     1** Version 0.8.3 (2017-10-20)
     2- Use GnuTLS' default DH parameters by default
     3- Handle long Server Name Indication data and gracefully ignore
     4  unknown SNI types
     5- Send SNI for proxy connections
     6- Deprecate OpenPGP support like GnuTLS did (will be removed
     7  completely in a future release)
     8- Do not announce session ticket support for proxy connections
     9- Minor documentation updates (SSL_CLIENT_I_DN, reference for SNI)
     10- Test suite: Simplify handling of proxy backend servers and OCSP
     11  responders
     12- Test suite: stability/compatibility fixes
     13
    114** Version 0.8.2 (2017-01-08)
    215- Test suite: Ensure CRLF line ends in HTTP headers

    189 You can generate this file using `certtool --generate-dh-params --bits
    190 2048`.  If not set `mod_gnutls` will use the included parameters.
     187By default, `mod_gnutls` uses the DH parameters included with GnuTLS
     188corresponding to the security level of the configured private keys if
     189compiled with GnuTLS 3.5.6 or newer, and the ffdhe2048 DH group as
     190defined in RFC 7919, Appendix A.1 otherwise.
     191
     192If you need to use different DH parameters, you can provide a PEM file
     193containing them in PKCS \#3 encoding using this option. Please see the
     194"[Parameter
     195generation](https://gnutls.org/manual/html_node/Parameter-generation.html)"
     196section of the GnuTLS documentation for a short discussion of the
