         * Compatibility changes
           - The one-step hashing functions, MD4(), MD5(), RIPEMD160(), SHA1(),
             all SHA-2, and HMAC() no longer support returning a static buffer.
+            Callers must now pass in a buffer to calculate the digest.
           - Removed workaround for F5 middle boxes.
           - Removed the useless pem2.h, a public header that was added since
             it was too hard to add a prototype to one file.
