This is an alpha release for people interested in trying out an early preview of 2.0. Major features include performance improvements, triage options, new output modes, and many new checkers thanks to our Google Summer of Code students @Niraj-Kamdar, @SinghHrmn and @SaurabhK122 . Thanks for an incredibly productive summer!
We are expecting to make some documentation improvements before the final release, which we hope to have out next week.
