John the Ripper v1.8.0 Released
John the Ripper is free and Open Source software, distributed primarily in source code form. If you would rather use a commercial product tailored for your specific operating system, please consider John the Ripper Pro, which is distributed primarily in the form of “native” packages for the target operating systems and in general is meant to be easier to install and use while delivering optimal performance.
- Revised the incremental mode to let the current character counts grow for each character position independently, with the aim to improve efficiency in terms of successful guesses per candidate passwords tested.

- Added makechr, a script to (re-)generate .chr files.
- Enhanced the status reporting to include four distinct speed metrics (g/s, p/s, c/s, and C/s).
