 # Revision history:
 #
+# 0.6.3   -- Support for detecting rEFInd in EFI/BOOT and EFI/Microsoft/Boot
+#            directories & for installing to EFI/BOOT in BIOS mode
 # 0.6.2-1 -- Added --yes option & tweaked key-copying for use with RPM install script
 # 0.6.1   -- Added --root option; minor bug fixes
 # 0.6.0   -- Changed --drivers to --alldrivers and added --nodrivers option;
