Hey list,

We have been working hard towards this first release, so I encourage you to take Johnny version 2.0 for a spin.

I'll chip in with a couple clarifications embedded bellow.

This release has many under the hood fixes and improvements. We didn't keep a proper CHANGELOG previous to this release, but we're planning on doing so from this point onwards.

This is the first proper release in more than three years of inactivity. Now that we have a release procedure set in place, future releases should come easier. Expect more frequent and agile releases from this point onwards, at least for the duration of this GSoC iteration.

We still have some grounds to cover in regards to cleaning up the Wiki pages and the afferent documentation and DISTFILES.

A clarification here. Johnny is supposed to work with both core John and the jumbo version. However, using jumbo will enable features like hash type suggestion in the Passwords table and automatic attack formats pre-filling. We still have a couple adjustments to make in regards to core John usage, but in coverage terms, we exhausted the list of juice we can get out of it. As a rule of thumb, you're better off if you're using the freshest john version available to you, since fixes in regards to Johnny have been incorporated into JtR.

That being said, we're going to focus on adding more juice and functionality from the jumbo side of things next. Expect cool features next.
