v6.1.0

capa v6.1.0 is a bug fix release, most notably fixing unhandled exceptions in the capa explorer IDA Pro plugin. @Aayush-Goel-04 put a lot of effort into improving code quality and adding a script for rule authors. The script shows which features are present in a sample but not referenced by any existing rule. You could use this script to find opportunities for new rules.

Speaking of new rules, we have eight additions, coming from Ronnie, Jakub, Moritz, Ervin, and [email protected]!
