Maintained fork

[sheerlox]

@mbramson hey, thank you for the really useful lib! ❤️

Because the project seems unmaintained, I've forked the project to unill-io/content_security_policy, merged the level 3 CSP directives PR, and made a few improvements as well as adding some automation. The fork is maintained by our dev team and has been used in production by our company since July 🎉

Of course, feel free to integrate some of the changes into your repository if you can find the time to work on this project again, and if you'd like us to prepare and send localized PRs from our changes, let us know!
