Welcome to **hashcat v7.1.0**!
---

This is a minor release, but an important one. It comes just two weeks after the major v7.0.0 update, as part of our effort to keep release cycles shorter than in the past.

Although two weeks may seem quick, this version includes several important bug fixes along with notable new features and hash modes, which makes a v7.1.0 release fully justified.
