This version is released on 2017-09-12.

New Features

• Optimizations to the fuzzy hashing engine. (hash generator can run as twice as fast and comparison can run 1.5 through 5 times faster [heavily depends on the data and platform] than the previous release)

Sorry, @a4lg initially used wrong benchmark on the version 2.14 release. The time of hash comparison heavily depends on the hash set and platform and "five times performance boost" only occurs in rare situations. On x86_64 platform, hash comparison could run 1.5 through 2.5 (maybe 3) times faster than the previous release (excluding rare and extreme situations).

Bug Fixes

• Fixed issue when certain memory allocation is failed.

Known Issue

There is a known issue on the prebuilt Win32 archive. On fuzzy.dll, fuzzy_hash_file and fuzzy_hash_stream functions will not work properly if you build the program which uses fuzzy.dll with Visual C++.

This issue is being addressed on issue #1.

As a workaround, use fuzzy_hash_filename function or manual computation functions instead. ssdeep.exe does not have this issue.

Notice

ssdeep is now maintained by the ssdeep project (current project maintainer: Tsukasa OI [@a4lg]).
