As part + of this, these three options are no longer supported: + + gnutls_require_kx + gnutls_require_mac + gnutls_require_protocols + + Their functionality is entirely subsumed into tls_require_ciphers, which is + no longer parsed apart by Exim but is instead given to + gnutls_priority_init(3), which is no longer an Exim list. See: + + http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html + + for fuller documentation of the strings parsed. The three gnutls_require_* + options are still parsed by Exim and, for this release, silently ignored. + A future release will add warnings, before a later still release removes + parsing entirely and the presence of the options will be a configuration + error. + + This rewrite means that Exim will continue to build against GnuTLS in the + future, brings Exim closer to other GnuTLS applications and lets us add + support for SNI and other features more readily. We regret that it wasn't + feasible to retain the three dropped options. + Exim version 4.77 ----------------- |
