+- The `portunus` package and service do not support weak password hashes anymore.
+  If you installed Portunus on NixOS 23.11 or earlier, upgrade to NixOS 24.05 first to get support for strong password hashing.
+  Then, follow the instructions on the [upstream release notes](https://github.com/majewsky/portunus/releases/tag/v2.0.0) to upgrade all existing user accounts to strong password hashes.
+  If you need to upgrade to 24.11 without having completed the migration, consider the security implications of weak password hashes on your user accounts, and add the following to your configuration:
+  ```nix
+  services.portunus.package      = pkgs.portunus.override { libxcrypt = pkgs.libxcrypt-legacy; };
+  services.portunus.ldap.package = pkgs.openldap.override { libxcrypt = pkgs.libxcrypt-legacy; };
+  ```
