Full Changelog: https://github.com/mhmdiaa/second-order/compare/v3.1...v3.2

• Moved headers from the configuration file to a separate flag.
• Added graceful Ctrl+c handling. Second-order now saves the results it collected up to the point where it was killed before exiting.
• Reduced false-positives by checking for 404 status code or unregistered domains specifically, since that's how most of the takeover-able services behave.
• Made the stdout output more accurate and concise by printing the URLs that have not been visited only.

Major rewrite with performance improvements, more efficient memory usage, and support for more use cases
