We've cut a new release candidate, v2.1.0-rc1 (https://github.com/zmap/zlint/releases/tag/v2.1.0-rc1). This is a minor release that primarily includes bug fixes and new lints. Testing would be appreciated.
If you find any problems feel free to report them on Github Issue #430. We plan to cut a final v2.1.0 release next week if no problems are identified, per the "Versioning and Releases" guidance in the README.
