there exists another way besides looking back over all the single patch releases.

(I checked the forums as best I could, and did not see this addressed, tho I am quite sure it is out there and I just missed it.)
