新版本改進包括支持基于 MD5 加密 crypt(3) 和 Apache $apr1$ 哈希的破解，改進了 Raw MD4 破解等等，詳細內容：

OpenMP support has been added for MD5-based crypt(3) and Apache $apr1$ hashes when building with SSE2 intrinsics, as well as for SAP CODVN B and SAP CODVN G. Raw MD4 has been enhanced with optional SSE2 intrinsics. The SSE2 intrinsics code for MD4, MD5, and SHA-1 has been pre-built with Intel's compiler into an assembly file, used with the new i-suffixed make targets. Support for occasional false positives or multiple correct guesses has been added and made use of for WinZip/AES and CRC-32. md5_gen has been renamed to dynamic. Numerous other fixes and enhancements have been made
