 ## Patch section for version 1.0.5 and above of GPT fdisk by Joseph Zeller.
-## Class variable PartType::unusedPartType is removed and replaced with the
-## associated GUID value used in previous versions of gdisk to prevent hang.
+## Class variable unusedPartType is defined as GUIDData instead of PartType
+## to prevent a freeze caused by the default GUIDData constructor accessing
+## UEFI (time) services before the full initialization process is complete.
