v5.1.0
capa version 5.1.0 adds a Protocol Buffers (protobuf) format for result documents. Additionally, the Vector35 team contributed a new feature extractor using Binary Ninja. Other new features are a new CLI flag to override the detected operating system, functionality to read and render existing result documents, and a output color format that's easier to read.
Over 25 capa rules have been added and improved.
