Patch 5.2.0h Edit
Patch 5.2.0h is the unofficial name for the patch build 16760 that came out about 5 days after the unofficially named "Patch 5.2.0g" build 16733. There is no info on this patch build and there has been no official acknowledgement of the release of this patch build. This client could also correspond to the March 21, 2013 slate of hotfixes. It isn't clear why a client patch is needed.
