Congrats on the release! I was following up the development progress on GitHub.
I'm pretty excited about "Plugin Interface". I think we can this refactor effort as a success story: simpler code + improved performance + more testing.
It's amazing that they've added this tutorial for adding new algorithm: https://github.com/hashcat/hashcat/blob/master/docs/hashcat-... (previously information was scattered around PRs).
Thanks atom and all the other contributors!
