Security updates are applied only to the most recent release.
If you have discovered a security vulnerability in this project, please report it privately. Do not disclose it as a public issue. This gives me time to work with you to fix the issue before public exposure, reducing the chance that the exploit will be used before a patch is released.
Please disclose it at security advisory.
This project is maintained by one volunteer on a reasonable-effort basis. As such, please give me at least 90 days to work on a fix before public exposure.
