Certbot 5.1.0 has just been released. The changelog for the release is:

5.1.0 - 2025-10-07

Changed

  • certbot-nginx no longer creates and uses self-signed certificates as an
    intermediate step when installing certificates. The certificates the user
    requested Certbot install are now always used instead.
    (#10465)
  • The function acme.crypto_util.make_self_signed_cert was deprecated and will
    be removed in a future release.
    (#10466)

Fixed

  • Fixed a bug in certbot-nginx that'd leave nginx configured with self-signed
    certificates if a user ran certbot enhance and they didn't have matching
    SSL server blocks. certbot enhance now requires the user to have a matching
    SSL server block to enable HSTS or OCSP stapling enhancements.
