v1.6.1 (2021-04-07)

This release includes several bug fixes, such as a vivisect issue that prevented capa from working on Windows with Python 3. It also adds 17 new rules and a bunch of improvements in the rules and IDA rule generator. We appreciate everyone who opened issues, provided feedback, and contributed code and rules.

Upcoming changes

This is the very last capa release that supports Python 2. The next release will be v2.0 and will have breaking changes, including the removal of Python 2 support.
