-## Reporting a Vulnerability
-
-Please report directly via email to a@rejetto.com for Responsible disclosure.
-I should normally reply within 2 days, so we can agree on timings.
+If you're still using HFS 2.x, I recommend migrating to HFS 3, which is actively maintained in a separate repository: https://github.com/rejetto/hfs
