Hi,

another trouble I had when updating was with the ciphers.

=46rom https://configurator.tlsref.org/ I get the following[0]:
openssl_options =3D +no_sslv2 +no_sslv3 +no_tlsv1 +no_tlsv1_1
tls_eccurve =3D X25519MLKEM768:X25519:prime256v1:secp384r1
tls_require_ciphers =3D ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-=
SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDS=
A-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305

unfortunately, the tls_eccurve option is not working and produces errors
due to X25519MLKEM768.

On much lower version on devuan os that settings was working. But I
think, devuan uses gnutls instead of openssl. On gentoo, gnutls is
incompatible with dane so that is not an option.

Any idea what happened to that option?

Regards
   Klaus
