 ### DXGL 0.5.17
 Due to a bug found in the method used to uniquely identify profile paths, DXGL 0.5.17 and above will perform a one-time renaming of the profile registry keys.  These new profiles will no longer be compatible with DXGL 0.5.16 or below.

+## 64-bit Build Notice
+The 64-bit build of DXGL is intended solely for targeting 64-bit DirectDraw programs.  For usage with 32-bit programs, please download the 32-bit build.  The 32- and 64-bit versions of DXGL install in separate folders and Start Menu entries, and have separate profiles.  The configuration program will not create profiles for mismatched platforms; you can only add profiles for 64-bit programs in the 64-bit build, and 32-bit programs in the 32-bit build.
